RECEIVING BATTERIES
Immediately upon receipt of shipment, examine the outside of the packing for signs of rough handling
before accepting the battery from the carrier. Wet spots on the shipping pallet may be an indication
of leaking jars broken in shipment.
If there is evidence of damage, the receipt should be signed and both copies (carrier’s and receiving
copies) marked “Shipment Received Damaged”. The carrier should be called immediately and asked
to make a “Carrier’s Inspection for Damage Report”.
If “concealed” damage is later detected, the carrier should be called immediately and requested
to make a “Carrier’s Inspection for Concealed Damage Report”. After inspection by the carrier,
arrangements should be made with the local GNB
®
Industrial Power representative to have the battery
repaired before placing it in service.
BEFORE PLACING BATTERIES IN SERVICE,
REVIEW AND FOLLOW THE SAFETY GUIDELINES LISTED IN SECTION 1.

PLACING IN SERVICE
Verify that the battery weight meets or exceeds the minimum truck weight requirements. Allow the
battery to cool or warm to room temperature before charging or adding water. Make sure the battery
charger is properly matched to the battery. Use a charger with automatic charger termination controls.
GNB recommends the use of an SCR charger with an I-E-I charging profile in order to achieve
a minimum 45-day watering interval. To achieve a minimum 90-day watering interval, GNB
requires the use of a GNB
®
charger with a Tubular-LMX™ charging profile.
Open the vent caps from each cell and check to see that the electrolyte level is above the plate
separators. If it is obvious that the electrolyte has spilled out of any cells, replace it with electrolyte
of the same specific gravity as found in the other cells of the battery (1.280 – 1.290). Close the vent
caps and give the battery a freshening charge until there is no increase in specific gravity for three
hydrometer readings taken at one-hour intervals.
During shipment of the battery, low temperatures and/or normal shock and vibration often results in
a drop in the electrolyte level. If the level is below the plate separators, recheck it after 3 hours of
charging. If the level remains below the plate separators, add water or electrolyte to the proper level
at the end of charging.
Following the first 90 days of service, the battery should reach its normal operating specific gravity of
1.295 to 1.345 at 77° F (25° C).
BEFORE PLACING BATTERIES IN SERVICE,
REVIEW AND FOLLOW THE SAFETY GUIDELINES LISTED IN SECTION 1.
IF BATTERIES ARE NOT IN REGULAR USE, KEEP THEM CHARGED.
CHECK THE SPECIFIC GRAVITIES MONTHLY AND GIVE THE BATTERY 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.
