Your laptop battery takes full advantage of power outlets and saves battery power when no power outlets are available. You can leave the battery connected to the laptop while using alaptop AC adapterto power the laptop.
Benefits of keeping the battery in your laptopThere is no need to remove the battery, there are benefits to keeping it.
First, if the battery is not fully charged, connecting it to the AC adapter will allow the AC adapter battery to fully charge over time.
Secondly, having a backup battery is helpful in case of power outages and brownouts. If either happens, you won’t lose any data because your laptop will switch to battery backup.
Finally, even when fully charged, keeping the battery connected while using the AC adapter will not damage the battery. Over time, all batteries eventually lose their ability to power your laptop and need to be replaced. This is normal for the battery and not a side effect of using the AC adapter with the battery connected.
When and how to remove a laptop battery while plugged in
If you have a removable laptop battery, sometimes removing it while the laptop is connected to an AC outlet can actually optimize your AC adapter battery life. However, if a power outage occurs while your laptop is plugged into an outlet without a battery, there is a risk of data loss.
Given the inconvenience of a power outage and the risk of data loss, is removing the battery worth it? In some cases, yes. We’ll look at when you should remove the battery from your laptop to optimize battery life, and explain how to do it.
Thermal issues and battery lifeOverheating is one of the worst things that can happen to your laptop battery. Battery life may be negatively affected when a battery is fully charged and heated for an extended period of time (such as when a laptop is plugged in and used).
If your laptop is on your lap, you may feel the heat generated by the battery. Placing pillows or blankets between you and your laptop will only exacerbate the problem, interfering with air circulation and the laptop’s ability to cool itself.
Resource-intensive tasks such as gaming and multimedia editing may further increase the heat generated by your laptop.
When to Remove a Laptop BatteryIf you’re going to be using your laptop connected to AC power for an extended period of time, especially if you’re performing heat-intensive tasks, removing the battery is a worthwhile step to take to extend its life. However, if you have frequent power outages at home or there are storms outside that may cause outages, keep your laptop battery connected and avoid the risk of data loss.
If you have an uninterruptible power supply (UPS) plugged in, no need to worry, just remove the battery.
If you’re on the road and plan to only keep the power on for an hour or so before needing the battery again, leave the battery connected. The process of shutting down the laptop, removing the battery, then restarting, then shortly powering down again to reconnect the battery (and turning the laptop back on again when reaching the next stop) is very inconvenient and time-consuming. When moving, keep the battery plugged in for short periods of time.
If you won’t be using your laptop for an extended period of time, such as on vacation or even on the weekends, it’s a good idea to remove the battery. This allows the battery to rest and potentially extend its life.
Do not remove or reinsert the battery while the laptop is running or even in sleep mode. Whenever you want to connect or disconnect the battery, it’s best to turn it off.
How to remove a laptop batteryWhen removing the battery from your laptop, be sure to perform these steps in this order.
Close the laptop.
Unplug the power cord from the laptop battery AC outlet.
Remove the battery.
Reconnect the power cord to the AC outlet.
Power on your laptop.
Storage Laptop BatteriesThe most common advice for laptop battery storage is to charge it to about 40% (or between 30% and 50%) and then store it in a dry place. Some manufacturers recommend storage temperatures between 68 and 77 degrees Fahrenheit (20 and 25 degrees Celsius), not too cold or too hot.
Some people keep batteries in the refrigerator, but this is risky and unnecessary. Doing so may damage the battery when it is exposed to moisture and condensation. Moisture and computer components don’t mix well.
You only need to remove the battery from your laptop if you need to perform a hard reset to power the laptop or replace internal hardware. Apart from this, the battery should always remain inside the laptop.
