High capacity Nickel Metal Hydride (NiMH) batteries are
used in high-drain battery-operated devices such as digital cameras, handheld
TVs, portable organizers and two-way radios. According to the manufacturer,
Rayovac NiMH batteries can last up to six times longer than standard Duracell
alkaline batteries and can last up to two times longer than any alkaline
battery, including "super-premiums" like Duracell ULTRA and
Rayovac has developed a 1-hour charger ($35) for NiMH AA
and AAA batteries ($12/package of 4 batteries). The device can also be used to
charge 9-volt NiMH batteries as well as NiCd batteries in various sizes.
Because NiMH batteries can be charged up to 1,000 times
(compared with 25 times for rechargeable alkaline batteries) their use can
result in significant cost savings over alkaline batteries.
