Compatible Replacement Battery

This new GreenTechLLC battery replaces multiple OEM part numbers for the Lenovo 13w 2-in-1 Gen 3 series. It is a direct-fit lithium-ion pack designed for owners of the 83M9 and 83MA models who need a fresh power source. The unit ships ready to install with no extra adapters required.

Voltage and Capacity Match

The pack delivers 15.6V and 54.7Wh from a 4-cell 3510mAh configuration. These three figures must match the original battery exactly or the laptop will not charge or report capacity correctly. Buyers whose machine calls for a different voltage or watt-hour rating cannot use this part.

Drop-In Fit for Listed Models

The battery measures 9.65 by 3.5 by 0.2 inches and weighs 0.7 lb, matching the OEM footprint for the 13w 2-in-1 Gen 3 chassis. It frees the user from tethered outlet use and restores full mobile runtime. Systems outside the 83M9 and 83MA families are not supported.

Questions about this item

What runtime can I expect from the 54.7 Wh rating once this battery is installed in my Lenovo 13w 2-in-1 Gen 3?

The 54.7 Wh capacity matches the original specification, so you should see the same battery life the laptop delivered when it was new, assuming typical mixed workloads and screen brightness.

Does the 15.6 V output connect through the standard internal battery connector used by the 13w 2-in-1 Gen 3 models 83M9 and 83MA?

Yes, this replacement uses the exact connector and pinout Lenovo specifies for those models, so it plugs straight into the motherboard without adapters.

Will the 9.65 x 3.5 x 0.2 inch dimensions and 0.7 lb weight fit the existing battery bay without modification?

Those measurements match the OEM pack, so the battery sits flush in the bay and the original screws and latches secure it normally.
