It worked and is still working. Just be very careful when changing the battery on the Lenovo W540 to avoid breaking anything (my plug pins were a bit loose).

I like to convert old laptop to ChromeFlex OS machines. When the motherboard battery for the clock and CMOS goes dead, people junk their machines. This is how you restore machines that are aging and fading.

I ordered this battery to replace the one on my computer. it was a perfect fit. It worked as advertised. I tested by turning the laptop off and disconnecting from power and removed the battery. After putting everything back and turning on the laptop i didn't have to fix the clock on the Cmos of the computer.

This battery actually worked (for my Lenovo e440), unlike the Rome Tech one I first bought that was dead on arrival. I opened the casing of this one, tested it, and found it to have sufficient charge.

It had the wrong connector for my Lenovo idea pad 20S-14IAP. No issue for me. I was able to move over the previous connector.

Waste of money and time. Does not fit my Thinkpad T480S and these people don't care!!!

Computer would not boot anymore. Lenovo t460s. This was the issue

Great one to one fit/replacement. Only needed to reset the time in my BIOS manually after installation. So far, no more issues with loosing clock time on my ThinkPad P70.

Worked as it should.

Perfecto, aunque haya llegado con algún retraso.

Works for my Thinkpad T450s.

works well on my lenovo laptop.
