Abstract: A battery charging apparatus anticipates usage and thus provides a charged battery available for use. In addition the charging regimen employed substantially eliminates memory effects in NICAD batteries. The battery charging apparatus comprises a power supply for generating a controllable battery charging current which is responsive to battery status. A plurality of calendars, stored in PROM, are user selectable to form a custom calendar. User specific event dates may be added to produce a composite calendar. A microprocessor maintains a real time clock calendar and executes a calendar algorithm. Upon the occurrence of a composite calendar event date, the microprocessor generates a control signal for initiating the battery charging current. The microprocessor also produces a status message display. Message data is stored in PROM and is used to generate a video signal for monitor display. The video signal is also coupled to an RF modulator for TV receiver display.
