BATTERY RECHARGING
PRECAUTIONS
During recharging, the battery is producing hydrogen
gas.
Therefore, before recharging:
1. Maintenance type batteries ± Remove the vent plugs.
2. If recharging with the battery installed on the vehicle, be
sure to disconnect the ground cable.
3. Make sure the power switch on the recharger is off when
connecting the charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an unconfined area. Do not
charge the battery in a garage or closed room where there
is not sufficient ventilation.
Non±maintenance batteries: Only do a slow charge (5 A or
less). Charging at a quicker rate is dangerous. The battery
may explode causing personal injuries.
Maintenance type batteries: Be sure to remove the vent
plugs before recharging.
