A When the battery is being activated, hydrogen
and oxygen gases in the battery are extremely
explosive. Keep open sparks and flames away
from the battery at all times, especially when
charging the battery.
A When charging the battery, ensure the vent
caps are securely in place. (if equipped)
A When disconnecting the cable from the battery,
start with the negative terminal first.

1. To slow charge the battery, connect the battery
positive terminal to the charger positive terminal and
the negative to the negative, then recharge in the
standard fashion.
