4. OPERATION
Batteries are rated in ampere-hours (Ahr) and are selected to perform a specific workload within an
established period of time. Increasing the workload or time period could result in over discharging, thus
shortening battery life. Limit discharging of the battery (to 80% or less) so that specific gravities do not
go below 1.180. If truck operation results in only partial discharges (40% or less) and specific gravities
are 1.250 or more at the end of the shift, recharging may be deferred and the battery used for another
shift, providing the workload is not expected to increase. Hydrometer readings and experience will
determine the frequency of charge intervals under these circumstances.
A battery should always be recharged immediately following a complete discharge. Never allow it to
remain in a discharged condition; otherwise, permanent damage may result. A battery is designed to
be operated as follows:
8 hours discharge
8 hours charge
8 hours cool-down
Tubular-LM Low Maintenance batteries are designed and built to deliver 80% of their rated capacity at
77°F (25°C) each cycle.
5. TEMPERATURE
In the operation of motive power lead acid batteries, the electrolyte temperature must not exceed
110°F (43°C). If the battery is continuously operated at or above this temperature, the service life of
the battery will be severely diminished. Under normal operating conditions, battery electrolyte
temperature should be maintained between 60-100°F (15-38°C). Following charging, the battery
should be allowed to cool-down or rest approximately 8 hours prior to another discharge cycle.
If a battery is ever hot to the touch, allow it to cool to room temperature before charging or discharging.
If a battery consistently operates at high temperatures greater than 100°F (38°C), contact your local
GNB Industrial Power representative for service.
6. CHARGING
The battery should be charged exclusively with the charger provided with the system.
WHEN BATTERY RECHARGE IS REQUIRED, PLUG THE BATTERY CABLE CONNECTOR
INTO THE CHARGER CABLE CONNECTOR AND THEN PLUG THE 3-PRONG CHARGER
POWER CORD INTO A GROUNDED 120 VOLT 15 AMP 50 HZ OR 60 HZ POWER OUTLET.
The charger is equipped with an LED indicator to show the progress of the charging cycle.
RED LED shows that the battery is in the initial charging phase.
YELLOW LED shows that the battery has reached 80% of charge.
GREEN LED shows that the battery has reached 100% of charge.
