It's been almost a year since I changed my gaming laptop's battery with this one, cero downgrades, cero battery leaks, everything works fine, sure the active time period of gaming laptop's aren't great whatsoever, but the battery reports shows no issue at all. It came also with some tools to change the battery so props to that, the installation is easy but be careful, you may want to follow along some tutorial online.

My sons Acer Nitro 5 went completely dead. We ordered a new power supply, no change. I ordered this replacement batter and it took me about 12 minutes in total to swap his laptops battery. His laptop is now working again! This battery was a perfect fit, and included the tools needed to open the laptop and replace the battery. The replacement was super easy and my son is back to his gaming.

UPDATE: Lasted 8 weeks. I asked for a replacement from the same company as I'll give them a chance. I'll update this review after I'm assured the replacement will last longer than 2 months. UPDATE: I asked the company to replace the battery and they quickly shipped me a replacement and return shipping for the defective battery. That was great. I had the new battery put in and it lasted from 9/20/25 until 11/13/25. It's holding a 28% charge as long as the laptop remains plugged in. I went to the refund page to start that process when I noticed that the refund window closed on 10/28/25. That warranty window should probably have re-started with the replacement battery but, no. I sent a message to the manufacturer via Amazon and waited a week for a reply and, again, no. I'll see if Amazon is going to support their customer or support their seller that's provided me with two faulty batteries. There are many laptop batteries for sale here on Amazon. I'd skip these guys.

Gave new life to my gaming laptop. As is the case most of the time with gaming laptops, the battery is the first thing that starts to show age within few years. This made it such a cheap fix. Happy with results. Going strong over 3 months now

The laptop is the problem this battery came with 99% life span

I checked all the numbers on my model took a deep breath and ordered. fit perfect. watched a video for Installing it, like the video a bugger to open this model but got it done. now folks if me at 81 can do this you can to

The battery works which was a great change from my old one. But only charged to 63% then wouldn’t charge any further.

After years of use laptop batteries wear down. This was an easy to install replacement. Keeps a strong charge and hours of use.
