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 protects the battery against damage.

In the event of a Li-Ion battery pack failure, gas may be emitted, which could cause the battery casing to explode.

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