If the voltage is less than 12.4 volts (for a 12 volt battery) or 24.8 volts (for a 24 volt battery), which is typically 75% of charge, the battery may be too heavily sulfated to be fully recoverable. You can determine this two ways. Hook the power cord up to a nearby AC outlet. Working with electricity can be deadly if you are not careful. The procedure for testing a battery charger is similar regardless of the type of battery you’re working with.

This means that as the excess electricity passes through the electrolyte solution, it causes the hydrogen and oxygen molecules within the battery acid to break down, evaporate, the battery to heat up, and sulfation to occur on the lead plates inside the battery. Modern smart chargers (float included) have a minimum voltage that the battery must possess in order for the battery to engage the charging process. This is my first Harley, and I've only ever had imports with my battery's all lasting 4-5 years with no problems.
