Charging
To minimize possible damage to the battery and allow
the battery to be fully charged, the slow charging meth-
od is presented here. This charging method can be ac-
complished with a constant current battery charger
which is available in most shops.
CAUTION
Follow the manufacturer's
when using a battery charging.
1. Determine the battery charge level from either its
open circuit voltage or specific gravity.

100% 12.68
75% 12.45
50% 12.24

2. Determine the charging time and rate using the
manufacturer's battery charger instructions or the
following table.

CAUTION
Do not charge a frozen battery because it
can explode and cause injury. Let the bat-
tery warm to 60 F (15.5 C) before con-
necting to a charger.
Charge the battery in a well–ventilated
place to dissipate gases produced from
charging. These gases are explosive;
keep open flame and electrical spark
away from the battery. Do not smoke.
Nausea may result if the gases are in-
haled. Unplug the charger from the elec-
trical outlet before connecting or discon-
necting the charger leads from the battery
posts.
3. Following the manufacturer's instructions, con-
nect the charger cables to the battery. Make sure a good
connection is made.
4. Charge the battery following the manufacturer's
instructions.
5. Occasionally check the temperature of the battery
electrolyte. If the temperature exceeds 125 F (51.6 C)
or the electrolyte is violently gassing or spewing, the
charging rate must be lowered or temporarily stopped.
6. Three hours prior to the end of the charging, mea-
sure the specific gravity of a battery cell once per hour.
The battery is fully charged when the cells are gassing
freely at a low charging rate and there is less than a
0.003 change in specific gravity for three consecutive
readings.
