Battery Precautions

^ Never use a booster/starter which has a voltage rating above 12 volts to start engine.

^ Always ensure the battery is properly connected to the vehicle prior to attempting to start engine.

^ Don't disconnect the battery when the engine is running.

^ When charging a battery, be sure battery cables are disconnected.

^ Keep all sparks, lighted matches, and open flames away from the top of the battery. If hydrogen gas escaping from the cap vents is ignited, it will ignite gas trapped in the cells and cause the battery to explode.
