,' t DANGER *-.~.
C.
MAINTENANCE
1. Check periodically (every two weeks or
before and after charging) to be sure elec-
trolyte level is 9/16" above separator
plates. Add only distilled water or good
quality drinking water. NEVER add addi-
tional acid or other chemicals to battery
after initial activation.
2. The battery should be checked with a
hydrometer after every 25 hours of
operation. If the specific gravity is less than
1.225 remove battery and recharge.
3. Coat the terminals and exposed wiring with
a thin coat of grease or petroleum jelly for
longer service and protection against
electrolyte corrosion.
4. The battery should be kept clean. Any
deposits of acid should be neutralized with
soda and water. Be careful not to get this
solution in the cells.
D. STORAGE
1. Charge battery using normal methods.
NEVER store discharged battery as it will
not recover.
2. Store in cold, dry place.
3. Recharge battery whenever the specific
gravity is less than 1.225 before returning to
service or every two months, whichever
comes first.
BATTERIES CONTAIN SULFURIC
ACID AND MAY CONTAIN EXPLO-
SIVE GASES (when electrolyte has
been added)A.
Keep sparks, flame, cigarettes away.
B. Hydrogen gas is generated during charging
and discharging.C.
Ventilate when charging or using in enclosed
space.
D. When using a charger-to avoid sparks,
NEVER connect or disconnect charger clips to
battery while charger is turned on.
E. Always shield eyes, protect skin and clothing
when working near batteries.
ACTIVATING THE
BATTERY
1. Place battery to be filled on bench or
workbench. NEVER activate battery in unit.
Remove vent caps from all cells.
2. Fill each cell carefully using battery grade
1.250-1.265 specific gravity. Sulfuric acid to
be 3/8" above the top of the separators or to
split ring.
3. Allow battery to set for 20 minutes to V2 hour.
Add additional acid if necessary to bring it up
to the proper level.
4. Replace the vent caps.
5. The battery can now be charged after the 20
minutes setting period. Battery can be SLOW
CHARGED (DO NOT FAST CHARGE) at a
maximum bench rate of 4-5 amperes until the
specific gravity reading is 1.265-1.275. A
charging rate in excess of this will buckle and
warp the positive plates and perforate the
separators. If electrolyte bubbles violently
while charging, reduce charging rate until
excessive bubbling action subsides, then
continue charging until specific gravity is
reached.
E.
COMMON CAUSES FOR BATTERY FAILURE
ARE:
1. Overcharging
2. Undercharging
3. Lack of water
4. Loose hold downs and I or corroded con-
nections
5. Excessive loads
6. Battery electrolyte substitutes
7. Freezing of electrolyte
NOTE
THESE FAILURES DO NOT CON-
STITUTE WARRANTY.
~ CAUTION
After battery has been in service,
add only approved water. DO NOT
ADD ACID.
B. TO INSTALL BATTERY
