Inspection, Maintenance, and Testing (Fig. 12)
1.
Perform following inspections and maintenance:
A. Check for cracks caused by overly tight hold–
down clamp. Replace battery if cracked and leak-
ing.
MAX. FILL
DO NOT OVERFILL
MIN. FILL
B. Check battery terminal posts for corrosion. Use
a terminal brush or steel wool to clean corrosion
from the battery terminal posts.
IMPORTANT: Before cleaning the battery, tape or
block vent holes to the filler caps and make sure the
caps are on tightly.
TORO
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 battery case for dirt and oil.
Clean the battery with a solution of baking soda and
water, then rinse it with clean water.

C. If the difference between the highest and lowest
cell specific gravity is 0.050 or greater or the lowest
cell specific gravity is less than 1.225, charge the
battery. Charge at the recommended rate and time
given in Charging or until all cells specific gravity is
or greater with the difference in specific grav-
ity between the highest and lowest cell less than
If these charging conditions can not be met,
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 between the minimum and
maximum fill lines. Charge at 15 to 25 amps for 15
minutes to allow sufficient mixing of the electrolyte.

A. Measure the specific gravity of each cell with a
hydrometer. Draw electrolyte in and out of the
hydrometer barrel prior to taking a reading to warm–
up the hydrometer. At the same time take the tem-
perature of the cell.

Follow the manufacturer’s instructions when us-
ing a battery tester.
