Using the Car Battery Charger CBC-NB2
Car Battery Charger CBC-NB2 (sold separately) can be used to charge
battery packs from an automobile's cigarette lighter socket.
Always ensure that the automobile's engine is running when you use
the car battery charger. Use of it with the engine off may flatten the
battery. Always unplug the car battery charger before turning off the
engine.
The battery will stop charging whenever you turn the engine
off, so be sure to unplug the car battery cable from the
cigarette lighter socket.
Wait until the engine is running again to plug the car battery
cable into the cigarette lighter socket.
The car battery charger can only be used in a negative
ground car. It cannot be used in a positive ground car.
