ganesh040 , does your player currently use the external batteries like the Nokia ones? Or does it use an internal battery pack?

ganesh040 , do you frequently use the speaker? If you use the earphones instead, how long does the battery last?

Internal battery packs are a little trickier as higher capacities are difficult to find. Also, you'll need to check for the space allowed by the player to contain the new battery pack.

Headset usally last 45 - 60 minutes and loudspeaker 4-5 mins only...

the baterry is really flat 1 might be .3-4cm thick and 5-5.5 cm long
