Dell K5NN2 6-Cell Battery

The Dell K5NN2 is a 6-cell lithium-ion laptop battery rated at 65 watt-hours and 5800 milliampere-hours. It operates at 11.1 volts and replaces Dell part number 0K5NN2. This new component restores original runtime to compatible Dell notebooks.

Suitability and Limits

Fits owners of Dell laptops that accept the 0K5NN2 part number and need a direct voltage and capacity match. Unsuitable for machines requiring a different cell count, voltage or proprietary connector. Buyers who want more storage or a higher-watt-hour pack should look elsewhere.

Questions about this item

What Dell laptop models accept the K5NN2 6-cell battery with 11.1 V output?

The K5NN2 replaces Dell part number 0K5NN2; check your laptop's service manual or original battery label for that exact part number before ordering.

Will this 65 Wh battery fit in the same bay as my original 4-cell pack?

The 6-cell design is physically larger than a 4-cell pack; verify your chassis has the extended battery bay or a compatible bottom door before installing.

How can I confirm the new battery is delivering the rated 5800 mAh after installation?

Run a full charge-discharge cycle in the BIOS battery calibration utility or Dell Power Manager; the reported full-charge capacity should approach 5800 mAh when the cycle completes.
