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 **Recycling** YUASA's VRLA batteries must be recycled at the end of life in accordance with local and national laws and regulations ~~ee~~
