That work ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good batts *by T***K on February 20, 2026* Not sure for how long, but they work. They replaced the old cmos in some ancient NUCs and are doing well, so far. They definitely work. ### ⭐⭐⭐⭐⭐ Worked for what I needed. *by W***R on January 4, 2026* Worked for what I needed. Replaced CMOS battery ### ⭐⭐⭐⭐⭐ Awesome deal on some high quality NUC6CAYH batteries. 3.35+ volts *by M***W on March 8, 2025* After if did my first NUC I got drafted into fixing a number of them. This is a pack of 10 NUC specific CMOS batteries that just as promised tested over 3.35 volts. All the connectors were correct with reverse polarity and fit perfectly. If you’re getting a lot of crazy messages from your NUC it’s probably the CMOS battery. There’s no way to check the battery charge other than to open the machine up and get your meter out. The good news is that if you can figure out how to get to the CMOS battery in a NUC6CAYH (there's a great you tube that will walk you through this painful process)these batteries work great. You have to be careful because on a NUC the polarity on the CMOS battery connector is reversed so make sure you order the correct version. The batteries got here quickly and were charged over 3.35 volts so they should last for another 5 years. Great deal that got my NUC up and running again after I finally figured out how to get to the battery. ## Frequently Bought Together - EEMB 10-Pack CMOS Battery CR2032 3V Lithium Battery with 2 Pin 2 Wire Cable and MOLEX Connector CMOS Replacement for Alienware M11 Dell E6520 Thinkpad T40 Motherboards - 20PCS Vibration Motor DC3V 12000rpm Mini Vibration Motor Vibrating Motors for Projects Electronic Device Repair Single Board Computers Project Classroom Project Bristle Bots Cable 2in - LiCB CR2032 3V Lithium Battery(10-Pack) --- ## 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.hk/products/381282805-eemb-10-pack-cmos-battery-cr2032-3v-lithium-battery-2](https://www.desertcart.hk/products/381282805-eemb-10-pack-cmos-battery-cr2032-3v-lithium-battery-2) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-04-27*
