Extremely excellent. Was having an issue with only charging to 79 percent initially, but went away with a week I think. I was told by friend this is because battery needs to calibrate to laptop to function optimally. Anyways works perfectly now and fits.Company was actually nice enough to reach out unprompted to ensure I was happy with the battery, which was very nice and I haven't seen that before.Unsure about longevity, got a low price warranty with it though and no issues past month or so.My main point though, is if it charges 79% only, don't be scared, either talk with the nice representatives or wait a week.Would want to buy from this seller again, but I probably won't have to lol

Works fine and I did like the inclusion of tool set. However, I did a diagnostic and it had just 73% compacity on full charge. Contemplating return. I was under the assumption these should be in at least good-new condition. Just unsure if the replacement would be any better. Save myself the headache right?======Update=======So I decided to get a replacement and they were able to send it to me with a quick delivery (2 days). But the most important thing is the battery compacity of the replacement, which is surprisingly great! Thank you, nearly 100%. I'm very pleased.

Working well in my T480 so far. Time will tell on its longevity but I have tlp maintaining it between 70 and 80 percent.

This battery isn't great, the readout is mediocre (see photo, compared to an original 24,000 mWh battery). If you're looking for something that you won't have to replace for awhile -- I wouldn't recommend this one unfortunately.

Swapped out failing battery on laptop and this new battery worked just fine. Good price for the product.

This is my third attempt to find a battery that is compatible with my Lenovo P52s.This time I noticed in the Amazon descriptions were values like 01AV490, etc. I looked on the battery I was replacing and matched that number as well and this one worked like a charm!Maybe I just got two bad batteries in a row, but either way, I found a good one finally.

works great !!

Just as good as OEM at a fraction of the price! 10/10 would buy again! 6 months later and still holds a charge like new!!
