Cameron & Co DS-CS-MUX640SL cell phone battery 4.75 Ah

Replacement Battery for Xiaomi Mi Max

The Cameron & Co DS-CS-MUX640SL is a lithium-polymer cell rated at 4.75 Ah and 3.85 V, delivering 18.29 Wh. It fits the Xiaomi 2016001, 2016002 and 2016007 models, including the Hydrogen, Max and Mi Max Dual SIM TD-LTE variants. The pack replaces the original BM49 part number and ships in black.

Practical Limits of a Single-Cell Pack

A single lithium-polymer pouch tops out at the rated capacity; no higher milliampere-hour option exists in this form factor. Voltage sags under heavy load, so sustained camera flashes or GPS navigation will reduce usable runtime below the nominal 4750 mAh figure. The 3.46 mm thickness leaves no room for a larger cell without modifying the chassis.

Upgrading From a Degraded Original

This unit restores factory runtime when the original battery no longer holds a full day's charge. It is not for users who need more capacity than the OEM design allows, nor for phones outside the listed model numbers. The jump is worth it when shutdowns appear at 20 % indicated charge or when screen-on time has dropped by half.
