Review: Great replacement battery that saved me from buying a whole new mouse - This battery saved my mouse! I have a Razer Viper Ultimate and the battery would need to be recharged almost every day. I almost considered replacing the whole mouse. I searched to see if there were battery replacements, and landed on a Youtube video that suggested this product. This thing saved me from spending over $100 on a new mouse. The only thing you need to be aware of is that this battery is physically larger than the original battery (longer from front to back), but also has a larger capacity. Replacement is very easy. Take your time disassembling the mouse, keep your screws in a small container to avoid losing them, and you'll be just fine. Took me about 15 minutes. Review: Brought full functionality back to my dead Viper Ultimate - Worked seamlessly with my Viper Ultimate making it work like brand new again. ## Features - 💐Please ensure both model and battery part number are matched with your device before purchasing( you can find related information in product description).
