HQRP Battery for SDAMX7-RBK-G10 Sandisk Sansa MP3 Player Replacement plus HQRP Universal Screen Protector
I was ecstatic when I found out that I can change the battery for my MP3 player so I ordered 2 of these batteries.  Now my MP3 player is working but I have to keep it on the charger at all times because the battery does not take a charge.
