This replacement battery pack is manufactured to OEM standards and works great. The actual batteries themselves are apparently Sanyo lithium ion. This is a fresh battery with a manufacture date of 6/2025, and 1 charge cycle. This was actually the second battery shipped; the first one also looked in perfect condition, but would not charge. They shipped out the replacement immediately and it arrived in a couple of days, without waiting for the return. The first one just has to be sent back at their expense within 30 days, e.g. dropped off at any Staples.

Came with everything I needed to replace my laptop battery myself. It worked the first time and has been working for many months exactly as expected. Well done product.

The battery lasted 1 year. I thought it was a problem with the laptop, but two computer people said it was the battery. Amazon says to go to company website. I can't find any way to contact them.

My laptop battery was failing, and needed to be replaced. I spent less than $100 on it used/refurbished and couldn't see spending 1/2 that or more for a replacement so decided to go with the least expensive I could find. As of now it's holding a charge and gives as good performance as the OEM that it came with when I first got it 4 years ago. It's main issue is it's not as well finished and doesn't fit well as the OEM, but for the price it's good enough. If it starts to loose the ability to hold a full charge I'll do an update, but so far I'm pleasantly surprised.

I finally found a battery for my 15" HP Spectre x360. My battery swelled up and expanded and I couldn't use the touch pad anymore. I was taking a chance doing my own repairs. But I did it and it works!!

worked very well with my laptop, I changed the battery by myself

excellent construction, easy to install, ecellent charge rate, excellent heat range, exact replacement

Perfect fit

It does not last as long as the original but I knew it before I got it. The original battery cost $150.00 this one cost me $30.00 and does the job perfectly. Fit very well on the laptop and you have a resonable good time when the laptop is not plug in to a wall. I watched a full movie on it and still had some charge left. Very good item for the price. I recomand this item.

I bought one of these batteries for my laptop T420 about 3 years ago. Recently the battery life was not lasting long enough for me so I replaced it with a cheaper battery that I found on Amazon. It did not work for my computer, so I ordered this battery again and it works well and last up to 3 hours on one charge.

the battery life is not what I expected but I am not sure what factory specs are either, but for the price it lasts for about 3 1/2 hours.

Works like new

Le produit semble bien fonctionner, la charge se maintient bien en mode veille, mais descends rapidement à l’utilisation.
