Questions about this item
How long will the 4400 mAh capacity actually run a Dell Precision M4400?
The 49 Wh rating translates to roughly three to five hours of mixed office work on a Dell Precision M4400, depending on screen brightness and CPU load.
Does the 11.1 V output match the original Dell 312-7415 battery specification?
Yes, the 11.1 V rating is identical to the OEM 312-7415 and 451-10583 packs, so the laptop's charging circuit recognises it without modification.
Will the six-cell pack fit the battery bay of a Latitude E6400 XFR without a spacer?
The pack uses the standard six-cell form factor for the Latitude E6400 XFR and Precision M2400, so it slides into the bay and locks with the original latch.
