If you have a device which uses AA
or even AAA
cells, you can purchase Nickel Metal Hydride
) rechargable batteries. They were one of the first kinds of rechargable cell to be hailed as having "no memory effect
" (although in reality, this means "less vulnerable to memory effect
"). While not as spiffy
as Lithium Ion
cells, they do hold considerably more charge than Nickel Cadmium
) rechargables. They can be charged in most existing NiCad
chargers, only the charge times will differ (longer).
PS. Follow the NiMh link for information on where you can buy them.
