This save me from replacing a laptop. By adding this to my laptop the battery life is amazing it fit perfectly the functionality now last days it was easy to install amazing quality and for the price was perfect

Saved my laptop and works without issues. My laptop wasn't coming on, even with the power cord, until I installed this battery. I'm glad they included the tools as well. I'm not sure that the tools will last very long, but they worked to install the battery in my computer. I would purchase again if needed.

funciona bien hasta el momento

The advertised photo has numerous certificates showing that the battery is safe and excepted by certain standards. The battery does not have any certifications, the second photo is the OEM battery that I am replacing. That one showcases lots of certificates that the battery should have. The advertising photo shows theses certs, but the one that arrived does not.

Phillips head included is too small for screws on thinkpad t460, WILL strip screws Battery is not included with screws so if your laptop doesn't come with those, as mine didn't, you'll need screws in addition. I used the screws from the backplate to temporarily secure it. Firmware works out of box, battery had >5% charge

Why did you pick this product vs others?: I've been using it for a couple of months now and its perfect. My battery life is standing and the laptop performance is great.

UPDATE, The original 2-star review below describes my poor experience with the battery. The company saw my review, offered me a refund even though the refund time had passed, and I accepted their offer. Because of this, I have upgraded the review to 4 stars because the company showed that it monitors customer complaints and--by refunding my money--showed they stand behind their product, even when it poops out. I came out even on this, and now respect the integrity of the company, so I have given this upgrade. I would consider buying from this company again. The battery came on time and in good condition. Installing it was straightforward. Previously, I only had a working external battery (AKA battery 2), and adding this dramatically improved the total battery life on my T450s. After 4 weeks, it suddenly no longer took a full charge, and as of today, it only charges to a max of 14%. Because the system shuts down when the total battery level (from both batteries) drops below 10%, the system now never goes to this new battery. So this battery died completely in 4 weeks, and did it just as the return time ran out, so I'm stuck. Not recommended.

So far so good. My Thinkpad X270 hasn't caught fire and the battery seems to be charging and reporting accurate info to the system.
