Use battery Tips:
Your new battery has a basic charge and in order to protect your battery life, please use it until it has discharged almost completely (10%15%), then recharge it completely. Do this 3-5 times to activate the batterys maximum capacity.
We suggest that charge the battery regularly once a month even under not used situation. If you remove battery for a long time, charge more than 80% at least one time within one months or fully charge it by AC power adapter. it's good for extending the battery life. When using the battery, care should be taken to prevent exposure and moisture.
