Installation Manual

GEL BATTERY INSTALLATION & CHARGING

Designed and well-suited for regular cycling as well as float and backup

applications, Rolls sealed OPzV GEL batteries have a low internal resistance

allowing quick recharge and a low self-discharge rate (less than 2% per

month). OPzV GEL batteries perform well in high cyclic use even under extreme

operating conditions and offer more than 20 year cycle life in float applications

at 25ºC / 77ºF.

INSTALLATION

Rolls GEL batteries may be mounted upright or horizontally on the side (longest)

of the battery case. Use caution not to cover valves located on the top of the

batteries when using strapping to secure as damage may occur. Rolls GEL

batteries may not be mounted upside down or horizontally on the end (shortest

side) of the case.

Racking systems are available. Contact your Rolls Battery Distributor or Dealer

for options and availability.

GEL BATTERY CHARGING

Rolls GEL sealed VRLA batteries have very similar installation and maintenance

requirements as Rolls sealed AGM product lines, with the exception of unique

charge and float voltages. Although they are a sealed battery, ventilation is still

required to avoid risk of off-gassing and explosion and general battery cleaning

and maintenance should be followed.
