Replacement battery for Dell Chromebook 11 3180

This new 11.4V lithium-ion pack replaces the original 51KD7 cell in Dell Chromebook 11 3180, 3181, 3189 and 5190 models. It is built for owners who need a direct swap to restore mobile runtime without soldering or adapter changes.

Voltage and cell count match the factory spec

The battery delivers 11.4V from three lithium-ion cells, matching the voltage and topology Dell designed for these Chromebooks. A different voltage or cell arrangement would prevent the system from recognising or charging the pack.

42Wh capacity covers a typical school or work day

At 42Wh the pack provides several hours of browsing and document editing on a single charge. Heavy video playback or sustained high brightness will drain it faster, and the fixed three-cell design cannot be expanded for longer runtime.

Questions about this item

How long will the 42Wh capacity run my Chromebook 11 3180 on a single charge?

The 42Wh rating represents the total energy the 3-cell pack can store; actual runtime varies with screen brightness, workload and wireless use.

Will the 3-cell pack fit inside the existing battery bay without modification?

Yes, the pack is built to the same physical dimensions as the OEM 51KD7 unit and seats directly in the Chromebook 11 3180 battery compartment.
