Prolong the life of your battery by using it more!
When your laptop is plugged into an outlet it is running from the primary power that is supplying the outlet. Lithium-ion laptop batteries go into standby mode when they are plugged in.
Exercise your battery by using your unplugged laptop at least once a week. Keeping your laptop plugged-in all the time will lead to a battery with shorter run-times and lower performance. Not using your battery is the most common reason lithium-ion batteries wear out.
Don't run your battery all the way to 0%
The second most common reason laptop batteries wear-out prematurely is that they are frequently discharged to empty. If a laptop battery runs below 3% it can damage the battery and may not continue to operate correctly.
Lithium-ion batteries last longer when they have shallow discharge and recharge cycles. It does not harm the battery to only use it for 5-10 minutes and then plug it back in. Rechargeable batteries will self-discharge when not in use.
Fully charge your laptop before first use
Your new battery comes in a discharged state for shipping. Recharge your laptop battery at least five times to get the full capacity and the best performance from the battery.
Recharge your battery before letting it get to 20%
Batteries last longer when they are plugged in at 20% battery life and are charged to at least 80%. This will maximize the life of your battery.
