The very latest 5th Generation of Panasonic Eneloop Pro AA 2500mAh Ni-MH Batteries for professional use are AA size NiMH 1.2V rechargeable batteries.
They are the ideal choice for powering high drain devices such as GPS Units.
Panasonic has developed the Panasonic Eneloop Pro AA batteries to perform in extreme conditions where high power performance in very low-temperature environments is needed even down to -20°C.
Panasonic Eneloop pro batteries are pre-charged and can be used straight from the pack. They are also low self-discharge rechargeable batteries, retaining up to 85% of their capacity even after one year of storage.
Unlike ordinary alkaline batteries which can only be used once and are wasteful to the environment, the Panasonic Eneloop pro batteries can be recharged up to 500 times.
