Questions about this item

Will the 9-cell 87 Whr pack fit my Latitude E6400 without a chassis bulge?

The battery matches the original 9-cell form factor for the E6400, E6410, E6500 and E6510 so it seats flush in the standard battery bay.

What is the correct way to seat the battery so the latch engages on a Precision M4400?

Slide the pack in until the release lever clicks audibly; the common mistake is stopping at the first detent instead of pushing through to the second click.

Which Dell part numbers confirm this 7800 mAh unit will replace my original KY265?

The replacement cross-references KY265, KY266, KY268, KY477, PT434, 4M529, 312-0748, 312-0749, FU268, FU272, FU274 and W1193.
