How To Choose A Laptop Battery

How to choose a laptop battery?

What you need to know about Li-ion (lithium-ion) laptop batteries

To the pluses of Li-ion battery can be attributed, lack of memory effect. Once fully charged, NO trickle charge is required and the Li-ion battery can remain in the charger while not in use.

Lack of Li-ion the battery is susceptible to aging, even if not in use.

Capacity degradation occurs after about one year and the battery often fails in the second and third year.

Therefore, it is not recommended to store Li-ion batteries for a long time.

Enjoy them as much as possible while they are new.

Maximum service life stated by cell manufacturers. Is 5 years old.

Has become unusable, the Li-ion battery cannot be restored with the introduction of charge-discharge cycles, as is the case with other types of batteries.

The only possible repair is to replace the battery cells, but there are also some nuances here: laptop lithium-ion batteries are implemented as a serial string of cells, and an increase in capacity is achieved by connecting the strings in parallel.

When the batteries are connected in series, there is a danger of overcharging the weakest of them, with parallel. the difference in their internal resistance turns out to be significant: a battery with a lower resistance will be charged with a higher current.

Both have a disastrous effect on battery life. All battery cells must have the same parameters, therefore partial replacement of damaged cells with new ones will not lead to the expected result. Elements must also be from the same batch, elements from different batches have different parameters.

The aforementioned danger of overcharging means the following: overcharging can lead to an increase in pressure in the cell and depressurization.

Therefore, the safety of battery operation is always ensured by an external electronic protection system against overcharging and overdischarging of SEPARATE batteries.

It includes controllers that measure the voltage of each battery or block of parallel-connected batteries, and a switch to open the electrical circuit when the voltage limits are reached. Thermistors are used to monitor battery temperature.

Another disadvantage of Li-ion batteries is the fear of a strong discharge (overdischarge).

The aforementioned protection circuit is powered directly from the batteries, and therefore if the cells are completely discharged, the circuit stops working and the cells are not charged, in addition, a deep discharge negatively affects the internal structure of the cells themselves.

It is believed that the optimal range for the operation of li-ion cells is 20-100% of the charge, the output below 20% leads to faster aging of the cells.

The service life of Li-ion cells is calculated Not only in years of service, but also in charge-discharge cycles, as a rule, to a decrease in capacity by 20%, they provide 500 1000 cycles.

The further behavior of the elements is rather difficult to predict due to the large number of cells in the battery, most often there is a gradual decrease in capacity, sometimes abruptly, therefore the protection system keeps track of the number of cycles.

On older battery models, when a certain cycle value was reached, the protection system closed the battery, and it was not possible to use it.

The ability to close the battery when a certain number of cycles is reached remains today, just the number of cycles prescribed in the battery is large enough, and the aging of the cells, and therefore the drop in capacity, occurs earlier.

As a rule, the counter value can be reset to zero, however, do not forget that using such a battery is somewhat unsafe, the cells in the battery age unevenly, which means that they are charged and discharged also unevenly.

There is another difficulty associated with the counter, what is to be counted as a charge-discharge cycle? Full discharge and full charge?

But it is not recommended to completely discharge it. And whether to read in a cycle a short-term disconnection from the network?

Most modern batteries do not charge if the current charge is more than 90-95%, this avoids unnecessarily high rates of charge-discharge cycles.

The figure 90%.95% is relative. On some laptops, it can be edited with special utilities.

As for the storage conditions, there is unambiguous information on this issue.

The most common opinion is that it is necessary to store at a charge of about 40% periodically (once every two to three months) recharging to this value.

Generally, Li-ion batteries perform best at room temperature.

Operation at elevated temperatures dramatically shortens their lifespan.

At low temperatures, battery performance decreases.

A temperature of minus 20 ° C is the limit at which Li-ion batteries cease to function.

How to choose a laptop battery? Briefly and to the point

Once you are here, then you are at least interested in the questions “how to choose a battery”, “how do they differ” and “how to use them correctly”. All this is in this article. Let’s start with the main thing.

Our managers will offer you all the possible options that we have in stock or in our suppliers in Ukraine and abroad. The suggested batteries will work 100% in your laptop and come with a 3 or 6 month warranty.

