Replacement Battery for Sansa Fuze

This 550 mAh 3.7 V lithium-ion cell replaces the original battery in SanDisk Sansa Fuze 2 GB, 4 GB and 8 GB players. It matches part numbers 8JJH8F15 and CS-MPSF350SL and is supplied as a single new unit.

Soldering Required for Installation

The pack ships as a bare cell without leads or connector, so fitting it demands soldering directly to the player’s mainboard. No tools, adhesive or wiring harness are included in the package.

2.04 Wh Capacity Restores Original Runtime

At 550 mAh the cell delivers the same 2.04 Wh energy rating as the factory battery, giving comparable playback time per charge. It will not extend runtime beyond the stock specification and is unsuitable for players other than the three Fuze capacities listed.
