How to extend the life of your laptop battery

by Lou Horton on February 11, 2019

For the last several years most laptops have been built using Lithium-Ion batteries. While these batteries are lighter and have a greater life than their predecessors, the way that you use the battery can greatly impact the useful life. These modern batteries do not have “memory” like some older batteries but there are several things that you can do to make your battery last longer.  Lets dive in to what you can do to make your battery last longer.

There are two primary factors that will greatly impact the life of a Lithium-Ion battery: operating temperature and average charge level. You want to keep these batteries as cool as possible. Besides the obvious things like not leaving your laptop in a hot car, you can also minimize the operating temperature by not keeping the battery plugged into the charger unless it is actively being charged. When these batteries are plugged into the charger and fully charged, the internal temperature is typically about 45°C (113°F). A laptop that is run always plugged into the charger will lose about 35% of the total capacity in the first year and even more as the battery ages. If you need to always have your system plugged in (using a docking station for example) it is best to remove the battery. If you have the battery charged up to about 40% capacity and then remove it, the battery will remain viable for a long time.

It is not a good practice to fully discharge your battery on a regular basis before recharging it. Lithium-Ion batteries do best when they are recharged for short periods of time on a regular basis. An ideal usage pattern would be to run the laptop on the battery until the remaining charge is about 30-40% of the total capacity and then charging the battery to full capacity. Once the system is charged you should once again unplug it if possible.
