Replacement battery for ThinkPad X1 models
The GreenTechLLC L24M3P70 is a new 11.7 V 57 Wh lithium-ion pack built to replace Lenovo part numbers 5B11M90097 through 5B11M90100. It fits ThinkPad X1 2-in-1 Gen 10 and X1 Carbon 13th Gen machines across the listed sub-models. Three cells deliver 4875 mAh in a black housing measuring 11.25 by 3.8 by .2 inches and weighing .7 lb.
Suits owners of compatible X1 2-in-1
Buyers with other ThinkPad lines or earlier X1 generations should look elsewhere because the connector and chassis keying differ. Anyone needing a higher-capacity pack or a different voltage will not be served by this 57 Wh design.
Fits the internal battery bay without extra cabling
The pack slides into the existing compartment and connects to the motherboard header, freeing the external power port for peripherals. No additional adapters or firmware tools are required beyond the standard Lenovo battery calibration routine.

Questions about this item
Do I need the original Lenovo ThinkPad X1 2-in-1 Gen 10 or X1 Carbon 13th Gen laptop for this 11.7 V 57 Wh battery to work?
Yes, this GreenTech L24M3P70 battery is designed specifically for Lenovo ThinkPad X1 2-in-1 Gen 10 (21NU, 21NV, 21Q0, 21Q1) and X1 Carbon 13th Gen (21NS, 21NT, 21NX, 21NY) models; it replaces OEM part numbers 5B11M90097 through 5B11M90100, L24B3P70, L24D3P71, L24M3P70 and SB11M89898 through SB11M89901.
Will the 3-cell 11.7 V pack fit alongside the existing internal components in my ThinkPad X1 Carbon 13th Gen 21NS?
The battery measures 11.25 x 3.8 x 0.2 inches and weighs 0.7 lb, matching the form factor of the original 3-cell lithium-ion unit so it occupies the same internal bay without interfering with other hardware.
How can I verify the 4875 mAh 11.7 V battery is operating correctly after installation?
Power on the laptop and check the OS battery report or Lenovo Vantage; it should show a design capacity of 57 Wh, a voltage near 11.7 V and a full-charge capacity close to 4875 mAh with stable discharge and no error codes.
