nitecore 14500 3.7v 750mah

NL1475R MicroUSB - Protected Rechargeable Li-Ion 14500 Battery 3.6V 750mAh The new Nitecore NL1475R is a revolutionary 14500 battery: it is in fact designed with a built-in micro-USB charging port so that it can be recharged directly using a standard micro-USB charging cable (sold separately). Simply connect the battery to an available USB power source (for example a PC or a wall charger for a tablet or smartphone) and a red light next to the positive terminal of the battery will turn on to let you know that the charging process 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 14500 batteries. Equipped with integrated intelligent charging circuits and other safety features, this battery is completely safe to operate if you respect the indicated precautions.
