ACCU THERMO is the only battery on the market equipped with a safety exhaust valve.

The Safety Valve is located in the lower part of the casing and it protects the battery against damage

In the event of a Li-Ion battery pack failure, gas may be emitted and as a result, the battery casing may explode

The valve is maintenance-free and should not be disassembled. Do not interfere with the operation of the valve in any way.
