Dentsing RC30-0248 Battery for Razer Blade Advanced 15 2018 2019 2020 2021 RTX 2060 2070 2080 RZ09-0238 RZ09-02385 RZ09-02386 RZ09-0288 RZ09-02886 RZ09-03135 RZ09-02887E92

Wasn't sure the old, bulging battery had done any internal damage aside from the apparent damage to the chassis, but as it turned out, the chassis deformation was not permanent.Removing the old battery was a bit tricky at first, as the tabs to release it didn't want to let go, but once I was able to slide it into place, the tabs cleared the retention slots and it came right out. The new battery fit like a glove, and after reassembly, everything seemed to work perfectly. The touchpad had stopped working, but that probably was a matter of the bulging battery moving the connector strip out of its socket enough to disengage if from the contacts.Screwdriver set and spudger came in very handy.

Tight fit, the cable is too long and doesn’t align properly causing the battery to disconnect.I tried to connect it in various ways but it always lifts up.No luck.

The battery fits perfect. But after 20 days, my battery started to malfunction even if I took care of it properly. After 20 minutes of use, my laptop would shutdown without warning and have a dead battery already.However, IM STILL GIVING FIVE STARS because of the customer service of this company. I told them my problem and they replied within the day telling me that I received a defective unit and that they’ll ship me a new one. I had logistic problems, and they were still very accommodating. I will update once I receive the new battery. This company is very trustworthy.EDIT: Battery they sent is working better!

I think everyone's concerns with aftermarket battery replacements is either terrible counterfeits or random name brands that grossly overrate capacity or cut corners by not having any battery management system for the cells.I'm impressed with Dentsing because they have consistent packaging and branding, and their shipping package keeps things from getting to beat up by the courier. Also, after using their batteries across several Razer Blades I can say that the capacity meets or exceeds the rated or OEM Razer ones. I've actually had these last longer than the OEM ones. Out of 4 only 1 has failed but they simply ask for a battery report from Windows and were quick to respond and ship out a warranty replacement. The new battery seems slightly different as it doesn't say Dentsing anywhere on it anymore but seems of similar quality. The warranty batter did work and I haven't had any issues after 7 days so I've been recommending Dentsing to others.

I do not mean that facetiously! I really wish you that luck. Some people who order this battery gets one that fits. But others get one with a steel edge on the right side that is too wide. I’ve heard reports that you can file this down and get it to fit. One of the pictures show how wide it is with the battery I received. The other picture shows how slightly misaligned this makes the connector, like maybe 1mm misaligned! But, it’s a ribbon cable connector and has to be perfectly aligned. I decided not to take my chance and file it down myself, and just returned this battery hoping the next one would not have as wide a right side metal protrusion.

My Razer blade 15 2019 model has experienced the batter swelled problem so I purchased this battery for a replacement. I find my local computer service to do the job because I’m afraid to break any small pieces in the laptop. The replacement process went quick and smooth. The new battery charge to 100% successfully on my laptop and it can stand for about more than 4 hours when I’m using office softwares if I unplug the charging cord. I’m very satisfy with this purchase and hope the new battery won’t swell as the original one from the manufacturer.

The first thing I noticed was that the battery cable was a little too long and when I would plug it in and then get the batter screwed in, it would pop up the connection a bit. Annoying. I eventually got it to stay connected. Battery worked for a month or so. Now it's not showing up at all. I tried to reseat it again and make sure the cable was connected, still doesn't work. And of course I'm outside the return window now. :(

I bought this as a replacement for my Razer blade 15' and installation was easy. for the frist couple of months it worked as well as my OEM battery, but now it lasts a couple of minutes on battery life before dying .
