Replacement battery for ThinkPad L-series

This 11.1 V Li-ion pack replaces the original battery in Lenovo ThinkPad L470, L480, L580 and L590 laptops. It uses cells made in Japan and a matching PCB to deliver the rated 4050 mAh capacity. The physical dimensions match the factory unit so installation requires no modification. Condition is new and the supplier includes a one-year warranty.

Suitable for owners of listed models needing

Users whose ThinkPad is not one of the four models above should look elsewhere because the connector and case profile will not match. Buyers who want a higher-capacity extended pack will not find it here; this unit matches the standard 45 Wh design. Anyone unwilling to perform the initial charge-cycles described by the maker should consider professional fitting.

11.1 V 4050 mAh 45 Wh rating

The voltage and capacity figures determine whether the battery will report correctly to the system power manager and provide the expected runtime. A pack with a different voltage or substantially different watt-hour value will cause calibration errors or reduced operating time. Verify the original battery shows 11.1 V and 4050 mAh before ordering.

Questions about this item

How long will the 45 Wh capacity last before the voltage drops under a full-day workload?

The 45 Wh rating gives the total energy available; actual runtime depends on the laptop's power draw and the 11.1 V output under load.

Does the Li-ion cell generate noticeable heat or fan noise during continuous charging?

The battery itself has no moving parts, so it adds no fan noise; heat varies with the laptop's charging circuit and ambient temperature.

Which original battery model numbers must match for this replacement to fit?

It replaces Lenovo part numbers 01AV463 and L17M3P53 and fits ThinkPad L470, L480, L580 and L590 models.