It remains only to decide what to take: the original or a copy.

First, let me tell you the fundamental difference between them.

What is an original battery and what are “copies”?

The original battery is always of excellent quality.

A durable, beautiful-looking and pleasant-to-touch plastic of the case is used, there is no unpleasant smell of “cheap China”, the gaps are exactly maintained everywhere, the case is firmly glued, a high-quality connector with precisely fitted contacts is used, which is firmly held in the case of the battery itself. On the body of the battery itself, there are stickers with clearly printed markings and an easy-to-read font. Service stickers are often present (serial number, sps part number, etc.)

In general, “took it in hand. Hold the thing”!

Copies are of very different quality, ranging from “very SIMilar to the original” to a flimsy construction made of smelly plastic with a whitish tint, in which an NOT attached connector with contacts is loose, between which the gap can vary greatly.

The stickers on such a battery are poorly printed, there is little text and it is usually smeared or they may not be at all.

All batteries that come with a new laptop can be safely called original, i.e. Supplied by the manufacturer.

In addition, for the original battery, you can contact an authorized service (although this does NOT guarantee that the “original” will be sold to you there).

A copy of the market is flooded with Chinese factories, which, in principle, can be engaged in the production of batteries, but there is no control over the quality of the manufactured product, and the race to reduce leads to cheaper production and an uncontrolled decrease in the quality of laptop batteries.

So what to choose?

If the question of saving money is not on your agenda. You should definitely take the original battery.

This will protect you from problems “connected. Contacts bent”, “connected, but the laptop does not see it”, “kept the charge normally for a month and stopped”, etc.

If, after all, you are limited by means. You can take a copy without any problems.

By and large, although these batteries often look “not very”, they have a minimum of 3 months warranty, and experience shows that most of them work No worse than the originals.

The only thing worth paying attention to is that the contacts should NOT be bent, the case would not open, the stickers would not come off, there were no traces of old stickers, scratches and other traces of use.

Here you can see for Laptop Batteries.

All your questions will be answered with pleasure by our manager in the chat, by phone, on applications and via any second communication channel.

A bit of history

It starts with the fact that the technology of manufacturing alkaline nickel batteries (NiCd) was proposed in 1899, but the first NiCd battery appeared in 1947.

At one time, these batteries were really almost the only ones. The emergence of newer electrochemical batteries, although it led to a decrease in the use of NiCd batteries, however, the identification of the shortcomings of new types of batteries led to renewed interest in NiCd batteries. Nicd battery is like a strong and silent worker who works hard and does NOT cause much trouble.

The first thing that catches your eye. This is the weight and dimensions of the batteries. Nicd battery. The largest and heaviest, it is about twice as thick and heavier as NiMH. It is harmful for NiCd batteries to remain in the charger for several days. In fact, NiCd batteries are the only type of battery that performs best when subjected to full discharge from time to time. All other types of batteries according to the electrochemical system prefer a shallow discharge.

So, for NiCd batteries, a periodic full discharge is important, and if it is not performed, NiCd batteries gradually lose efficiency due to the formation of large crystals on the cell plates, a phenomenon called the memory effect.

The emergence of nickel-magnesium (NiMH) batteries is due to an attempt to overcome the disadvantages of nickel-cadmium batteries.

Benefits NiMH versus NiCd:

  • Less prone to memory effect than NiCd. Periodic recovery cycles Must be performed less frequently.
  • Capacity: NiMH batteries have about 30% more capacity than a standard (not very high capacity) NiCd battery of the same size.
  • Less toxicity. Nimh technology is considered environmentally friendly.
  • READ  Increase Cooler Speed ​​On Laptop

    disadvantages NiMH versus NiCd:

  • Cycles: the number of charge / discharge cycles for NiMH batteries is approximately 500.
  • Shallow rather than deep discharge is preferred. The longevity of batteries is directly related to the depth of discharge.
  • Fast charging: NiMH batteries generate significantly more heat during charging compared to NiCd batteries. In addition, the NiMH battery cannot be charged as quickly as the NiCd; charge time. Usually twice as much as NiCd.
  • Self-discharge: Both NiMH and NiCd batteries have acceptably high self-discharge. A Nicd battery loses about 10% of its capacity during the first 24 hours, after which the self-discharge is about 10% per month. Self-discharge of NiMH batteries. 1.5-2 times higher than NiCd.
  • Price: NiMH batteries are about 30% more expensive than NiCd.
  • In 1970, the first commercial copies of primary lithium power sources appeared.

