Exide Technologies GB3914 - Manual (Page 2)

• Familiarize yourself with batteries and rules for
charging and handling. Contact your local GnB
representative for information.
• Assign battery and charger care to properly
trained personnel. Review your company safety
regulations, and familiarize yourself with industry
and government guidelines (OSHA, AnSI, etc.) to
help reduce personnel accidents and equipment
damage.
7. OPERATION
Batteries are rated in ampere-hour and are selected
to perform a specific workload within an established
period of time. Increasing the work load or time period
could result in over discharging, thus shortening battery
life. In general, all lead-acid batteries should not be
discharged to more than 80% of its six-hour rated
capacity. In a typical application, one battery is required
per truck per eight-hour shift. If a lift interrupt is used or
installed on the lift truck, a minimum interrupt voltage of
1.86 VPC multiplied by the number of cells, should be
set to avoid over discharge of the battery.
ADJUST LIFT INTERRUPT SETTING ON LIFT
TRUCK TO A MINIMUM INTERRUPT VOLTAGE
OF 1.86 VPC MULTIPLIED BY THE NUMBER OF
CELLS FOR ELEMENT BATTERIES
Since an ElEmEnT battery has unremovable vent
caps, its state of charge cannot be approximated by
specific gravity measurement. However, average cell
voltage (Volts per Cell) with the battery under load can
be used to approximate the battery depth of discharge
as shown in FIG. 1. Alternatively, the battery at 80%
depth of discharge will have an open circuit voltage
equal to 2.02 VPC multiplied by the number of cells in
the battery.
THE ELEMENT BATTERY SHOULD NOT BE
DISCHARGED BELOW 1.86 VOLTS PER CELL
(80% DEPTH OF DISCHARGE)
8. TEMPERATURE
normal operating conditions shall be between 60°F and
100°F. Operating temperature above 100°F will reduce
the battery’s service life. Operating temperature below
60°F results in less capacity and special charging is
required.
9. MAINTENANCE
Because this is a maintenance-free battery, there is
little to do regarding maintenance operations. The top
of the battery should be kept clean and dry and maybe
dusted to remove any accumulated foreign matter. In
the unlikely event of accidental contamination with
electrolyte, wash with a neutralizing solution (or one-
gallon water mixed with one pound of baking soda or
commercial soda ash). Follow with a rinse using clear
water. Ensure waste water is disposed of in accordance
with Federal, State and local regulations. Blow excess
water off the top of the battery using compressed air. In
the event of an accident involving a battery, notify your
local GnB representative who is equipped to handle
any environmental concern. never attempt to add water
to the battery - it has been designed to function without
any such additions over its entire life. As previously
noted, any attempt to remove the vent caps shall void
the warranty.
10. CHANGES IN OPERATIONS
If any time after initial purchase you have changes to
your operating conditions, such as extended shifts,
increased loads or other changes that alter your initial
purchase conditions, please contact your local GnB
representative immediately to ensure you are properly
equipped and are not affecting the life of the battery.
11. SERVICE
Additional information and assistance can be obtained
