Replacement battery for Acer Chromebook

This new GreenTech battery replaces OEM part numbers AC14B7K, AC14B18J, KT.0040G.004, KT.0030G.004, AC14B3K, AC14B8K and NP.ADT0A.025. It fits a wide range of Acer Chromebook, TravelMate, Aspire V, E, ES and R series laptops listed in the compatibility data. The four-cell lithium-ion pack is supplied in black and carries CE, FCC and RoHS safety certifications.

Voltage and capacity match

The decisive specification is the 15.28V output combined with a 3318mAh rating that yields 50.7Wh. A replacement must match this voltage exactly; a different voltage will prevent the laptop from charging or powering on correctly. Capacity determines runtime, so the 50.7Wh figure confirms the pack meets the original energy specification.

Typical workloads and limits

A 50.7Wh four-cell pack comfortably powers light productivity, web browsing and video playback for several hours on supported Acer models. It will not sustain heavy multi-core workloads, discrete graphics demands or extended unplugged sessions as long as higher-capacity six-cell or nine-cell alternatives. Buyers needing all-day runtime without charging should consider that this capacity is fixed at the original specification.

Questions about this item

How long will the 50.7Wh capacity actually run my Chromebook CB3-111?

The 50.7Wh rating means the battery stores that much energy; real runtime depends on screen brightness, workload and wireless use, but it matches the original capacity for comparable life.

Does the 15.28V voltage match the original AC14B7K spec exactly?

Yes, 15.28V is the specified voltage for the AC14B7K and all listed replacement part numbers, so it aligns with the laptop's charging circuit.

Will this 4-cell pack fit inside my Aspire V3-371 without modification?

The pack is built to the same form factor as the OEM AC14B7K and is listed as a direct fit for the V3-371 and the other compatible models.
