Cleaning
Keep battery clean by wiping it with a damp cloth. Keep
all electrical connections dry and tight. If corrosion is
present, disconnect cables from battery and remove
corrosion with a wire brush. Clean battery and cables
witha solutionof bakingsodaandwater. Becareful that
cleaning solutions do not enter battery cells. When
cleaningiscomplete,flushbatteryandcableswithclean
water and wipe with a dry cloth. After the battery cables
are reconnected, coat terminals with petroleum jelly or
other non-conductive grease.
Checking Electrolyte Level
Check the level of electrolyte before each start-up.
Remove filler caps and check to see that electrolyte
level is up to bottoms of filler holes. Refill as necessary
with distilled water or clean tap water. DO NOT add
fresh electrolyte! Be sure filler caps are tight.
Checking Specific Gravity
Useabatteryhydrometertocheck thespecificgravityof
the electrolyte in each battery cell. While holding the
hydrometer vertical, read the number on the glass bulb
atthe top ofthe electrolyte level. Ifthe hydrometerused
does not have a correction table, use the one in
Figure 3-16. Determine specific gravity and electrolyte
temperature of battery cells. Locate temperature in
Figure 3-16 and adjust specific gravity by amount
shown. The batteryisfullychargedifthe specificgravity
is 1.260 at an electrolyte temperature of 80°F (26.7°C).
The difference between specific gravities of each cell
should not exceed ± 0.01. The battery should be
charged if the specific gravity is below 1.215 at an
electrolyte temperature of 80°F (26.7°C).
