## Safety 

## **Installation** 

Can be installed and operated in any orientation except permanently inverted. 

## **Handles** 

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 the 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.
