Use battery Skills:

Before use the new battery, we suggest that all of our customers should fully charge it by AC power adapter.Because maybe it takes a long period, the capacity was strain
out by inner PCB circuit.In order to protect your battery life, you can fully charge it to 100% and drain to 3% 2 times, then the capacity will recover. The suggestion is to
charge the battery regularly once a month. it's good for extending the battery life
