Replacement charging-case battery

This Cameron Sino cell replaces the original battery inside the Sony WF-1000XM3 charging case. It is a lithium-ion unit rated at 800mAh and 2.96Wh with a nominal voltage of 3.7V. The pack measures 49.50 x 17.10 x 14.50mm and weighs 21.4g. A fully decoded chip ensures it works like the factory part.

For owners needing a fresh case cell.

This battery suits anyone whose WF-1000XM3 case no longer holds a charge. It is not for the individual earbuds themselves, which use separate cells. Buyers who cannot open the case or solder a connector should look at professional repair instead. Compatibility must be verified against part number 1588-0911 before purchase.

800mAh capacity decides fit

The 800mAh / 2.96Wh capacity is the single figure that determines whether this cell matches the original specification. If the original case battery shows a different milliampere-hour or watt-hour rating, this unit will not be a correct replacement. Always compare the printed values on the old battery with 800mAh and 2.96Wh.

Questions about this item

Does this 800mAh 3.7V battery fit my Sony WF-1000XM3 charging case with part number 1588-0911?

Yes, it is a direct replacement for the Sony 1588-0911 cell used in the WF-1000XM3 charging case and the WF-SP900 model.

Will the decoded chip work with the original case electronics without firmware issues?

The fully decoded chip communicates with the case circuitry exactly like the original battery, so charging and level reporting function normally.

How can I verify the new 2.96Wh cell is working correctly after installation?

Place the earbuds in the case and confirm the LED indicators show charging status; a full charge cycle should then power the buds for their rated playback time.
