Cameron & Co DS-CS-BQU100SL cell phone battery 2950mAh 3.85V

Direct replacement battery

The Cameron & Co DS-CS-BQU100SL is a 3.85V 2950mAh lithium-polymer cell built for the BQ Aquaris U, U Lite and U Plus smartphones. It matches the original 3080 part number and delivers 11.36Wh of capacity in a slim 82.00 x 61.20 x 3.50 mm black pack. The 100% OEM-compatible design fits the existing battery compartment without modification. Owners of those three handset models can restore factory runtime with a single swap.

Thermals and daily draw

Lithium-polymer chemistry keeps internal resistance low, so the cell stays cool during typical messaging, browsing and call loads. Normal discharge follows the 3.85V nominal voltage without noticeable voltage sag, and the thin 3.50 mm profile leaves no air gap that could trap heat. There is no active cooling required; the phone’s own chassis dissipates the modest warmth generated in everyday use. Standby leakage is minimal, preserving charge overnight.

Upgrade context

This unit replaces a worn or swollen original battery in the Aquaris U series, restoring full-day autonomy when the old cell no longer holds 2950mAh. The jump is worth it when runtime has fallen below a usable threshold or the back cover bulges from gas buildup. It is not for users seeking higher capacity than the factory specification, nor for devices outside the U, U Lite and U Plus lineup. No other form factor or voltage is supported.
