Replacement battery for ThinkPad S2 13

This new lithium-ion unit delivers 42Wh at 11.4V and fits the ThinkPad S2 13 Chromebook and listed ThinkPad 13 models. It replaces part numbers 01AV400, 01AV401, 01AV402, 01AV435, 01AV436 and 01AV437. Buyers needing a different voltage or capacity cannot use this pack.

Package contents and compatibility

The box contains one battery only; no tools, screws or software are supplied. The supplier notes that the six part numbers are interchangeable despite voltage differences and will ship whichever is in stock. Users who require a specific part number must verify before ordering.

Installation notes

Fitting requires opening the laptop chassis and disconnecting the original pack, so basic disassembly skill is needed. The part-number list covers many 2018-era ThinkPad S2 and ThinkPad 13 variants, but models outside that range are not supported.

Questions about this item

How many charge cycles before the 42Wh lithium-ion cell needs replacing?

The 11.4V 42Wh lithium-ion pack is rated for typical lithium-ion cycle life; expect replacement after several hundred full cycles when runtime drops below your needs.

What limits runtime first during a full-day workload on the ThinkPad S2 13 Chromebook?

The 42Wh capacity sets the hard ceiling; sustained loads will drain the pack in proportion to the system's power draw until the 11.4V output falls below the laptop's minimum.

Does the battery get hot or noisy when the ThinkPad 13 runs all day on the 11.4V pack?

The lithium-ion cell has no moving parts so it stays silent; warmth is normal under load but the pack is designed to operate within the laptop's thermal envelope.
