Replacement battery for ThinkPad E series

The PISKEKAT 01AV448 is a new lithium-ion battery rated at 11.1V and 45Wh with a capacity of 4120mAh. It serves as a direct replacement for Lenovo ThinkPad E480, E485, E495, E580, E585, E490, E590, E595, E14 and E15 Gen 1 models from 2019. The unit is black and designed for plug-and-play installation without additional configuration.

Part-number cross-reference and manual guidance

The battery replaces a long list of Lenovo part numbers including 01AV448, L17C3P51, SB10K97609, L17M3P52, SB10K97608, 01AV447, L17L3P51, SB10K79606, 01AV445, L17M3P51, SB10K97607, 01AV446 and the 5B10W13887 through 5B10W13890 series. The supplier notes that buyers should open the back case and verify the original battery model number before ordering, and that the manual should be read carefully before installation.

Li-ion chemistry and voltage constraints

As a lithium-ion pack the battery operates at a fixed 11.1V and will only function in laptops designed for that voltage and the listed part numbers. It is not compatible with ThinkPad models outside the E480, E485, E495, E580, E585, E490, E590, E595, E14 and E15 Gen 1 range, nor with systems requiring a different voltage or form factor. Capacity will degrade over charge cycles as is typical for Li-ion cells.

Questions about this item

When will the 45Wh 4120mAh 11.1V Li-ion pack need replacing?

Capacity typically falls below 80 % after several hundred full charge cycles; at that point a new 01AV448 pack restores original runtime.

What limits runtime first during continuous discharge on this 45Wh battery?

The 4120mAh cell capacity sets the hard ceiling; once depleted the laptop shuts down until recharged.

How hot or noisy does the 11.1V replacement pack get under all-day load?

Li-ion chemistry runs silently and stays near ambient temperature; only the laptop's own cooling fans produce noise.
