How to care for the battery?

-If you do not use your laptop for extended periods of time (a week or more), remove the battery pack from the laptop.-Do not expose the battery to high heat or freezing temperatures. Do not leave your battery in your car in the summer. Hot batteries discharge very quickly, and cold ones can’t create as much power.-Completely drain and recharge the battery overnight once a month to maximize its capacity to hold a charge.-Fully charge new battery packs before use. New pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.-For laptops that work as Desktop Replacement, the battery should be re-installed every 3-4 weeks and allowed to fully discharge.-Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.
