87 Whr 9-cell replacement battery

This 87 Whr lithium-ion pack replaces original Dell Latitude batteries for the E6400, E6410, E6500 and E6510 models as well as Precision M2400 and M4400 workstations. It is built for professionals who need a fresh power source for aging but serviceable business laptops.

The unit matches part numbers KY265, PT434, 4M529, KY477, 4N369, 312-0748 and 312-0749 among others. The jump is worth it when the original cell no longer holds a useful charge or when the laptop shuts down unexpectedly under load.

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.
