The micro-USB rechargeable Li-Polymer 9V block with its own charging electronics is equipped with protection/PCB, short-circuit, overcharge and deep discharge protection. You can use the Li-ion battery just like other batteries in almost any device and without the usual self-discharge. All you need to charge it is a USB cable and a 5V USB 1A - 3A power adapter or 5V USB computer connector. (not included)9V block Li-ion battery ReadyToUse PCB protectedThe lithium-ion technology convinces with higher energy density, higher capacities and low self-discharge.

Damage, overcharging, deep discharging, excessive currents, operation at temperatures that are too high (above 60°C) or too low (below 0°C) and prolonged storage in a discharged state will damage or destroy the cell in most cases. For charging Lithium Ion batteries a special charger is required, which charges the batteries according to a special charging procedure. (CCCV = constant current, constant voltage.) or via the built-in Micro-USB input 5V 1A - 3A.
