97 WHr 9-Cell Battery for Dell Latitude E Series

This 97 WHr lithium-ion battery uses a proprietary 9-cell design rated at 4400 mAh and 10.8 V DC. It serves as a direct replacement for the original primary battery in compatible Dell Latitude E series notebooks. The rechargeable pack restores full mobile operation when the original cell no longer holds a useful charge.

Replaces OEM part numbers including 04NW9

The unit matches a long list of Dell OEM part numbers such as 312-1164, 312-1242, 312-1323 and 312-1324 among others. Swapping to this new pack is worth it when runtime has dropped below usable levels or the original battery reports a permanent failure. It also covers replacements for the 4YRJH and 8858X service codes.

Fits Latitude E5420 E6420 E6430 and related models

Compatibility extends across Latitude E5420, E5430, E5520, E5530, E6420, E6430, E6440, E6520 and E6530 chassis including rugged ATG and XFR variants. The proprietary form factor slots into the existing battery bay without adapter cables or chassis modification. It frees the user from tethered AC-only operation and restores hot-swap capability on models that support it.

Questions about this item

Will the 9-cell battery fit the Latitude E6420 without a chassis bulge?

The 97 WHr 9-cell pack uses Dell's proprietary form factor and matches the OEM dimensions for the E6420, so it seats flush with the base.

Which step do users miss when installing the 2P2MJ in a Latitude E5530?

After sliding the pack into the bay, the latch must click audibly; a silent seat means the contacts are not fully engaged.

What replacement does the 4400 mAh lithium-ion pack need after extended use?

The battery itself is the only replaceable component; once its runtime falls below usable levels the whole 9-cell unit is swapped.
