21700

You can recharge it normally by inserting it into a battery charger or recharge it like a cell phone: by inserting a USB-C cable!

The new Nitecore NL2153R is a revolutionary 21700 battery: it is designed with an integrated USB-C charging port so that it can be recharged directly using a USB charging cable (sold separately).

Simply connect the battery to an available USB power source (e.g., a PC or wall charger for tablets or smartphones) and a red light next to the positive pole of the battery will turn on to let you know that charging has begun. Once the light turns green, charging is complete.

Alternatively, these batteries can be charged normally, like any rechargeable battery, using any external charger compatible with Li-Ion 21700 batteries.

Equipped with integrated smart charging circuits and other safety features, this battery operates safely when used in accordance with the precautions indicated.
