Charge your battery overnight when you first get your laptop. Then let the battery run down completely until there is no charge at all left in the battery. This is called cycling and often helps to extend the life of a new battery.
Store your battery in the refrigerator in a plastic bag when not in use. This will ensure that the battery stays dry, and the fluid between the electrodes will not evaporate or dry up due to heat. Simply put the battery in your laptop when you want to switch to battery power. Fast. Reliable. Affordable. Explore Epson's new WorkForce Pro.
Allow the battery to discharge completely once a month. This is a recommended procedure to extend the life of laptop lithium ion batteries.
Avoid subjecting your laptop lithium ion batteries to very hot environments for extended periods of time. For example, don't leave the batteries in your attic or in a sun room attached to your house.
