PERFORMANCE & CHARACTERISTICS

Batteries must not be suspended by their handles (where fitted)
Vent valves
Each cell is fitted with a low pressure release valve to allow gasses to escape and then reseal.
Gas Release

VRLA Batteries release hydrogen gas which can form explosive mixtures in air. Do not place inside a sealed 
container
