How do i charge a battery on a Honda rebel motorcycle?

As with any battery, you need a battery charger. They are not too expensive, just make sure that it not only charges at 10 amps, but also at 2 amps. Remove the neg. and pos. cable from the battery, and put the red wire to the positive terminal, and the black wire to the neg. terminal at a charge rate of 2 amps. The charger will tell you when the cycle is complete. May take a day or 2 if the battery is dead. Also make sure the water level is at the top line in the battery. Use only distilled water to top up.
