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.
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. AGM & GEL
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 table below
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.
