The great advantage of notebooks is their mobile use and the power supply that is not always necessary. The notebook battery , which supplies the laptop with the required energy, is responsible for this. However, this does not last forever and in such cases it is beneficial to have a suitable replacement ready immediately. Which properties determine the purchase of a battery and what else should you pay attention to?
Different laptop battery types in comparison
Notebook batteries can come in 3 operating modes, which differ from one another in terms of the chemical compounds inside. As a result, each of these laptop battery types has different values in the areas of energy density , nominal voltage and service life .
- Lithium polymer
- Nickel ‑ metal hydride
The most common and most widespread type of battery is the lithium ‑ ion battery . They are not only used in notebooks, but also, for example, in smartphones and tablets. For this reason, Li-ion batteries benefit from rapid development and improved performance values as well as a longer service life. The batteries can be used for a certain number of charging cycles. A charging cycle consists of a complete charge including a discharge. The performance can also be influenced by unfavorable external conditions. For example, excessively high temperatures during storage reduce the capacity of the laptop battery.
Another major disadvantage of lithium polymer laptop batteries is that they are sensitive to temperature. The electrodes are not housed in liquid electrolytes inside, but in a gel-like film. This could be a problem, especially in winter, as the capacity and voltage level drop at very low temperatures. On the other hand, the voltage loss is kept within limits under normal circumstances and ensures longer runtimes. The lighter design of the battery is another benefit.
Nickel-metal hydride batteries are becoming increasingly rare in notebooks . Batteries of this type suffer from the battery inertia effect , which, through partial charging and discharging, causes the battery voltage to drop over the long term and leads to reduced performance. However, this effect is reversible, so it can be eliminated again by several complete charging and discharging cycles.
Choosing the right laptop battery capacity
The capacity of a laptop battery is given in mAh, which stands for milli-ampere hours . The duration of use depends on the connected device. For example, a 1000 mA battery can provide power for 1 hour or 200 mA for 5 hours. When the battery is discharged, the voltage collapses and no further power supply is possible. Batteries with a capacity of at least 6000 mAh are a good guideline for notebooks .
Buy original hardware or a compatible laptop battery?
As a rule, the notebook manufacturers also recommend the original notebook batteries for their models , which are equipped with high-quality cells and adapted charging and protection circuits. The only important thing here is that the right battery is selected for the notebook, as not every battery is suitable for every laptop.
Batteries from third-party manufacturers have developed as an inexpensive alternative. Companies such as MicroBattery or Whitenergy are not present on the notebook market with their own laptops, but still offer compatible notebook batteries . These are cheap and can be used for several different series at the same time. Especially here you should pay special attention to compatibility.
Windows can generate a “Battery Report” which will show the design capacity and the current capacity of your laptop battery. For Apple users, you can find your battery health statistics in System Settings > Hardware > Power. These two numbers will almost always be slightly different, but you will be able to see if there is a substantial reduction in capacity. If the disparity is great enough your computer will recommend that you change the battery. If the short runtime bothers you a new battery will help.
Some research has shown that the total service life of a battery can be extended by not fully charging and discharging the laptop battery. In some cases, your laptop will have a power management tool that can be set to restrict the amount of charge the computer gives the battery. If your computer offers this feature it is a wise idea to make sure the settings have not been changed to restrict the charge to a lower percentage.
There is also a chance that the laptop’s battery software is no longer correctly calibrated. This can be a result of swapping between batteries often, not rebooting your computer often enough or simply installing a new battery. Sometimes your laptop can have trouble distinguishing between a new replacement battery and the older worn out battery. The new battery usually is charging to 100% even though the power gauge software doesn’t correctly represent this.
Often with new batteries, the operating system is unable to correctly measure the charge in the new battery. Your laptop battery may be fully charged, but the power gauge is giving you a false reading. This can be because of some stored data relating to the former battery. If your laptop battery is not charging to 100% you may need to calibrate your battery.
Laptop Battery Power Cycle:
- Power down the computer.
- Unplug the wall adapter.
- Uninstall the battery.
- Press and hold the power button for 30 seconds.
- Re-install the battery.
- Plug in the wall adapter.
- Turn on the computer.
If the “Power Cycle” did not help, a full “Re-Calibration” might be needed. Below are the directions for calibrating the laptop battery software:
Note: If your computer will not recharge the battery at all this calibration will not help. This process may cause the battery to fail permanently if you are unable to recharge the battery immediately following the discharge.
Laptop Battery Calibration For Windows:
- The goal is to run the battery to zero percent, and for the computer to shut off without going to sleep or going into hibernate mode.
- Unplug your laptop from the wall.
- Change the “Power Plan” > “On Battery” > “Put the Computer to Sleep” settings to “Never.”
- If you cannot find these settings you can turn on an internet radio station, and let it play until the computer shuts off. (This is not effective in all versions of Windows)
- After the computer shuts down, plugging in the AC adapter should be required to turn the machine back on. Once the computer starts a message will appear asking if you would like to start in “Safe Mode.” Restart Windows normally.
