Owners of the listed devices who need a like-for-like power cell will find this unit matches the original voltage and capacity. Buyers whose handset uses a different form factor or voltage should look elsewhere. No other device compatibility is claimed.
3.8V 2900mAh lithium-ion cell
The single specification that decides fit is the 3.8V 2900mAh rating combined with the 89.66 x 59.90 x 4.60 mm footprint. If the original battery shares these exact values, this part will seat and function correctly. Any deviation in voltage, capacity or dimensions means the part is not suitable.

Questions about this item
How do I install the BLUE050 battery and what step is often missed?
Power off the device, remove the back cover, disconnect the old pack, connect the new 3.8V 2900mAh unit matching the connector orientation, then reassemble. The step often missed is verifying the connector clicks fully before closing the case.
What maintenance or replacement will the BLUE050 battery need later?
The 2900mAh lithium-ion cell will gradually lose capacity over charge cycles. Plan to replace it when run-time drops below your needs; no scheduled maintenance is required beyond avoiding deep discharge and extreme temperatures.
What limit appears first during sustained use of the BLUE050 battery?
The 3.8V nominal voltage will sag under continuous high-current draw, triggering the device's low-voltage cutoff. This voltage floor is the first limit reached before thermal throttling or capacity depletion becomes critical.
