  • What should the voltage be on a fully charged battery?

  • When a battery charger has been disconnected from the battery for one to two hours, a fully charged Conventional battery should read 12.6 volts (12.8 volts with Sulphate Stop) or higher. AGM batteries may have slightly higher voltage readings after a full charge.

  • How many volts should a 12 volt battery have?

  • 12-volt batteries supply useful energy only through a limited range 鈥?from over 14 volts (when fully charged and unrested) down to 10.5 volts in use/under load (when lights dim, your motorcycle is hard to start). No 12-volt battery will remain at over 14 volts for more than seconds unless it鈥檚 being charged.

  • How many amps does it take to start a motorcycle?