    Attempts to develop rechargeable lithium power supplies were made in the eighties, but were unsuccessful due to the inability to provide an acceptable level of safety when handling them. As a result of studies carried out in the 80s, it was found that during the charge and discharge of the first lithium batteries, dendrites are formed on the lithium surface.

    The germination of dendrite to the positive electrode and the occurrence of a short circuit inside the lithium current source is a prerequisite for the failure of the element.

    In this case, the temperature inside the battery can reach the melting point of lithium.

    An explosion occurs as a result of the violent chemical interaction of lithium with the electrolyte. For example, a large number of lithium batteries delivered to Japan in 1991 were returned to manufacturers after several people were burned as a result of cell phone battery explosions.

    Another type of popular battery is lithium polymer.

    The difference from Li-ion lies in the name itself and lies in the type of electrolyte used, it is understood that a dry solid polymer electrolyte is used, however, today technologies DO NOT allow such an element to be made, therefore a gel-like electrolyte is used, and as a result we get some kind of hybrid.

    Such batteries DO NOT belong to either pure li-ion or Li-pol, and it would be more correct to call them lithium-ion polymer, however, manufacturers call them lithium-polymer to promote batteries. As for the pros and cons of li-pol, they are exactly the same as those of li-ion, so further we will consider li-ion, because they are the most common today.

    Let’s sum up the results in a comparative table for different types of batteries

    • Nicd (nickel cadmium batteries for household devices):
      Features::
      – memory effect (decrease in battery capacity without periodic full discharge)
      – heavy weight;
      – lower capacity for the same dimensions (compared to NiMH batteries)
      fast charge (compared to NiMH batteries)
      lower self-discharge (1.5-2 times compared to NiMH batteries).
      Operating and storage conditions:
      – the need for a full discharge-charge cycle (to avoid memory effect).
    • Nimh (Nickel-magnesium batteries for household appliances):
      Features::
      – slow charge (compared to NiCd batteries)
      – higher self-discharge (1.5-2 times compared to NiCd batteries)
      – preference for surface discharge over full;
      30% higher capacity with the same dimensions (compared to NiCd batteries)
      lack of memory effect;
      less weight (in comparison with NiCd-batteries).
      Operating and storage conditions:
      – DO NOT deep discharge (keep the charge at least 20%);
      – DO NOT leave a discharged battery for long-term storage.
      – DO NOT expose to temperatures below or equal to 20 ° C and elevated temperatures;
      – store and use at room temperature.
    • Li-Ion (lithium-ion power supplies for laptop batteries):
      Features::
      – aging even if not used;
      – preference for surface discharge over full;
      lack of memory effect;
      low weight and design in any volume.

    Basic parameters of laptop battery

  • Its output voltage (10.8V, 11.1V, 14.4V, 14.8V, etc.). Measured in volts.
  • Its capacity (4400mAh, 4800mAh, 5200mAh, 6600mAh, etc.). Measured in milliampere hours.
    For example, 4400mAh = 4.4Ah (amp hours), i.e. Conventionally, the ability of the battery to deliver a current of 4.4 amperes for an hour. You should NOT take such an explanation literally, since the discharge of the battery is a non-linear process, in addition, the batteries can produce current limited by the controller to prevent heating and damage to the internal structure).
  • Sometimes the battery provides data in the stored power. For example 55 Wh (Watt hours).
  • This is a more complex parameter, but more accurately conveys the energy capacity of the battery. Conventionally, it can be considered the product of the output voltage of the battery by its capacity in ampere hours.

    In fact, this is an integral parameter calculated from the area of ​​the graph of the voltage on the battery at a given discharge current per full discharge cycle.

    You should not bother to understand this whole process, it is enough to understand that the larger this figure, the greater the capacity of the battery.

