Compatible replacement for Latitude 9440 2-in-1

This new GreenTechLLC battery replaces the original Dell GT6TK, MWK05 and K2CPY part numbers. It fits the Latitude 9440 2-in-1 and Latitude 9450 2-in-1 models. The three-cell lithium-ion pack restores mobile power for users whose original battery no longer holds a useful charge.

60 Wh capacity and 5065 mAh at 11.55 V

The 60 Wh rating supplies a full day of typical office work on a single charge. Capacity drops noticeably after several hundred cycles, so heavy travellers should expect shorter runtimes over time. The 11.55 V output matches the laptop's power rail exactly.

Direct-fit lithium-ion pack

The battery slides into the existing bay without adapters or cable changes. It is certified to CE, FCC and RoHS standards for electrical safety and substance restrictions. Buyers needing a higher-watt-hour pack or a different form factor will not be served by this unit.
