ELECTRICAL SYSTEM 17-23
Battery
Ordinary Charging
WARNING
Keep the battery away from sparks and open flames
during charging, since the battery gives off an ex-
plosive gas mixture of hydrogen and oxygen. When
using a battery charger, connect the battery to the
charger before turning on the charger. This proce-
dure prevents sparks at the battery terminals w hich
could ignite any battery gases.
CAUTION
Always remove the battery from the vehicle for
charging. If the battery is charged while still in-
stalled, battery electrolyte may spill and corrode
the frame or other parts of the vehicle.
Charging the battery at a rate higher than specified
may ruin th e battery. Charging at a high rate causes
excess heat which can warp the plates and cause
internal shorting.
Higher-than-normal charging rates also cause the
plates to shed active material. Deposits will accu-
mulate, and can cause internal shorting.
If the temperature of the electrolyte rises above
45°C (113°F) during charging, reduce the charging
rate to lower the temperature, and increase charg-
ing time proportionately.
Remove the battery (see Battery Removal).
NOTE
Neverattempttochargeafrozenbattery.
Allow it to warm up to room temperature before charg-
ing.
Never leave a battery on a trickle charger longer than
48 hours. Serious damage to the battery will occur.
(Conventional Type Battery)
Charge the battery with a current of 1 to 1.5 amps until the
specific gravity rises to 1.250 and temperature reaches
15.5°C (60°F).
Refer to the Battery Charging Time Table for the charging.
