Inspection, Maintenance, and Testing
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 bat•
tery. Charge at the recommended rate and time giv•
en in Charging or until all cells specific gravity is

Perform the following inspections and maintenance:
A. Replace battery if cracked or leaking.

between the highest and lowest cell less than 0.050.
If these charging conditions can not be met, replace
the battery.
IMPORTANT: Before cleaning the battery, tape or
block vent holes to the filler caps and make sure the
caps are on tightly.
3.
Perform a high–discharge test with an adjustable
load tester.
C. Check for signs of wetness or leakage on the top
of the battery which might indicate a loose or missing
filler cap, overcharging, loose terminal post, or over•
filling. 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.
This is one of the most reliable means of testing a battery
as it simulates the cold–cranking test. A commercial bat•
tery load tester is required to perform this test.
CAUTION
D. Check that the cover seal is not broken away. Re•
place the battery if the seal is broken or leaking.
Follow the battery tester manufacturer’s instruc•
tions when using a battery tester.
E. Check the electrolyte level in each cell. If the level
is below the tops of the plates in any cell, fill all cells
with distilled water between the minimum and max•
imum fill lines. Charge at 15 to 25 amps for 15 min•
utes to allow sufficient mixing of the electrolyte.
A. Check the voltage across the battery terminals
prior to testing the battery. If the voltage is less than
12.4 VDC, recharge the battery.
2.
Conduct a hydrometer test of the battery electrolyte.
B. If the battery has been charged, apply a 150 amp
load for 15 seconds to remove the surface charge.
Use a battery load tester following the manufactur-
er’s instructions.
IMPORTANT: Make sure the area around the cells is
clean before opening the battery caps.
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.
C. Make sure battery terminals are free of corrosion.
D. Measure the temperature of the center cell.
E. Connect a battery load tester to the battery termi•
nals following the battery tester manufacturer’s
instructions. Connect a digital multimeter to the
battery terminals.
B. Temperature correct each cell reading. For each
10
oF (5.5oC) above 80oF (26.7oC) add 0.004 to the
specific gravity reading. For each 10oF (5.5oC) be•
low 80oF (26.7oC) subtract 0.004 from the specific

mance (see Battery Specifications) rating of the bat•
