Battery 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 locations.
Do not charge a frozen battery because it can ex-
plode and cause injury. Let the battery warm to
o
F (16 C) before connecting to a charger.

o
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   battery   charger    manufacturer’s
instructions when using a battery charger.
NOTE:  Using specific gravity of the battery cells is the
most accurate method of determining battery condition.
