INSTALLATION

Rolls deep cycle batteries are manufactured for use in a wide variety of

applications. No matter the use, it is important that the battery is installed

securely, free of contaminants and that all connections are in good contact

with the terminals. Excessive heat or cold temperatures will result in the

reduction of the overall life of your batteries.

Flooded batteries should be installed in a temperature-controlled room or in

an enclosure that insulates the batteries from freezing or overheating. Batteries

should never be installed in a completely sealed cabinet. Valve regulated battery

enclosures should at minimum be passively ventilated, while enclosures for

flooded models should be actively ventilated with both positive and negative flow

installed to remove and replace hydrogen gas generated during charging (as cell

voltage reaches 2.25 VPC or above). Hydrogen concentration in excess of 2-4%

is explosive. Every effort should be made to avoid hydrogen accumulation. For

all Rolls battery models it is recommended that batteries are separated 2.5cm-

7.5cm (1”-3”) inches apart to allow for ease of maintenance and proper airflow

and cooling.

BATTERY ORIENTATION

Flooded lead acid batteries must be kept in an upright position at all times.

Electrolyte in the battery may spill if tilted more than 20 degrees.

Rolls VRLA AGM & 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 VRLA

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

of the case.

CABLE SIZING

Cabling should be proportionate to the amperage of your system. The following

table notes the maximum current carrying capacity based on cable gauge.

Battery cabling should be selected allowing a maximum voltage drop of 2% or

less across the entire length of the cable. Interconnection cables (battery to

battery) should also be sized at the same gauge and of equal length between

connections.
