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-
nectingthechargerleadsfromthebattery
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.

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 125o F (51.6o 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
