Questions about this item

How much heat does the 9-cell 85Wh battery produce during all-day use?

Li-ion cells run cool under normal load; the built-in protection circuit prevents overheating during extended sessions.

Which Dell Studio part numbers must match for this 11.1V pack to fit?

Compatible part numbers are N856P, U164P, M905P, U150P and 312-0196 — verify one of these on your original battery.

Will the 7800mAh capacity work with the original charger on a Dell Studio 1747?

Yes, the 11.1V output matches the factory specification so the existing AC adapter charges it normally.
