Ran without any electrical connection for 4 hours so far (estimated 1 hour to go before plugging in). You get the feeling that this was custom made for my device! The only thing left to determine is whether this excellent performance is sustainable. If there are any subsequent surprises I will update.

There's no way to know it's longevity until it fails, of course. This is the 2nd one; the first was DOA and we returned it for a replacement. So far, so good.

The battery works great. Now I have an extra laptop ready to go .

Worked great out of the box and fit perfectly just like OEM item

So happy with this product & site. Only company to send proper battery. Battery works well.

I assume that this was a good battery but it did not fit my laptop. I was going to return but health issues kept this from happening. I am going to check with friends to see if it fits their laptop.

So far so good, As long as it stays charged and I don't have to keep charging it because its goes from 100% full charge to low battery 5% in 20 min. I'm good!!

The first battery was ordered August 10, 2021 and only lasted 5 months. The replacement battery was ordered January 20, 2022 and only lasted 9 months. Neither battery lasted for 12 months as warranted. So two batteries together only lasted for a total to 14 months, only two months longer than a single battery should have. Both batteries should have been warranted for 12 months. Seller refused to honor warranty on replacement battery. Down time costs money and cost savings not worth the inconvenience. These are substandard batteries. Warranty is deceptive. Spend a little more and buy a quality battery.
