Abstract
A method and apparatus is provided which uses a plurality of batteries that are sequentially used to power an appliance. While one or more batteries are used to power the appliance, one or more spar batteries are charged for subsequent use. The rate of charge of the batteries is comparable to the rate of discharge of the batteries by the appliance or faster. Thus the appliance may be essentially continuously used by the user removing the discharged battery and inserting a charged battery.
Claims35
1) A system comprising:
- a) a battery-powered appliance adapted for removably receiving a battery pack, the appliance adapted to discharge a battery pack received therein at a particular rate of discharge;
- b) a battery charger adapted to recharge at least one battery pack at a particular rate of charge;
- and,
- c) first and second battery packs
- wherein the rate of charge of a battery pack in the battery charger is about the same or greater than the rate of discharge of a battery pack by the appliance.

16) A method comprising:
- a) providing a battery-powered appliance adapted for removably receiving at least one battery, a battery charger adapted to recharge at least one battery at a particular rate of charge, and at least first and second battery packs,
- b) operating the appliance with at least the first battery pack wherein the at least first battery pack is discharged at a rate particular rate of discharge;
- c) charging the second battery pack at the rate of charge wherein the rate of charge is about the same as or faster than the rate of discharge.
30) A system comprising:
- a) a plurality of different appliances, each appliance adapted to discharge a battery pack received therein at a particular rate of discharge;
- b) a plurality of battery packs, wherein each appliance is operable using one or more of the battery packs;
- and,
- c) charging means to simultaneously charge a plurality of battery packs, the charging means having a rate of charging a battery pack
- wherein the rate of charge of a battery pack in the battery charger is about the same or greater than the fastest rate of discharge of a battery pack by an appliance.
