Abstract
A method for charging a rechargeable battery pack includes providing a charger having first and second charging processes, and manually selecting one of the first and second charging processes. The charging method may include a step for indicating status or end of the selected one charging process. The first charging process may include the steps of providing a fast charging current, indicating end of the fast charging current and providing an equalization current. The second charging process may include the steps of providing a fast charging current, subsequently providing an equalization current and indicating end of equalization current. The second charging process may also include a temperature checking step. Further disclosed is a battery charging apparatus including a charger for charging a battery and having first and second charging processes, and a switch connected to the charger for manually selecting one of the first and second charging processes. The charger may include a microprocessor. Further, the apparatus may include a display output and/or sound output connected to the charger. The display output and/or sound output may indicate status or end of the selected one charging process. The display output may comprise a light bulb, a light emitting diode and/or a liquid crystal display. The sound output may comprise a speaker and/or a piezo-electric device.