    For an approximate calculation of the capacity in milliAmpere-hours, section this figure for voltage. For example 55 Wh / 10.5 1000 = 5238 mAh.

    DO NOT treat your laptop battery like a regular battery.

    Of course, the battery also has a positive “” and a negative “-” contact, but besides this, there is a controller inside the laptop battery that closely “monitors” the charging and discharging currents, as well as the configuration of the battery capacity.

    To do this, the laptop battery has 3 information pins 2 for serial communication via the digital SM Bus and one for receiving information about the battery temperature.

    From this follows a small conclusion about the compatibility of batteries: even if the battery fits in its shape. DO NOT rush to insert it into your laptop.

    Although usually all batteries are very different and if it is of the same shape, then this is a 90% guarantee that it is from your laptop model.

    In any case, we recommend looking for a rechargeable battery Armed with the name of its model (it is on the case of the battery itself)!

    If you want to pick up a battery with a larger capacity, be prepared for the fact that it can be significantly larger in size due to the installation of additional Li-ion cans.

    Naturally, it will indicate a larger capacity parameter in mAh and, most importantly, there is a high probability that in laptops 3 or more years ago you will have to update the BIOS firmware so that this battery is correctly recognized by the laptop and starts charging.

    In addition, due to the increased number of capacitive cells in the battery, a different voltage may be indicated on it, for example, 14.8V instead of 11.1V.

    Now let’s get back to what batteries are in principle and what their features are:

    NICKEL-CADMIUM BATTERY. (Or NiCd for short) nickel cadmium;

    NICKEL METAL-HYDRIDE BATTERY. (Or NiMH for short) nickel metal hydride;

    LITHIUM ION BATTERY. (Or Li-ion for short) lithium-ion batteries. This is exactly the type of battery used in modern laptops.

    The latter are the most common and considered to be the best batteries.

    Operating and storage conditions for laptop batteries

  • DO NOT deep discharge (keep charge at least 20%);
  • DO NOT leave a discharged battery for long-term storage.
  • DO NOT expose to freezing temperatures, especially below 20 ° C and high temperatures;
  • Store and use at room temperature and 40% charge level with periodic recharging.
  • Battery selection options

    The laptop battery is selected in accordance with the manufacturer’s recommendations. For an accurate selection, it is advisable to know the model and P / N (partnumber) of the native battery, this information can be found on its labeling stickers. As an example, in the picture below, we define the model, voltage and capacity of the Toshiba battery:

    Using this analogy, you can quite easily find the marking of your battery.

    Rechargeable batteries are selected according to several main characteristics:

    • Battery Type. Most modern laptops use lithium-ion batteries, and Apple products are equipped with modern lithium-polymer batteries. Older models used nickel-cadmium and nickel-metal hydride batteries, now they are quite difficult to find.
    • Capacity is a key parameter that affects battery life. The higher the capacity, the larger it is. This parameter is measured in two versions: in millivolts / hours or in milliamperes / hours, both values ​​are usually indicated on batteries. You can choose a battery of the same or increased capacity.
    • Voltage. The difference in voltage does not have to exceed 0.5 V, therefore batteries with a voltage of 10.8 and 11.1 or 14.4 and 14.8 V are considered compatible. The batteries are equipped with a voltage correction module, but it must not be overloaded.

    How to choose a laptop battery?

    How to choose a laptop battery to replace a worn out battery and restore device mobility? Sooner or later, all laptop owners face such a problem: a standard battery is designed for about 400-600 charge and discharge cycles after that it becomes unusable and needs to be replaced. A new laptop battery must match the old one in all respects, and it is not necessary to purchase original components.

    Is it obligatory to purchase original components?

    Original batteries for Asus, Acer, Samsung and other popular brands are quite expensive, and such a purchase may not be justified for an old device. In addition, if the laptop has been in service for 3-4 years, it will be difficult to find original components for it. However, this does not mean that the problem cannot be solved: you can choose compatible components from well-known manufacturers.

    Compatible batteries have the same specifications as the original, but are available from other manufacturers. Most of the compatible products are manufactured in China and Hong Kong, but this is not to say about their low quality. Licensed companies produce quite high-quality and durable batteries, but they will cost much less, since the buyer does not need to overpay for the brand.

