9-Cell 7800mAh Laptop Battery For Lenovo ThinkPad T410 T420 T510 W510 SL410 & More

If your old ThinkPad battery isn't holding a charge like it used to, this 9-cell replacement is a solid pick.

It's got 7800mAh capacity and runs at 11.1V, so you'll get solid runtime for models like the T410, T420, T510, W510, W520, SL410, SL510, and even some Edge and L series laptops.

It's a generic unbranded battery but compatible with a ton of part numbers—think 42T4235, 42T4731, 57Y4185, and more.

The battery type is Li-Ion, color black, and it comes with a 5-year warranty.

Just double-check your model, voltage, and capacity before ordering.

Oh, and there's a Prop 65 warning, but that's pretty standard.

Brand new and ready to ship.
