Replacement Battery for ThinkPad X1 Yoga and Carbon

This new lithium polymer battery replaces part numbers including SB10F46466 00HW028 01AV441 for ThinkPad X1 Yoga 1st Gen 20FQ 20FR and 2nd Gen 20JD 20JE 20JF 20JG plus X1 Carbon 4th Gen 20FB 20FC. It delivers 15.2V and 52Wh capacity across four cells.

Sustained Runtime and Cell Balance

The 3440mAh rating supports consistent output during extended sessions rather than only brief peaks. Four lithium polymer cells share the load to reduce voltage sag under continuous drain. No additional thermal or cycle-life data is supplied.

Verify Part Number and Physical Match

Confirm the original battery part number matches one of the listed compatibles such as 00HW029 01AV409 01AV410 01AV438 01AV439 01AV440 01AV444 01AV457 01AV458 SB10K97566 SB10K97567 SB10F46467. Check connector shape and cable length against the product images because dimensions and wiring can differ even within the same laptop series.

Questions about this item

How much heat or power draw should I expect from the 15.2 V 52 Wh lithium-polymer pack during all-day use?

The battery stores 52 Wh at 15.2 V and uses lithium-polymer chemistry; heat and power draw depend on the laptop's workload, not the pack itself.

What must I already own to install this SB10F46466 replacement?

You need a ThinkPad X1 Yoga 1st Gen 20FQ/20FR, 2nd Gen 20JD/20JE/20JF/20JG, or X1 Carbon 4th Gen 20FB/20FC, plus a small Phillips screwdriver to open the case.

Will the 4-cell 3440 mAh pack fit and charge correctly in a 20FB series X1 Carbon that currently uses an 00HW028 battery?

Yes — 00HW028 is listed among the compatible part numbers, so the connector and firmware handshake match the original design.
