Rome Tech has just about every battery type you'll need. The biggest and most important part is making sure you get the right battery first. Rome Tech asks you for your laptop make and model and they will match you with the correct battery. If you're pretty good at working with small screws and taking apart laptop cases, then you'll save a lot of money by doing this yourself. ### ⭐⭐⭐⭐⭐ Good fit for Dell 7280 laptop. *by on Reviewed in the United States October 28, 2025* Got this to replace the cmos battery in my Dell 7280 laptop. It seemed silly to me to not just use a normal coin cell battery, but this was far easier than trying to remove the wiring from the OG battery and trying to solder everything back together. Installation was just as easy as the removal. ## Frequently Bought Together - Rome Tech CMOS Battery for Dell Latitude 6430u Dell Latitude 7300 Dell Latitude 7430 Dell Latitude 7490 Dell Latitude 7530 - Laptop Backup CMOS Battery CR2032 BIOS RTC 3V - 2 Wire Cable (1-Pack) - Crucial RAM 16GB DDR4 3200MHz CL22 (or 2933MHz or 2666MHz) Portable Memory CT16G4SFRA32A - Kingston A400 SSD Internal Solid State Drive 2.5" SATA Rev 3.0, 960GB - SA400S37/960G --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/682933384-rome-tech-cr2032-cmos-battery-for-dell-latitude-6430u-7300](https://www.desertcart.sk/products/682933384-rome-tech-cr2032-cmos-battery-for-dell-latitude-6430u-7300) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-15*
