ALL DATA IS SUBJECT TO CHANGE WITHOUT NOTICE

Issue No.: V.2 / Issue Date: Mar 2011

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

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

Batteries must not be suspended by their handles (where fitted)

Each cell is fitted with a low pressure release valve to allow gasses to escape and then reseal.

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