Replacement Battery for BLU E050 Series

This Cameron & Co DS-CS-BLX250SL is a lithium-ion cell built for the BLU E050, E050U and Energy X2 smartphones. It restores original runtime when the factory pack no longer holds a charge. Installers should verify the exact model number before fitting.

Capacity Decides Compatibility

The cell delivers 3.8 V and 2900 mAh for 11.02 Wh of energy. Only devices that specify this voltage and capacity will charge and report remaining power correctly. A different rating will cause inaccurate readings or prevent the phone from booting.

Thermals and Power in Daily Use

Normal operation keeps the pack near ambient temperature with no audible noise. Current draw follows the phone's own power management, peaking during calls or data sessions and dropping to microamps in standby. No active cooling is required.

Questions about this item

How long will the 2900 mAh capacity last in daily use?

The 2900 mAh rating means the cell can supply 2.9 amps for one hour; actual screen-on time depends on the phone's power draw and your usage pattern.

What does the 3.8 V nominal voltage mean for charging?

The 3.8 V nominal voltage is the standard for single-cell Li-ion packs; the phone's charging circuit manages the voltage range, so you simply install the battery and charge normally.

Will the 89.66 x 59.90 x 4.60 mm size fit my BLU Energy X2?

Yes, those dimensions match the original C906052400L battery specified for the BLU E050, E050U and Energy X2 models.