- Leave your computer plugged in and charge it all the way from 0% to 100%.
- Remember to change your Power Scheme settings back to what they were.
Laptop Battery Calibration For Mac:
- Charge your battery to the highest percent available.
- Leave the laptop plugged in for 2 hours after you reach the topmost charge percentage.
- Unplug the AC adapter and use the computer until it forces the machine into hibernation mode.
- Let the computer stay in hibernation mode for 5 hours.
- Recharge the laptop battery from 0% to 100%.
If the re-calibration is performed correctly and does NOT fix the problem a new battery should correct the issue.
Does your laptop say its charging to a certain percentage but turn off as soon as you unplug the AC adapter?
If your computer shuts down immediately after unplugging the AC adapter, your battery has failed completely. The most common reason this happens is that the battery ran out of power completely. If a laptop battery runs to 0% and does not get recharged right away the computer will not allow that laptop battery to be used again. Laptop batteries have a computer chip inside each battery. This chip monitors the battery status and requests a charge from the laptop when required. The chip requires a small amount of energy from the laptop battery to continue functioning. When the battery loses all charge the computer can no longer communicate with the battery, and as a safety precaution, the computer will not allow electricity to be sent to the battery. Without the software in the chip to restrict the flow of electricity there would be a potential fire threat, so the laptop refusing to use the battery is a safety feature. Unfortunately, this is a non-fixable state, and a new battery is the only solution.
If your original battery still charges and discharges but your Xtend replacement battery will not, the new battery may have run to 0% or it may be a defective unit. This may be an indication that you need to replace your AC Adapter. It is more difficult to charge a new battery than it is to charge an older “broken in” battery. If your AC adapter is not outputting the correct amount of power you can run your computer, and charge an old battery, but you may be unable to charge a brand new battery.
If neither battery will recharge, you are most likely experiencing a failure in the laptop charge system (AC adapter, charge port, or motherboard charge circuit).

Top 10 reasons a Laptop Battery Will Not Charge1. Worn-out or Defective laptop charger Laptop power adapters can wear-out over time from kinks in the cord or from other wear and tear.2. Underpowered Laptop Charger Often times a laptop charger does not have enough power to charge the laptop battery while also running the laptop. This is common with extended run and universal laptop batteries and chargers. Be sure the power ratings on your laptop, battery and power cord all match up.3. Defective or worn-out power socket on laptop chassis This is one of the most common reasons why a laptop does not charge properly. Do you try to position your charger cord “just-right” until the charger light comes on? Chances are you need to replace the laptop power socket. This can be an easy fix with a little bit of research and the right tools.4. Laptop was not properly restarted when new battery was installed Some laptops need to be powered-down in order for them to recognize the new battery. Closing the laptop screen or using the on/off switch may only put your laptop into hibernate or sleep mode. Be sure to properly restart or power-down your laptop after installing the new battery.5. Battery was run all the way to zero percent If a battery was run all the way to zero percent, sometimes the battery will not have enough energy to power on. This battery is likely beyond repair and will need to be replaced.6. laptop Battery was not charged 100% before first use When batteries are new, they are not at 100% capacity yet. They need a little bit of exercise for them to hold their full charge. Charge the battery overnight and use until 20% then recharge the laptop battery again. Repeat this 5 times and your battery will be fully conditioned.7. Laptop was recently upgraded to a new version of Windows Changing the operating system on your laptop (especially Windows 7) may result in mixed communication between the laptop and the battery8. Battery management software is incorrectly calibrated. Sometimes Sometimes the battery may be charged but the power gauge is not reading accurately. This is common on extended run batteries. You may need to condition your laptop battery. Go to our calibrate a laptop battery page.9. laptop Battery is defective All laptop batteries and power cords from The Brand Store carry a 4 months warranty.10. Recharging circuit on motherboard is defective
A long-lasting notebook battery has many advantages. So you are independent of power sources even on longer trips and can use your laptop flexibly. In addition, an additional spare battery ensures a safe feeling during work and at the same time for a longer operating time. When buying, you should pay attention to the capacity and compatibility with the laptop. The notebook batteries from dynabook , Lenovo and Acer are in particularly high demand.
Does your original laptop battery discharge correctly, but never recharge to a higher percentage?
If your battery will not recharge at all, but will still discharge correctly, you are likely experiencing a problem with your charge system. Most commonly this means your adapter is beginning to fail, or you have damaged the power socket on the side of the computer where the charger plugs in. In more rare cases you could have experienced a failure in the charge circuit on the motherboard.
Does your battery correctly discharge and recharge even though it does not reach 100%?
If your battery will discharge and recharge, but gets stuck at a percentage less than 100%, you may have a failed cell in your battery, a problem with your power management settings, or a software calibration issue
