Exide Technologies GB4146 - Manual (Page 3)

Following the first month of service, the battery should reach its normal operating specific
gravity of 1.305 +/- 0.005 at 77° F.
4. OPERATION
Batteries are rated in ampere-hours (Ah) and are selected to perform a specific
workload within an established period of time. Because fast charge systems are
designed to return a significant amount of ampere-hours in short periods of time, fast
charge batteries are capable of delivering up to 160% of their rated capacity within a
24-hour period. To achieve such high levels of usage, operators must be diligent to
"plug in" at all opportunities throughout the day, including breaks, meals, and shift
changes. Care must be taken to ensure specific gravity readings in the battery cells do
not go below 1.160 at any time.
A Tubular-HP or Tubular-LM Fast Charge Battery is designed for fast charging during
breaks, meal times, and shift changes. When not being used, the battery should
always be connected to the charger. The battery must be limited to no more than
twenty (20) hours of use per day, six days per week, and 50 weeks per calendar year.
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.
Flooded tubular-plate motive power batteries are designed and built to deliver 80% of
their rated capacity at 77° F.
5. TEMPERATURE
In the operation of fast charge lead-acid batteries, the electrolyte temperature must never
exceed 140°F or a 7-day average temperature of 125°F. Following the end of the day full
charge, the battery should be allowed to cool to ambient temperature prior to the next
discharge.
The average electrolyte temperature of the battery shall not drop below 60°F (15°C).
If a battery consistently operates at temperatures close to the allowable maximums,
contact your local GNB representative for service.

IF BATTERIES ARE NOT IN USE, KEEP THEM CHARGED.
CHECK THE SPECIFIC GRAVITIES MONTHLY AND GIVE A FRESHENING CHARGE
(3 OR 4 HOURS AT THE FINISH RATE) IF THE GRAVITIES HAVE FALLEN 0.030 OR
MORE; OTHERWISE GIVE A FRESHENING CHARGE EVERY THREE MONTHS.
