Remarkable about this 16340 battery is that you don't need a charger. A micro-USB cable is enough. This battery namely contains a micro-USB port in order to charge it. The head of the battery contains a small LED light. It will show you the charging status. It is important to know that this battery is protected from over and undercharging with the help of a protective circuit. Please note: if you want to charge the battery via the micro-USB port you need a power source that supplies you with a maximum of 500mAh (0.5 Amps). As soon as you charge the battery in the charging station we recommend an output of up to 1000mAh.
