They provided a replacement and confirmed that all batteries they ship out are thoroughly tested. But if the battery dies, certainly talk to the seller. 10/10 customer service and very swift replacement.Initial review: Battery died after 6 months. Just decided to die one day. Time to buy a new one... ### ⭐ Poor Quality Cells - Avoid *by A***F on 29 August 2022* I decided to buy a replacement battery off Amazon for my blade 15, as my original one was swelling after over a year of having the device, and I couldnt wait for Razer to replace it because of Uni etc.Fast forward to now, the battery fits fine, HOWEVER its already only holding 97% charge after only a few months, which is absurd... the cells are clearly low quality and cannot withstand being used the amount they need to be, for a main computing device like this that I use every day for work and gaming etc.super disappointed overall, if you need a replacement, just go to Razer, as there wont be anything worth buying out there you can trust will work, as despite good reviews, this is a stinker and not worth putting inside a 2.5k laptop, despite costing 80 its self. ### ⭐⭐⭐⭐ Good fit for laptop, came with 0% charge *by K***3 on 14 July 2022* Bought due to bulging defective original.Battery easy to install, power connector is ever so slightly in the wrong place, less than a mm off. Got it eventually. Some of the battery mounts were bent from delivery, however this wasnt an issue and was easily able to bend them into position for screwing down.Battery came with 0% on it.. tried to boot up without charging lead and laptop failed to start.Will test battery over next 2 days, but seems to be charging fine. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/224292692-k-kyuer-80wh-rc30-0248-laptop-battery-for-razer-blade](https://www.desertcart.hr/products/224292692-k-kyuer-80wh-rc30-0248-laptop-battery-for-razer-blade) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-11*
