mobile battery in cheap mp3 player
help me i hv a cheap mp3 player which is not charging now...and i cant find its battery replacement in market... so i am thinking of attaching a mobile's battery(nokia bl-5b which i hv 3 in spare) to the mp3 player as power source ... my question is will it work since both battery gives output of 3.7v ???
and will it give longer playing time my... mp3 player was previously giving me roughly 1 hour of play time with that tiny 3.7v battery... ???
