Precautions when recharging the battery
During recharging, the battery releases hydrogen. Therefore, remove the ventilation plugs before recharging.
If charging is performed while the battery is installed in the vehicle, be sure to disconnect the ground cable.
Make sure the power switch on the charger is turned off when connecting or disconnecting the charger cables from the battery.
Warning! Always charge the battery in an open area. Do not charge it in a garage or closed room without adequate ventilation.
