To minimize possible damage to the battery and to allow
the battery to be fully charged, the slow charging method
is presented here. This charging method can be accom-
plished with a constant current battery charger which is
available in most shops.

NOTE: Using specific gravity of the battery cells is the
most accurate method of determining battery condition.
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.
1.
If battery filler caps are removable, check the electro-
lyte level in each cell. If the level is below the tops of the
plates in any cell, fill all cells with distilled water so that
plates are just covered with electrolyte.
2.
Determine the battery charge level from either its
open circuit voltage or specific gravity (if filler caps are
removable).
4. Following the manufacturer’s instructions, con-
nect the charger cables to the battery. Make sure a good
connection is made.

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.

Three hours prior to the end of the charging, measure
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 read-
ings.
