I'm going to be very detailed and add some background about my laptop so here it goes.My laptop is a Lenovo Yoga 720, and it is a little over 3years old. I was having trouble with the battery life for the past few months and it was getting worse over time. I used to do a lot of heavy work but now I just use it for browsing and watching shows and just drains a lot over a short amount of time. The turning point was when it would drain very quickly from 100% to 15% in an hour or less. The reason why I say 15% is because it shuts down at 15% and not at 0% as you'd expect. I can honestly say that the battery drainage happened AFTER A MAJOR WINDOWS UPDATE (which even affected some of my function keys) and thats were it slowly went downhill.During the time I contacted Lenovo (mid Jan 2021), the battery was in back stock + no guarantee that the manufacture was going to be shipping out this laptop battery with no estimated time/delivery. I found a website (i'm not sure if it was legit or not but) where the manufacture has STOPPED production on the battery. (it is possible that it is subject to change but who knows)So I decided to go with this one. A little hesitant because there was very few reviews but I decided to go with it and it worked perfectly! Its a quick and easy 10minute~ installation (just purchase small screws drivers if you don't have any) and it was good to go! The battery life was extended to 4-6 hours and the battery was able to reach down to 0%. It does not shutdown at the 15% mark anymore. oh and it charges quickly too :)Overall: If you have a Lenovo yoga 720 and need a battery replacement, this is a good substitute for your laptop. it works perfectly fine. Depending on what work that you do on your laptop, don't expect it to reach a full battery life expectancy from the first time you purchased your laptop. This battery definitely extends it's life a little while longer.12/26/2022 update:after almost 2 years with this, battery is still going good! battery life has decreased a bit but it has not randomly shut off at 15% battery.

Logré cambiar de mi vieja laptop y funciona de maravilla perfectamente de tamaño

BUYER BEWARE: The connector wires from this battery to my laptop were at least 1/8th inch too short, thus preventing me from being able to hook it up to my Lenovo Y540 laptop.This company was fast to refund fortunately, but when I went to Newegg and reordered another one, the hookup wires were too short as well.I guess product unpredictably is what comes with buying after market products.

The battery itself seems to work as well as expected. It fits just fine in my 15" Legion. However, it did not come with the items listed. The only thing in the package I received was the battery itself. The tools were not present. The box was still sealed, so I can only assume this occurred at the factory.If you're selecting this item among the many potential options because of the tools being included, you may want to look elsewhere. I didn't need the tools, so it wasn't that big of a deal.After this review, the seller contacted me and offered to partially refund my purchase to offset the missing tools. This was appreciated.

Delivered quickly. Fit my Yoga 720 151KB perfectly. It works fine, but I have to say the directions were a bit confusing and difficult to follow. I think they advised several cycles of discharging to 3% and fully recharging. As a practical matter, this is a little hard to do, but I'm sure it's good advice.

Great replacement battery that has lasted years without issues or degradation. Would definitely buy again.

This was exactly what I needed. Note, I did remove my battery from my old Yoga to verify it matched the picture before ordering. It was an easy to switch the battery in the computer. I did have to order a different bit, but I did that when I ordered the battery.

Super easy to replace. Took like 10 minutes. More expensive replacement battery than most. Have been using it about 2 months now and it only lasts about 3 hours on a full charge and thats with settings in battery saver mode. So dont expect to get the original like 8 hour battery life back.
