Charging
CAUTION
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.
Do not charge a frozen battery because it can ex-
plode and cause injury. Let the battery warm to
_F (15.5_ C) before connecting to a charger.
60
Charge the battery in a well−ventilated place to
dissipate gases produced from charging. These
gases are explosive; keep open flame and elec-
trical spark away from the battery. Do not smoke.
Nausea may result if the gases are inhaled. Un-
plug the charger from the electrical outlet before
connecting or disconnecting the charger leads
from the battery posts.
CAUTION
Follow the manufacturer’s instructions when us-
ing a battery charger.
Note:
Using specific gravity of the battery cells is the
most accurate method of determining battery condition.
3. Following the manufacturer’s instructions, con-
nect the charger cables to the battery. Make sure a good
connection is made.
1.
Determine the battery charge level from either its
open specific gravity or circuit voltage.
4.
Charge the battery following the manufacturer’s
instructions.

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