Replacement battery for Galaxy Prevail 2

The Cameron & Co DS-CS-SMM840XL is a new lithium-ion cell rated at 3.7 V and 1.9 Ah. It matches the Samsung EB494865VO specification and fits Galaxy Prevail 2, Galaxy Prevail II, Galaxy Ring and SPH-M840 handsets. The black pack measures 64.91 x 47.93 x 4.87 mm and delivers 7.03 Wh.

Owners of the listed Samsung models needing

This unit suits anyone whose original EB494865VO cell no longer holds charge and who wants a 100 % OEM-compatible replacement without modification. Buyers with other phone models or different battery part numbers should look elsewhere because the connector and dimensions are specific to the SPH-M840 series.

1900 mAh capacity at 3.7 V

The single figure that decides fit is the 1900 mAh rating at 3.7 V, which equals 7.03 Wh. If your device requires that exact energy capacity and voltage the battery will work; if the original spec differs the cell will not be suitable.

Questions about this item

Does the 3.7 V 1900 mAh cell run warm after a full day of calls?

Lithium-ion chemistry at 3.7 V and 1900 mAh typically stays cool during normal phone use; no active cooling is needed.

My Galaxy Prevail 2 still has the original back cover — will the 64.91 x 47.93 x 4.87 mm pack fit without modification?

Yes, the 64.91 x 47.93 x 4.87 mm dimensions match the Samsung EB494865VO form factor, so the existing cover closes normally.

Can I keep using my existing micro-USB charger and car adapter with this 7.03 Wh replacement?

The 7.03 Wh capacity works with the phone's original charging circuit, so your current micro-USB charger and car adapter remain compatible.
