6-cell 10.8V 57WH replacement battery

This 6-cell lithium-ion battery delivers 10.8V and 57WH capacity for compatible Lenovo ThinkPad models. It serves as a direct replacement for original batteries such as 42T4733, 45N1001 and 42T4751. Grade A cells support fast charging and low power consumption. Built-in circuit protection guards against overcharge, over-discharge and short circuits.

Black plastic housing with integrated latch

The battery fits into the standard rear bay on supported T, L, W and Edge series chassis. A moulded latch secures the pack without tools or screws. The form factor matches the original 6-cell profile so the notebook sits flat on a desk. No additional cables or adapters are required for installation.

Replaces worn 6-cell packs on listed ThinkPads

This unit restores runtime on machines currently using depleted 6-cell batteries such as the 42T4731 or 45N1000. The upgrade is worthwhile when the original pack no longer holds a useful charge. It does not fit Slim variants including T410S, T420S, T430S, T440, T450, T510S, T520S, T530S, W500, P Series or X Series.
