First Claim
1. A battery pack, comprising:
- a first cell block which comprises one or more battery cells, and supplies electrical power by discharging after being charged to the body of an electrical instrument which consumes electrical power;
a second cell block which comprises one or more battery cells, and supplies electrical power to the body of the electrical instrument by discharging after being charged, and becomes selectively active with the first cell block; and
a controller which recognizes the number of charge/discharge cycles of the first cell block and the number of charge/discharge cycles of the second cell block, and selects between the first cell block and the second cell block based on the number of charge/discharge cycles of the first cell block and the number of charge/discharge cycles of the second cell block.

Abstract
In an electrical instrument to which a plurality of battery blocks and/or a plurality of batteries are detachably connectable, to prevent a phenomenon that only specific battery and battery block are deteriorated. A hybrid battery connectable to a body of an electrical instrument consuming electrical power includes: a cell block which includes one or more battery cells, and supplies electrical power to the body of the electrical instrument by discharging after being charged; and a cell block which includes one or more battery cells, supplies electrical power to the body of the electrical instrument by discharging after being charged, and becomes active selectively with the former cell block. In the hybrid battery, a CPU selects a cell block becoming active based on the number of charge/discharge cycles of the former cell block and the number of charge/discharge cycles of the latter cell block.