    If it so happens that you have an old battery from your laptop at hand and there is no way to independently find this information on the Internet, then we return to the selection of a suitable battery by the brand and model of the laptop.

    If you do not know the brand (manufacturer) and model of your laptop, and you have documents in which you can see this information, you need to do the following: Turn the laptop over and find a sticker with a barcode on which the exact name of the laptop will be indicated. If there is such a sticker on the bottom of the laptop, then it may be under the battery. Remove it and find the sticker or printed text on the laptop case.

    There are still questions. Read on. Do I have to buy an original battery

    Not at all. There are many laptop battery manufacturers who manufacture them under OEM contracts with major laptop labels (Acer, Apple, Asus, Dell, HP, Lenovo, Samsung, Sony, Toshiba, and others). OEM-made batteries are practically NOT inferior in quality to original ones, but they have a more attractive price, because It does not include brand fees.

    Does the laptop fit a battery with different specifications

    Will NOT work. The discrepancy between the voltage indicators in laptop batteries should not exceed 0.5 volts. Thus, batteries with voltages of 10.8 and 11.1 volts will be considered compatible; 14.4 and 14.8 Volts. The laptop battery uses a voltage regulation module (VRM). It serves to equalize the voltage of the laptop battery cells, because. There is a small error even with clear declared parameters.

    If the voltage differs by more than 0.5 Volts, that is, if you insert a 14.4V battery instead of 10.8V or vice versa, then this will cause an increased load on the voltage correction module, as a result of which it may overheat and generally burn out.

    Now everything is clear? It’s time to choose:

    • Batteries for Acer
    • Batteries for Asus
    • Dell Batteries
    • Batteries for HP
    • Lenovo Batteries
    • Batteries for MSI
    • Samsung Batteries
    • Sony Batteries
    • Batteries for Toshiba

    Attention! Further text for those who want to understand everything to the last comma and are NOT afraid of calculations;). Three steps to find the right battery:

    • Model. We decide on a laptop model or a battery model. The laptop model can be indicated near the screen, on the bottom or under the battery. The battery model is written on the battery itself. Can’t find your battery model? Read below.

    How to find the right battery for your laptop or netbook

    Useful tips for choosing a laptop or netbook battery

    How to quickly find the right battery for your laptop or netbook

    The most important criteria when choosing a laptop battery are its price, performance, durability and, of course, the origin.

    Let’s try to figure it out. In just three steps, you can determine which battery is right for your laptop and how to choose the right one. But if you want more details, then the information below will tell you all about the characteristics of laptop batteries.

    How to choose the right laptop battery

    Many users of portable computers (laptops) sooner or later face the problem of a significant decrease in the resource (power) of the laptop battery. This manifests itself, of course, in a reduction in the battery life of your device, and in the future, in the complete failure of the laptop to work on battery power. In such cases, your laptop battery should be replaced.

    Things to Consider When Selecting a New Laptop Battery?

    When choosing a new laptop battery, consider the following factors:

    • How often do you use your laptop for battery life.
    • The intensity of using a laptop in offline mode (i.e., if you are forced to use a variety of resource-intensive programs and applications when working offline, then you need to take into account that in this mode, the laptop battery will discharge much faster, compared to the introduction of a laptop in offline mode for Internet surfing or viewing (reading) a variety of text documents.
    • It’s also worth considering the dimensions and specifications of your laptop. Large notebooks with large screen diagonals have much higher power consumption compared to their smaller counterparts, netbooks. The battery life of a laptop is also influenced by its technical characteristics, for example, such as: the type of display backlighting (a display with led backlighting has significantly less power consumption compared to screens that have lamp backlighting) if your laptop is equipped with a powerful discrete graphics adapter and does not have an additional integrated card, then its battery life will be significantly lower compared to laptops with a hybrid graphics system (this solution is used by manufacturers to save energy, i.e. in cases where work with resource-intensive graphics applications is NOT required, the laptop runs on less productive and, accordingly, less power-consuming integrated card, but, if necessary, switches automatically to work from a more productive and, accordingly, more power-consuming discrete graphics adapter).

