ABSTRACT:
A battery pack that comprises a removable supplemental feature cartridge (160). These features can be answering machines, electronic appointment calendars, clock radios, digital recorders, garage door openers, timers, silent alarm vibrators or other items that would be beneficial to keep close at hand. These tag-along cartridges are standardized in size and can be used on battery packs that fit many different cellular telephones and other portable personal communication devices. The cartridges can receive electrical power from or deliver power to the battery pack. Since the cartridges need not contain their own separate battery, the cartridges are sufficiently small and light weight so that several cartridges can be carried in a shirt pocket or purse and be quickly inserted into the battery pack. Cartridges can be quickly switched from a battery pack that is about to be placed on a charger to a fresh battery pack that has just been mounted on a cellular phone.
