Abstract
A method and system for battery charging. In some aspects, an electrical combination comprises a first battery having a Lithium-based chemistry, the first battery having a first nominal voltage in a nominal voltage range, a second battery having a Lithium-based chemistry, the second battery having a second nominal voltage, the second nominal voltage being different than the first nominal voltage and being outside of the nominal voltage range, and a battery charger operable to charge the first battery and the second battery. In some aspects, a method of charging a battery, a first battery having a Lithium-based chemistry, the first battery having a first nominal voltage in a first nominal voltage range, a second battery having a Lithium-based chemistry, the second battery having a second nominal voltage in a second nominal voltage range, the second nominal voltage being different than the first nominal voltage, the second nominal voltage range being different than the first nominal voltage range, a battery charger being operable to charge the first battery and the second battery, includes the acts of electrically connecting the battery charger and the first battery, charging the fir…
