rechargeable batteries

my sons sansa i going through batteries like water so i bought rechargeables now its not working at all is there something wrong

if im not mistaken the good replacable batters are ni-mh, or alkaline. I wouldnt recommend though, I have heard of people complain of the degredation of the units life. Just from what I read, im sure other users have different experience.

i’d say rechargable alkaline instead…
