Panasonic Eneloop 4.8V 2000mAh AA Ni-MH Receiver Pack Flat
Panasonic Eneloop batteries have superb charge retention with 90% after 6 months, and 85% even after a year, so no need for regular charging to aviod permanent capacity loss required by many Ni-MH cells.
Eneloop cells retain a much higher voltage under load, the voltage does not collapse when high currents are pulled, which is an unwelcome characteristic of normal AA Ni-Mh cells.
Over double the cycle life of most Ni-Mh cells, over 2100 cycles are possible! Specification
Dimensions: 50 x 60 x 10mm
