Replacement battery for ThinkPad Yoga 260 370 X380

This 44Wh lithium-ion pack replaces the original Lenovo battery in ThinkPad Yoga 260 370 X380 and S1 2018 models. It matches part numbers 01AV432 01AV433 01AV434 00HW026 00HW027 and cell codes 4ICP5/53/88 4ICP5/54/88. The 15.2V output and 2.895Ah capacity restore factory runtime for mobile professionals.

Straightforward swap with break-in routine

The pack fits the original bay without modification so installation is a simple removal and replacement. The supplier recommends two or three full charge and discharge cycles at low current to calibrate the fuel gauge. Avoid leaving the AC adapter connected continuously during use and keep the battery away from heat and humidity to prevent premature wear.

44Wh capacity for typical workday loads

At 44Wh the cell delivers enough energy for several hours of office tasks web browsing and video playback on the supported Yoga models. Heavy workloads such as sustained compiles or external GPU use will drain the pack faster and may require a midday recharge. For storage longer than one month charge above 80 percent and repeat monthly to maintain health.

Questions about this item

How can I verify the KingSener 00HW027 is working correctly after installation?

After fitting the battery, charge it fully then run it down to low level. Repeat this full charge and discharge cycle two or three times as recommended to stabilise the cells and confirm the 44Wh capacity is delivered.

What comes with the KingSener 00HW027 and what must I source separately?

The package contains the 15.2V 44Wh Li-ion replacement battery only. No tools, screws, adapters or installation guides are included; you will need a suitable screwdriver and any model-specific brackets yourself.

Which part number should I match — 01AV432, 01AV433 or 01AV434 — for my ThinkPad Yoga 260, 370 or X380?

All three part numbers (01AV432, 01AV433, 01AV434) and their SB10K equivalents are listed as compatible with the 00HW027. Compare the label on your original battery to the photos and choose the one that matches exactly.
