Iriver B30 low battery and will not charge - iRiver B30 (8 GB) Digital Media Player

The battery maybe worn out.
If the Media player battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

Sounds like the battery is dead. Rechargeables only last so long. I'd copy all the content off it, before the battery dies totally, which could make it not work even connected to your computer. Looks like you can get a replacement battery: Iriver h340 Google Search

Open the player and test for battery's voltage. In case of a low voltage measurement,you should replace the battery.I don't want to be cruel with you but, maybe that the player power circuit was damaged as well,and in this case it should be repaired by a certified technician (I realy hope for you that this is not the situation). Good luck !!!
