Maintaining battery life can be a moving target. Lithium Ion batteries are used in most electronics since 2013. Unfortunately, little has changed in battery technology for computer electronics.
Over time, between one and three years, laptop batteries lose much of their life expectancy. Below is a chart on the average loss based on the temperature that the battery is stored in:
|Storage Temperature||Charged to 40% – capacity loss after a year||Charged to 100% – capacity loss after a year|
|0 °C (32 °F)||2%||6%|
|25 °C (77 °F)||4%||20%|
|40 °C (104 °F)||15%||35%|
|60 °C (140 °F)||25%||40%|
If you plan on leaving for a trip, or stop using your laptop for a extended period of time, storing your device battery in a cold environment, like the fridge can prolong its life. To do this, let it discharge to about 40%, put it in a freezer bag, or better yet store it in a sealed container with desiccant’s that take oxygen out of the storage unit.
When you are ready to use the battery when you take it out of the fridge please make sure it sits in room temperature for a length of time that removes all condensation from the outside of the battery.
