I don't usually write reviews, but decided to go out of my way for this one. I purchased this battery and was able to get it overnighted to fix my Razer Blade 15" Advanced (2020). As expected, this battery fit right in, with the right screw pattern and attachment. I have had it for three days and have run through 2 discharge cycles and it appears to be operating, once again, as expected.The spudger worked well, as well, to help get the laptop open and it was nice that it included all the screwdrivers to open the laptop -- though I didn't use them as I had my own tools, I may have been slightly frustrated by the small diameter of the handles versus the torque that Razer uses for the screws. It could make it exceptionally difficult to open. The only feedback I would have for the seller would be to include wider diameter handled screwdrivers.

I used this to replace my battery in my daily laptop that i’ve had since 2019, replacement went decently however the plug-in was slightly misaligned which was not a huge issue since it still was able to hold the socket. Regular use showed that the battery was normal and functioning and I had some decent off the charger life comparable to the original battery. Issues began about 2 months after installation when my laptop would suddenly lose large % of battery, down to 0%, to which it powered off with no warning. since then, the battery won’t charge and my laptop is not tied to only being used while plugged into an outlet. i tried to reseat my battery thinking the issue was the misaligned socket, to which i found it was still plugged in and seemed perfectly fine. Nothing i’ve done fixes my issue and i’m really disappointed with my purchase.

I was pleased when the battery arrived on time. It fit just right. The battery though would not charge and I had absolutely no problem getting a functional replacement. thank you very much.

This is for the replacement of my Razer Blade 15 battery which was totally out of juice. As soon as I replaced with this new battery, I can power it on. The battery is about 10-6% from the factory. The installation said to charge it up to 95% and discharging it down to 5%. Repeat it 3 times.Overall, I’m very happy with the product with this price point.

My first review ever. Battery stopped charging in less than a year. The company reached out after my poor review. They sent a replacement battery for free so thank you! It would just be nice if there was a way to contact them. Thx

The battery was a perfect replacement for the OEM Razor battery that had EXPANDED in the case. The battery even came with the needed tools to open and quickly replace. The entire job took less than 5 minutes and works perfectly. Highly recommend.

Installed and worked fine but product did not last 6 months. Now battery will not take a charge.

I had been having trouble with my Razer 15 being able to hold a charge so I decided to change the battery. Matched up the Model # of my laptop with the ones in the description. The battery arrived quickly and comes with small set of jewelers screwdrivers. The hardest part was getting the adhesive off the old battery so we could remove it.
