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.

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.
