There are plenty of myths and urban legends about certain things that can be done to extend the life of a battery, as well as a handful of misconceptions about what shortens or lengthens the life of a new laptop battery.
With some help from our friends at PCworld, here are a few tips on extending the life of a laptop battery.
1. Don’t run it all the way to empty
While it’s often suggested that a full cycle of power or two is good for a new battery when it is first in use, doing this often throughout the battery’s life can be detrimental to its longevity.
2. Keep the temperature down
Excessive heat wears on a battery and will shorten its lifespan. Keeping the vents and cooling systems clear on a laptop can help manage the temperature of a battery and, in turn, extend the life.
3. Disconnect it when using AC power
If your laptop is going to be staying put for a while, disconnecting the battery and relying solely on AC power can give the battery a much-needed rest. BUT… be sure that your computer is completely shut down before removing the battery. Removing the battery while the system is running can have damaging effects.
These are just a few items that can help extend the overall life of a battery. When it comes to the preservation of a single charge, things such as screen brightness and running applications can affect the time before recharging is needed. That’s a different topic for a different day however.
