RC30-0248 Laptop Battery Replacement for Razer Blade 15 2018 Advanced RZ09-02386E92 RZ09-02385 RZ09-02386 RZ09-02886 RZ09-02887 RZ09-02888 RZ09-0301 RZ09-0313 Series 4ICP4/55/162 (15.4V 80Wh)

The battery was very simple to install. The battery life is ok but razers aren’t known for the best battery life but either way the battery’s nice and it was easy to install in my razer blade advanced 15 2018. I’m also glad it came with the tools to install it because I didn’t have screwdrivers that small.Update:After using the battery for a week and after the 3rd charged the battery life became really good. It went from dying after 30-60 minutes to now lasting about 4-5 hours. Sometimes even 6.

The battery life lasted for about 2 hours. I made sure that I did not keep the battery plugged in after 100% charged. In about 2 months, the battery started dying well before it hit 0 percent on the indicator. It would die at 60 percent sometimes

I bought this to replace my factory original battery in my 2019 Razer Blade 15 (RTX 2070), which had begun to suffer severe bloat and rendered the trackpad difficult to click. Replacing the battery was fairly straightforward, although I stripped some of the Torx screws fastening the case to the laptop when they had become stuck and difficult to turn due to the bloated battery pressing up against the case.There are a couple of minor issues, though. You have to apply a bit of force to push the battery all the way down into the bay where it lives, as it does not really slide in there well. The other issue is that the connector has a piece of foam on top, and there is also a piece of foam on the inside of the laptop case at the exact same spot. I found it difficult to fasten the case back onto the bottom of the laptop with both pieces of foam in place. I ended up removing the piece of foam that had been glued to the inside of the laptop, and it seems to work just fine now.No issues with charging the laptop, and battery life seems as expected. Be sure and run it through a couple of charge/discharge cycles with the new battery, as is common practice when replacing laptop batteries.Overall, I am happy with this product, at least for the time being.

In a 2018 Razer Blade 15 model RZ09-03006

This battery fit in my Razer Blade 15 RZ09-0301 laptop. I've never changed a laptop battery before and I was able to install it. (I do build my own desktops and have done so for 20 years.) Caveats:- The enclosed screwdrivers are very low quality and were both difficult to use and ended up stripping screws and stripping themselves too. Lesson learned, high quality electronics mini screwdriver set and new screws purchased. BTW, Razer laptops use T5 M2-3.5L screws which are quite uncommon.- The power connector is hard to attach. Or at least it was for me. My advice is to wear a headlamp so you can see what you're doing, and attach the power before seating the battery. I took off the little foam thingy so I could maneuver it more easily.Can't speak to battery life or how soon it's going to bloat again... but for now my case is flat and it closes properly!

for a razor blade base 2020 model .... battery life : if it performs as specified it's a rock solid battery. easy to install : came with a good set of pc screw drivers the T5 included. five stars for that. value money : at under 68 US dollars from order to shipped and took less then five minutes to install. only down side so far the cables from battery to plug in on mother board are unwrapped ... so cable management stuff on hand is a plus . tape plastic warp like stuff. probably just as good as razer store brand from official site.

I purchased this battery in hopes that it would work just as my 2019 RAZAR factory battery would without any hiccups and; i was sadly disappointed hours after installing the new battery, it was faulty, it died on a full charge, i check it multiple times to make sure i installed it correctly and it’s just not working.

Just got this battery replacement for my 2018 Razer Blade 15 where the original battery swelled. This replacement was easy to install, fit like a glove. My laptop recognized it right away, I had zero issues so far. I charged the battery to 100% and it is holding charge pretty good. Not sure about the longevity of this product, but I'm hopeful.Also, the two tools that come with the battery were useless. My laptop needed a T5 tool, the included is T6. Not an issue for me (and probably for most people) as I had my own tools, but thought I would mention it. It might work for other laptops, just didn't work on the 2018 Razer Blade 15. Overall, I'm very satisfied, thanks!
