3-3.5. MAINTENANCE FREE BATTERIES

Some trucks may be equipped with maintenance free
batteries. These batteries are completely sealed, will
not require any watering and have a full 80% dis-
charge available.
Sealed Maintenance Free batteries contain a pressure
release valve and under normal operating conditions
do not require any special ventilation.
CAUTION: Do not try to open this battery or remove
the pressure release valve.
Only under severe overcharging, such as connected
to an improperly sized charger, will any significant
amount of gasses be released from the battery. Also,
being a valve regulated battery, it never requires
watering.

placing a battery on charge.
Proceed as follows:

teries. Contact appropriate personnel for repairs
to be made.
3. Disconnect the batteries from the truck and con-
nect the batteries to the charger. Make sure con-
nectors are mated properly.
4. Connect the charger to the appropriate power
supply.
