Yard-Man 13875-9 - Activating the Battery

B. Neutralize acid spilled on clothing with dilute
ammonia water or a water solution of baking
soda. If acid gets on clothes, dilute It with
clean water first, then neutralize.
C. If for any reason acid should be spattered in
the eyes, wash it out Immediately with clean
cold water. Seek medical aid if discomfort
continues.
D.
Since battery acid is corrosive to metals, do
not pour into any sink or drain. Rinse empty
electrolyte containers and mutilate before
discarding.

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.

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.
B. TO INSTALL BATTERY
To install the battery in this unit, refer to page
7.
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.
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 V 2 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 rale in excess of this will buckle and
warp the positive plates and perforate the
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.
E. COMMON CAUSES FOR BATTERY FAILURE
ARE:
1. Overcharging
2. Undercharging
3. Lack of water
4. Loose hold downs and/or corroded con¬
nections
5. Excessive loads
