CHECKING BATTERY SPECIFIC GRAVITY
Use a hydrometer to check the battery specific
gravity.
CHECKING GRAVITY
A. Hydrometer
B. Battery
NOTE: Do not take readings immediately after
adding distilled water, if the water and acid are not
thoroughly mixed, the reading may not be
accurate.
Check the hydrometer readings against this chart.

BATTERY CONDITION
1.265 100% CHARGED
1.225 75% CHARGED
1.190 50% CHARGED
1.155 25% CHARGED
1.120 DISCHARGED
NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 80°F
(27°C), the reading must be temperature
corrected.
To find the corrected specific gravity reading
when the temperature of the battery electrolyte is
other than 80°F (27°): Add (+) to the specific
gravity reading 0.004 (4 points), for each 10°F
(6°C) above 80° (27°C).
Subtract (-) from the specific reading 0.004 (4
points), for each 10°F (6°C) below 80°F (27°C).
TO CHARGE THE BATTERIES
When servicing machine, avoid contact with
battery acid.
Batteries emit hydrogen gas. Explosion or fire
can result. Keep sparks and open flame away.
Keep covers open when charging.
Wear eye protection and protective clothing
when working with batteries.
Charge batteries in a well ventilated area. Leave
the solution tank open.
Use a 24 volt, 20 amp maximum output, DC charger
