INSTALLATION
Rolls deep cycle batteries are manufactured for use in a variety of applications. In all
cases, it is important that the battery is installed securely, free of contaminants and
that all connections are in good contact with the terminals.
For all Rolls models it is recommended that the batteries are separated 2.5cm-7.5cm
(1"-3”) inches apart to allow proper airflow, cooling and ease of maintenance. Flooded
batteries should be installed in a temperature-controlled room or enclosure with
adequate battery spacing to allow cooling and/or insulating to prevent freezing in very
cold temperatures. Excessive heat or cold temperatures will result in the reduction of the
overall cycle life. Batteries should never be installed in a completely sealed enclosure.
Enclosures for Valve Regulated batteries (VRLA such as sealed AGM & GEL models,
should, at minimum, be passively ventilated. Enclosures for Flooded models should
be actively ventilated with both positive and negative airflow installed to remove and
replace any hydrogen gas generated during charging (produced as cell voltage reaches
2.25 VPC or above. Every effort should be made to avoid hydrogen accumulation as
concentrations in excess of 2-4% may ignite with electrical spark and are explosive.
The outer container of Rolls Series 5000 models is molded with handles to safely lift
and transport the battery. This also provides structural support to maintain cell shape
and offers an added layer of protection. Rolls individual 2V industrial cells are typically
housed in steel or plastic trays. These cells must be properly supported on each side
to protect against puncture, prevent bulging and should not be lifted by the terminals
as this may damage the posts or compromise the cells internally. When moving,
support straps should be used to safety and securely lift the cell from the bottom.
Dual-container models are better-suited and strongly recommended over industrial
cells for use in Renewable Energy and Marine applications as the stand-alone case
design allows easier transport and the ability to install the batteries with adequate
spacing for airflow. Series 5000 dual-container models are backed by a 5-year
(60 month) full replacement warranty, offering an additional 2 years of coverage over
the equivalent 2V industrial cell.
BATTERY ORIENTATION
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. 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 mounted upright or horizontally on the side (longest
of the battery case. 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.
