It's also a pain to put in. ### ⭐⭐⭐⭐⭐ Works in my Latitude 7390 2-in-1 *by Y***. on December 18, 2024* My Dell Latitude 7390 2-in-1 wouldn't remember the time of day. The light on the front edge blinked white and orange in the pattern which indicated bad CMOS battery. The wires on this replacement battery are longer than on the original, but there was enough room inside the case to route the excess length. Now my Latitude remembers the date and the light on the front edge doesn't blink. ### ⭐⭐⭐⭐⭐ Worked as expected and brought the CMOS settings back to a saved state *by R***T on March 6, 2025* Worked as expected and brought the CMOS settings back to a saved state on a Thinkpad W540. ## Frequently Bought Together - Rome Tech CMOS Battery for Lenovo ThinkPad T60, T60p, T61, W500, W510 - BIOS RTC 3V CR2032 with 2 Pin 2 Wire Cable (1-Pack) - Crucial MX500 1TB 3D NAND SATA 2.5 Inch Internal SSD, up to 560MB/s - CT1000MX500SSD1 - A-Tech 16GB (2x8GB) DDR3/DDR3L 1600MHz PC3L-12800 (PC3-12800) CL11 SODIMM 2Rx8 1.35V 204-Pin Non-ECC SO-DIMM Laptop, Notebook RAM Memory Modules --- ## 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.co.th/products/230611803-rome-tech-cmos-battery-3v-cr2032-w-2-pin-wire](https://www.desertcart.co.th/products/230611803-rome-tech-cmos-battery-3v-cr2032-w-2-pin-wire) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
