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 explode and cause injury. Let the bat-
tery warm to 60o F (15.5o C) before con-
necting to a charger.
CAUTION
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.
Follow the manufacturer’s instructions when
using a battery charger.
1.
Determine the battery charge level from either its
open circuit voltage or specific gravity.

4.
Charge the battery following the manufacturer’s
battery charger instructions.
5.
Occasionally check the temperature of the battery
electrolyte. If the temperature exceeds 125o F (51.6o C)
or the electrolyte is violently gassing or spewing, the
charging rate must be lowered or temporarily stopped.
2.
Determine the charging time and rate using the
manufacturer’s battery charger instructions or the
following table.
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
