Laptop T440 T450s X240 68+ 0C52862 0C52861 45N1128 Battery for Lenovo ThinkPad T470P T440S T450 T460 T470 X270 X260 X250 T550 T560 L450 L470 45N1127 45N1734 45N1124.

The battery is large and is not flush with the laptop like the stock batteries, so it's less comfortable when using on your lap. That said, it offers much more power at a fair price.

Fit my Lenovo Thinkpad T450. Runtimes are good but not a huge difference. You have to charge and discharge 3 to 4 times to work in the battery. Price is good.

This was the worst battery I ever purchased. It only worked well the first 2-3 months. Now, I can only get about 1/2 hour on my computer with it.

Battery has extended power. Far exceeds the 4 year old original battery. Great price vs manufactures price. I would buy again and recommend it.

* Not chargeable due to non-genuineThe battery cannot be charge by my Thinkpad T450s. That being said, it is an one-time battery, coming with 75% of the battery capacity when I got it. I have updated all my system driver and still cannot charge the battery.
