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.
CAUTION
After battery has been in service,
add only approved water. DO NOT
ADD ACID.
TO INSTALL BATTERY
To install the battery in this unit, refer to
next column.
C. MAINTENANCE
1. Check periodically (every two weeks or before
and after charging) to be sure electrolyte
level is 9/16” above separator plates. Add
only distilled water or good quality drinking
water. NEVER add additional 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 electro­
lyte 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 usihg 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
occurs first.

3. Recharge battery whenever the specific
gravity is less than 1.225 before returning to
service or every two months, whichever
occurs first.
COMMON CAUSES FOR BATTERY FAILURE
ARE:
1. Overcharging
2. Undercharging
3. Lack of water
4. Loose hold downs and/or corroded
connections
5. Excessive loads
6. Battery electrolyte substitutes
7. Freezing of electrolyte
