Compatible Dell Chromebook models

This 11.4 V lithium-polymer battery replaces part numbers 51KD7, FY8XM and Y07HK. It fits Dell Chromebook 11 models 3100, 3180, 3181, 3189 and 5190 as well as the P26T chassis. The 42 Wh cell restores factory run-time for students and mobile workers who rely on these specific devices.

Installation and system fit

The pack slots into the existing battery bay without adapters or cable changes. It reuses the original connector and mounting points, so no extra hardware is required. Swapping the old unit frees the notebook from permanent wall power and restores untethered use in classrooms or on the move.

Thermals, noise and power draw

Li-polymer chemistry runs cool during typical charge and discharge cycles. The battery adds no moving parts, so acoustic output stays at zero. Normal operation draws only the current the Chromebook requests, keeping system thermals unchanged from the original pack.

Questions about this item

How many watt-hours does the 42Wh 11.4V battery deliver before the Chromebook 11 3180 shuts down under continuous load?

The pack is rated at 42Wh, so sustained use will draw from that capacity until the system initiates its low-voltage shutdown.

What temperature or fan behaviour should I expect from the Li-polymer 3500mAh cell when the Dell Chromebook 11 3189 runs all day?

Li-polymer cells run cooler than cylindrical types; the battery itself has no fan, so heat depends on the laptop's own thermal design.

Which Dell Chromebook 11 part numbers must my device already carry for the 51KD7 replacement to fit and connect?

The battery replaces part numbers 51KD7, FY8XM and Y07HK and fits models 3180, 3189, 5190, 3181 and P26T.
