HOW TO CHARGE THE BATTERY
WARNING
DO NOT put tools on the battery.
If the lift truck was operated with a low battery,
check all contactors for welded contacts before
a charged battery is connected.
Make sure the key switch is in the OFF position
and the park brake is set before connecting the
battery.
The acid in the electrolyte can cause injury.
If the electrolyte is spilled, use water to flush
the area. Use a solution of sodium bicarbon-
ate (soda) and water to make the acid neutral.
Acid in the eyes must be immediately flushed
with water continuously for 15 minutes, then
seek medical attention.
Batteries generate explosive fumes. Keep the
vents in the caps clean. Keep sparks or open
flames away from the battery area. DO NOT
make a spark from the battery connections.
Disconnect the battery when doing mainte-
nance.
CAUTION
Never connect the battery charger plug to the
plug of the lift truck.
You can damage the
electronic controller. Make sure the battery
charger voltage is the correct voltage for the
battery.
Correct use of the hydrometer and proper operation
of the battery charger is important.
Operate the
battery charger according to the instructions of
the charger manufacturer.
Never let the battery
discharge below the minimum value given by the
battery manufacturer. A fully charged battery will
have a specific gravity of 1.265 to 1.310 at 25 C
(77
F)
. See Table 1. Never charge a battery at a rate
that will raise the electrolyte temperature above
49 C (120
F)
. Never permit a battery to stay dis-
charged for long periods.

Equalizing Charge
This charge is at a low rate and balances the charge
in all of the cells. The equalizing charge is normally
given approximately once a month. It is a charge at
a slow rate for 3 to 6 hours in addition to the regular
charging cycle.
DO NOT give an equalizing charge more than once
a week. The most accurate specific gravity measure-
ment for a charged battery will be after an equalizing
charge. If the difference in specific gravity is more
than 0.020 between cells of a battery after an equal-
izing charge, there may be a cell that has a malfunc-
tion. Consult your battery dealer.
NOTE:
Many customers have battery chargers that
can follow a program to automatically charge a
battery according to recommendations of the bat-
tery manufacturer.
Use the recommendations of
the battery manufacturer for charging the battery.
Use only battery chargers approved by the battery
manufacturer or dealer.
Normal Charge
This charge is normally given to a battery that is
discharged from normal operation. Many customers
charge the battery at regular intervals that depend
on use. This procedure will keep the battery correctly
charged if the battery is not discharged below the
limit. Always use a hydrometer to check the battery
if the battery is charged at regular intervals. Fre-
quent charging of a battery that has a 2/3 or more
charge can decrease the life of the battery.
