Verify part number and series

Before ordering confirm that your original battery part number matches one of the listed codes such as 0C52861 0C52862 45N1125 45N1126 45N1127 45N1128 45N1129 45N1133 45N1136 45N1734 45N1737 45N1738 121500146 121500147 121500148 121500150. Also check that your laptop model appears in the compatible series list because fit varies across sub-models.

Drop-in swap restores mobile runtime

The battery fits the existing compartment without extra cables or adapters and connects to the stock charging circuit. Once installed it restores full portable operation for the supported ThinkPad models and frees you from tethering to an AC outlet. Buyers needing higher capacity or a different form factor should look elsewhere.

Questions about this item

Does the package include only the 6-cell 48Wh battery or are tools and screws supplied?

The package contains the 6-cell 48Wh Li-ion battery only; no tools or mounting screws are included.

My ThinkPad is a T460s — will the 48Wh 10.8V version fit, or do I need a different capacity?

The T460s is not in the compatible model list; this 48Wh 10.8V pack fits X240–270, T440–470, T550–560, L450–470, P50S and W550s models.

What runtime can I expect from the 48Wh rating on a T450 with a 45W CPU under typical office load?

The 48Wh capacity at 10.8V delivers roughly one hour at a 45W draw; actual office runtime varies with screen brightness, background tasks and battery age.