    Conclusion: If, due to circumstances, you use a laptop often enough for battery life and the battery life should be long (more than 2, 3 hours), and also, if you need a variety of resource-intensive applications and programs during battery life, then. it is worth thinking about buying a battery of increased capacity, the so-called reinforced battery. If you work mainly stationary, and the battery life of the laptop interests you insofar as, then, you can limit yourself to work from a regular battery, and if you need to replace it, replace it with a SIMilar one of the same capacity.

    In order to facilitate the search for a new laptop battery, if necessary, you need to know the following values:

    1. The capacity of your battery.

    In order to find out this parameter, the battery (battery) must be removed from the laptop and find on it the value that is indicated by the letters mAh, for example: 5200 mAh or 4400 mAh, this designation is an indicator of the capacity of the laptop battery. Accordingly, if your standard laptop battery has a capacity indicator, for example 5200 mAh, and you need to replace it with more capacious ones, then when searching you need to look for battery models compatible with your laptop with a higher capacity indicator, for example 7800 mAh or 9600 mAh.

    2. Your battery model.

    Any battery (battery) for a laptop has its own identifier assigned to it by the manufacturer. It can be designated model or part number (p / n), is a digital, alphabetic code, which can also be found directly on the battery by removing it from the laptop, it looks like this: model: as07d31.

    3. Laptop model.

    How to choose the right laptop battery

    Many users of portable computers (laptops) sooner or later face the problem of a significant decrease in the resource (power) of the laptop battery. This manifests itself, of course, in a reduction in the battery life of your device, and in the future, in the complete failure of the laptop to work on battery power. In such cases, your laptop battery should be replaced.

    Things to Consider When Selecting a New Laptop Battery?

    When choosing a new laptop battery, consider the following factors:

    • How often do you use your laptop for battery life.
    • The intensity of using a laptop in offline mode (that is, if you are forced to use a variety of resource-intensive programs and applications while working offline, then you need to take into account that in this mode, the laptop battery will discharge much faster, compared to the introduction of a laptop in offline mode for Internet surfing or viewing (reading) a variety of text documents.
    • It’s also worth considering the dimensions and specifications of your laptop. Large notebooks with large screen diagonals have much higher power consumption compared to their smaller counterparts, netbooks. The battery life of a laptop is also influenced by its technical characteristics, for example, such as: the type of display backlighting (a display with led backlighting has significantly less power consumption compared to screens that have lamp backlighting) if your laptop is equipped with a powerful discrete graphics adapter and does not have an additional integrated card, then its battery life will be significantly lower compared to laptops with a hybrid graphics system (this solution is used by manufacturers to save energy, i.e. in cases where work with resource-intensive graphics applications is NOT required, the laptop runs on less productive and, accordingly, less power-consuming integrated card, but, if necessary, switches automatically to work from a more productive and, accordingly, more power-consuming discrete graphics adapter).

    Conclusion: If, due to circumstances, you use a laptop often enough for battery life and the battery life should be long (more than 2. 3 hours), and also, if you need a variety of resource-intensive applications and programs during battery life, then. it is worth thinking about buying a battery of increased capacity, the so-called reinforced battery. If you work mainly stationary, and the battery life of the laptop interests you insofar as, then, you can limit yourself to work from a regular battery, and if you need to replace it, replace it with a SIMilar one of the same capacity.

    In order to facilitate the search for a new laptop battery, if necessary, you need to know the following values:

    1. The capacity of your battery.

    In order to find out this parameter, the battery (battery) must be removed from the laptop and find on it the value that is indicated by the letters mAh, for example: 5200 mAh or 4400 mAh, this designation is an indicator of the capacity of the laptop battery. Accordingly, if your regular laptop battery has a capacity indicator for example 5200 mAh, and you need to replace it with more capacious ones, then when searching you need to look for battery models compatible with your laptop with a higher capacity indicator, for example 7800 mAh or 9600 mAh.

    2. Your battery model.

    Any battery (battery) for a laptop has its own identifier assigned to it by the manufacturer. It can be designated model or part number (p / n), is a digital, alphabetic code, which can also be found directly on the battery by removing it from the laptop, it looks like this: model: as07d31.
