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 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.

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.

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.

One of the connector pins was bent and had to very carefully bend it back. After which it began to work as expected. Time will tell. It did come with two extra screw drivers (flat, cross)

The tools provided worked perfectly for getting the back on my Razer Blade 15 off and getting the old swelling battery out. Installation of the new battery was super easy and now I have a perfectly usable laptop again! Why pay Razer high repair fees outside of warranty when you can buy this battery which come with the tools needed to replace it? It’s a no brained to me! 11/10 will be buying a battery from here again should I need one.

Is definitely the best choice for exact battery replacement. Great value for the money. Had delivery issues but this WAS NOT from the seller, it was with the amazon delivery driver.

Was not able to install this immediately upon receiving it, and once I did install it, does not work. Acts as though no battery is installed when I unplug the laptop. But alas, I am past my return window, ordering another brand from another seller. Edit: Seller reached out and refunded. Adjusted star rating to reflect excellent customer service.
