ROLLS OPzV 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 than Flooded deep
cycle models allowing quick recharge and a low self-discharge rate (2% per month).
Rolls OPzV GEL batteries perform well in installations requiring frequent cycling even
under extreme operating conditions and offer more than 20 year cycle life in float
applications at 25ºC (77ºF).
INSTALLATION
Rolls OPzV GEL batteries should be installed upright unless otherwise specified and
should not be mounted upside down or horizontally on the end (shortest side) of the
case. Models compatible with horizontal installation (longest side) as well as custom
racking systems are available upon request. Contact your Rolls Battery Distributor
or Dealer for more information.
Use caution not to cover or apply pressure to valves located on the top of the batteries
when using strapping to move or secure the batteries as damage may occur.
OPzV GEL BATTERY CHARGING
Rolls OPzV GEL batteries have similar installation and charging requirements as VRLA
AGM models with the exception of unique Bulk, Absorption and Float voltage set points.

NOTE: Use the highlighted voltage set points when charge equipment is supplied with
a temperature sensor. Set at 3mV/ºC/Cell...(+/- 72mV per ºC from a 25ºC Delta
- 48V System) Higher or lower settings may cause incorrect adjustments in charge
voltage. Without a temperature sensor, charge settings must be adjusted manually
based on the battery temperature when in use, not just ambient temperatures.
