Compatible Dell Latitude 2-in-1 battery

This 60 Wh lithium-ion pack replaces the original K5XWW cell in Latitude 12 5285, 5289, 7389 and 7390 convertible models. It delivers 7.6 V nominal voltage and matches the factory form factor for tool-free installation. Buyers needing power for other Dell series or non-convertible chassis should look elsewhere.

7.6 V lithium-ion chemistry limits

The cell chemistry fixes output at 7.6 V, so runtime scales directly with the 60 Wh rating and the host laptop's power draw. No firmware tuning or external circuitry can raise the voltage ceiling. Systems that expect a different nominal voltage will not recognise the pack.

Black polymer casing with direct-fit connectors

The matte black housing aligns with the Latitude 12 battery bay and uses the original locking tabs for a flush fit. No adapter cables or shims are required. Users who prefer a user-replaceable door or hot-swap capability will not find those features on this internal pack.

Questions about this item

Which capacity should I pick for my Latitude 12 5285 2-in-1?

This battery is supplied as a single 60Wh unit that replaces Dell part numbers K5XWW 725KY N18GG 71TG4 CFX97 X49C1 0X49C1 0CFX97 21CP4/58/-90-2.

What does the 60Wh rating mean for daily runtime on a Latitude 7390?

At 7.6V the pack stores 60Wh, which typically delivers several hours of mixed office work on a Latitude 7390 depending on screen brightness and workload.

What connection standard does the K5XWW use and what does it limit?

It uses the proprietary Dell Latitude 12 2-in-1 battery connector, so it only fits the 5285 5289 7389 7390 7280 series and cannot be used in other Dell models.
