Flooded Lead-Acid Batteries:


Flooded lead-acid batteries must be kept in an upright position at all times. The electrolyte in a flooded battery may spill if tilted more than 20 degrees.


VRLA AGM & GEL Batteries:


Rolls VRLA AGM & OPzV GEL batteries may not be mounted upside down or horizontally on the end (shortest side of the case). 

Rolls VRLA AGM batteries may be installed on the side (longest side) when required.  However, Rolls recommends installing upright for best performance.


Rolls OPzV GEL models must be installed vertically unless otherwise specified. Special order models compatible with horizontal installation are available. Use caution not to cover or apply pressure to valves located on the top of the batteries when using strapping to install or secure cells as damage may occur.

Rolls OPzV GEL models compatible with horizontal installation as well as racking systems are available upon request. Please contact your Rolls Battery distributor or dealer for more information.
