Replacement battery for ThinkPad L480 L580

This 45Wh lithium-ion unit replaces the original battery in Lenovo ThinkPad L480 and L580 series laptops. It arrives new in black and carries a 12-month warranty. The pack includes one battery ready for installation.

Voltage and capacity match 11.1V 45Wh

The decisive specification is the 11.1V 45Wh rating, which must match the original battery label. This unit covers part numbers L17L3P52 L17C3P52 L17M3P53 L17M3P54 and 31CP6/55/90, so any of those codes on the old battery confirms compatibility.

Suits owners of listed ThinkPad models

Buyers with a ThinkPad L480 or L580 from the listed sub-models can use this replacement. Users of other ThinkPad series or different laptop brands should look elsewhere because the connector and form factor will not fit.

Questions about this item

How long will the 45 Wh capacity keep a ThinkPad L480 or L580 running on a single charge?

Runtime depends on the laptop's power draw; a 45 Wh pack typically delivers several hours of mixed office use on these models.

Does the 11.1 V rating match the original battery voltage for the L480 and L580 series?

Yes, 11.1 V is the standard voltage for the factory batteries used in ThinkPad L480 and L580 systems.

Will this battery fit the internal bay of a ThinkPad L480 or L580 without modification?

It is built to the same form factor as the original L17L3P52, L17C3P52, L17M3P53 and L17M3P54 packs, so it seats directly in the existing bay.
