Replacement battery for Dell Studio 17 series

This Cameron & Co lithium-ion battery replaces the original Dell pack in Studio 1745, 1747, 1749 and P02E models. It matches OEM part numbers 312-0186, 312-0196, M905P, N855P, N856P, U150P, U164P and Y067P6. The unit ships new and ready to install.

Voltage and capacity match

The cell configuration delivers 11.1 V and 4400 mAh (4.4 Ah), identical to the factory specification. This single electrical rating determines whether the pack will power the notebook correctly; no other specification overrides it.

Thermal and power behaviour

Lithium-ion chemistry provides stable voltage under normal loads with minimal self-heating. The pack operates silently and draws only the current the laptop requests, so battery life and thermals remain consistent with the original design.

Questions about this item

How long will the 4.4 Ah rating actually run my laptop?

The 4.4 Ah capacity at 11.1 V stores roughly 49 Wh, which typically yields several hours of mixed use depending on screen brightness, CPU load and battery age.

Does the 11.1 V output match the original Dell battery specification?

Yes, the 11.1 V nominal voltage is identical to the Dell part numbers 312-0186, 312-0196, M905P, N855P and N856P listed for the Studio 1745, 1747, 1749 and P02E models.

Will the 205.26 x 57.39 x 22.93 mm case fit my Studio 1745 battery bay?

Those exact dimensions correspond to the original Dell battery footprint, so the pack slides into the same bay without modification.
