Replacement battery for ThinkPad T480s

This 57Wh lithium-polymer battery operates at 11.58V and delivers 4920mAh of capacity. It replaces part numbers 01AV478, 01AV479, 01AV480, L17L3P71, L17M3P71, L17M3P72, SB10K97620, SB10K97621 and SB10K97622. The unit is new and designed as a plug-and-play replacement for the Lenovo ThinkPad T480s series.

Who this suits and who it does not

It suits owners of a ThinkPad T480s whose original battery matches one of the listed part numbers. It does not fit the ThinkPad T480, and buyers who cannot open the back case to verify the original battery model number should not order. Builders needing a battery for any other laptop series must look elsewhere.

Bundled items and setup notes

The package includes one 01AV478 battery and no additional cables, tools or software. The supplier advises discharging the new battery to 5% then charging to 95% for three to four cycles before regular use. A one-year warranty and 30-day money-back guarantee are offered by the supplier.

Questions about this item

Will the 01AV478 battery work in my Lenovo ThinkPad T480s without any additional parts?

Yes, it is a plug-and-play replacement for the original 01AV478, L17L3P71, SB10K97620 and L17M3P71 batteries used in the ThinkPad T480s series.

Can I keep my existing Lenovo ThinkPad T480 charger when I install this 11.58V 57Wh battery?

The battery is designed for the ThinkPad T480s series, not the T480, so it will only work correctly with the charger that originally shipped with a T480s.

How do I verify the 01AV478 battery is functioning correctly after the first few charge cycles?

Discharge it to about 5 %, charge to 95 %, and repeat this cycle three to four times; the battery should then hold a stable charge near its rated 57Wh capacity.
