Replacement Li-Polymer cell

This Cameron & Co DS-CS-MUM500SL is a 2.9 Ah, 3.8 V lithium-polymer battery built as a direct replacement for the Xiaomi Mi 5 family. It matches the original BM22 part number and delivers 11.02 Wh in a 69.40 x 57.85 x 4.10 mm black cell. The unit is new and rated 100 % OEM compatible.

Xiaomi Mi 5 owners needing a fresh cell

Owners of the Xiaomi Gemini, Mi 5, Mi 5 Gold Edition, Mi 5 Gold Edition Dual SIM, Mi 5 Pro, Mi 5 Pro Ceramic Edition or Mi 5 Pro Ceramic Edition Dual SIM models can use this pack to restore original runtime. Buyers whose phone uses a different battery code or form factor should look at another listing.

2.9 Ah capacity at 3.8 V

The single figure that decides fitment is the 2.9 Ah / 3.8 V rating, which equals 11.02 Wh and corresponds to the BM22 reference. If the original battery shows different voltage or capacity values this cell will not be the correct part.

Questions about this item

Does the 3.8 V Li-Polymer cell run hot during continuous daily use?

The battery is rated at 2.9 Ah and 11.02 Wh, matching the original BM22 specification, so heat output stays within the phone's designed thermal limits.

What must I already own to install the DS-CS-MUM500SL?

You need a compatible Xiaomi handset — Gemini, Mi5, Mi5 Gold Edition, Mi5 Gold Edition Dual SIM, Mi5 Pro, Mi5 Pro Ceramic Edition or Mi5 Pro Ceramic Edition Dual SIM — and a small Phillips screwdriver to open the back cover.

Will the 69.40 mm × 57.85 mm × 4.10 mm pack fit my original Mi5 Pro Ceramic Edition without forcing the cover?

Yes, the dimensions match the factory BM22 cell exactly, so the original back cover closes flush with no gaps or pressure marks.
