Battery Service

The battery is the heart of the electrical system. With
regular and proper service, battery life can be extended.
Additionally, battery and electrical component failure
can be prevented.
Note: Battery information for all Groundsmaster
322/325 machines and Groundsmaster 345 machines
with serial number below 21000000 is included in Chap-
ter 6.

CAUTION
Wear safety goggles and rubber gloves
when working with electrolyte. Charge
the battery in a well ventilated so gases
produced while charging can dissipate.
Since the gases are explosive, keep open
flame and electrical spark away from the
battery; do not smoke. Nausea may
result if the gases are inhaled. Unplug
charger from electrical outlet before con-
necting to, or disconnecting charger
leads from battery posts.

Inspection, Maintenance and Testing
1. Perform the following inspection and maintenance
tasks:
A. Check for cracks caused by overly tight or loose
hold–down clamp. Replace battery if cracked and
leaking.
B. Check battery terminal posts for corrosion. Use
a terminal brush to clean corrosion from the battery
terminal posts.
IMPORTANT: Before cleaning the battery, tape or
block the vent holes to the filler caps and make sure
the caps are on tightly.

C. Check for signs of wetness or leakage on the top
of the battery which might indicate a loose or mis-
sing filler cap, overcharging, loose terminal post or
overfilling. Also, check the battery case for dirt and
oil. Clean the battery with a solution of baking soda
and water, then rinse it with clean water.
D. Check that the cover seal is not broken away.
Replace the battery if the seal is broken or leaking.
E. Check the electrolyte level in each cell. If the lev-
el is below the tops of the plates in any cell, fill all
cells with distilled water to the bottom of the cap
tubes. Charge at 15 to 25 amps for 15 minutes to al-
low sufficient mixing of the electrolyte.
