45Wh 11.1V Replacement Battery

This 45Wh lithium-polymer battery operates at 11.1V and contains three cells rated for 500 recharge cycles. It replaces Lenovo part numbers including 01AV445 through 01AV448 and SB10K97606 through SB10K97609. Built-in protection covers overcurrent, overcharge, overdischarge and temperature extremes. The unit is new from the manufacturer.

Fits ThinkPad E-Series 14 and 15 Inch Models

The battery fits ThinkPad E480, E485, E490, E495, E580, E585, E590, E595, E14 Gen 1 and E15 Gen 1 machines, including type numbers 20KQ, 20KN, 20KU, 20N8, 20N9, 20NE, 20KS, 20KV, 20NB, 20NF, 20RA and 20RD. It does not suit users whose laptop model falls outside this E-series range or who need a higher-capacity pack than 45Wh.

11.1V 45Wh Three-Cell Specification

The decisive specification is the 11.1V 45Wh three-cell lithium-polymer design rated for 500 cycles. Match this voltage, capacity and cell count exactly to the original battery label before ordering. A different voltage or capacity will not work in the listed ThinkPad models.

Questions about this item

What physical dimensions or connector does the 3-cell 11.1V battery use to fit the ThinkPad E480?

The pack is a direct replacement for Lenovo part numbers such as 01AV448 and L17C3P51 and matches the original 3-cell form factor and connector used in the ThinkPad E480, E490, E580, E590, E14 and E15 Gen 1 chassis.

How is the 45Wh lithium-polymer battery installed, and what step do people often miss?

Power off the laptop, remove the bottom case screws, disconnect the old pack from the system-board connector, fit the new battery in the same orientation, reconnect the cable firmly, then reassemble — the step most often missed is fully seating the connector before replacing the cover.

After how many recharge cycles should the 3-cell pack be replaced?

The cells are rated for about 500 recharge cycles; after that point capacity will have dropped noticeably and a new battery should be fitted to maintain runtime.
