Review: Works as expected. - Works as expected, brought new battery life into my laptop. Can hold ~90 minutes of charge time. Assembly by manual, no surprises. The toolkit that comes with it is cheap, but probably can work if you don't have a better one.
Review: Bad quality for the price - I bought it because it was cheaper than OEM. The first battery wasn't even holding 80% of its charge. Then it would only last 1hr. Ordered a replacement which was fairly simple to do via desertcart customer service. But, the same thing happened, battery doesn't last more than 90 minutes of video play. I take into account that my laptop isn't functioning properly so it may be draining battery more than needed. Nevertheless, the battery never worked as advertised and I couldn't be bothered getting another RMA. Sure it lasts longer than the original that was 4 years old and only lasted 30 minutes but it's not worth it to buy this.

### ⭐⭐⭐⭐⭐ Works as expected.
*by D***A on February 10, 2021*

Works as expected, brought new battery life into my laptop. Can hold ~90 minutes of charge time. Assembly by manual, no surprises. The toolkit that comes with it is cheap, but probably can work if you don't have a better one.

### ⭐ Bad quality for the price
*by J***O on November 27, 2022*

I bought it because it was cheaper than OEM. The first battery wasn't even holding 80% of its charge. Then it would only last 1hr. Ordered a replacement which was fairly simple to do via Amazon customer service. But, the same thing happened, battery doesn't last more than 90 minutes of video play.

### ⭐⭐⭐⭐ Doesn't last as long as the original, but still a good replacement
*by P***J on April 18, 2019*

Works right out of the box. Doesn't last as long as the original battery, but is still a great replacement when the original battery is dead.
