i paid $10 for 4 duracell nimh, then i bought 4 more...they are great. i have a $30 1 hour charger, it would kill any alkaline but dayum!
one hour, i get about 2-3 weeks on my wireless mouse, a month on my keyboard, a few hours in my cd player (those ones are over 600 charges in) and flashlights, well, dunno. They havnt died yet, but how often do i use a flashlight?
Great things, paid for tehmselves in less than a month for me. (and i diddnt have a job at that point, it was allot of cash)
