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.

Update: Seller reached out after seeing the issue and sent another battery to replace the original with the issue. Great customer support that proactively reached out and the new battery has been holding a charge and was just as easy to install as the first one.Original Review: Easy install, but it only worked for about a month and now it won't retain a charge.

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.

Seemed fine. But started swelling and cracking after only just over a year. 0/10 Would not buy again.

My razer blad 15 battery got expanded with in 1 year of buying the laptop, but this battery so far it's doing really good and easy to install. I like it

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 .
