Charging a motorcycle battery is essential to getting winterized bikes back on the road or restoring vintage motorcycles. Motorcycle batteries are a bit more complicated than car batteries in terms of charging, however by following these simple steps your battery should be charged and you back on the road in no time.
Instructions
1. Begin by estimating the current charge in the battery. Unscrew one of the top caps and insert the hydrometer into the well, suck up some electrolyte and see how many balls float. Use the chart associated with the hydrometer to determine the charge level.
2. Add deionized water to the wells if the level is below the minimum fill line. You will need to unscrew each of the caps and fill each well separately. Make sure all of the wells are even.
3. Plug the battery charger into the wall, set on 6-volt charge and hook the wires up to the appropriate terminals (positive and negative). Charge the battery at one-third its rated capacity in amps/hour for four to five hours in order to get to full charge.
