The unit is a Windows-based scanner for automobiles with OBD-II engine controls from 1996-on. The tool needs this battery internally on the computer board so it keeps the CMOS date current along with other needed items. Without the new battery, the scanner would show the wrong date in the memory and the scanner software wouldn't load for use. In my unit, changing the battery required opening the case, but since my unit is out of warranty, it wasn't an issue. After gently opening the body and carefully detaching the old battery from the computer board, I installed this new battery with its sticky pad to the board and closed it. Upon turning on the scanner, I reset the date and time in the Windows control panel and restarted the scanner a 2nd time. When the scanner was restarted and the WindowsXP system booted, the corrected and maintained date loaded in the CMOS. Now the software can be used again and the scanner works well! This battery is a special, required item that has a special wire harness that locks onto the circuit board specifically for the function it serves. It is a CR2032 with tabs and wires attached because the board doesn't have a slot like other items have for the 2032 battery. The buyer only has to specify how the wires are arranged in the terminal because the pos and neg wires have specific spots in the other part on the board, just like any other battery. I was so glad to find this special battery on desertcart. It saved my used $1800 scanner from being a paperweight! Review: Not compatible with Dell Optiplex 7090 Ultra - Just writing a review so that people are aware this is not compatible with Dell Optiplex 7090 Ultra. It's the correct battery, but the little white plug is just barely the wrong size. It looks correct, but it isn't. This is not the vendor's fault, the item description does not state that the battery is compatible with this particular model of PC. But I can't find one that specifically states it's compatible, and so I'm randomly/blindly trying different brands of these cmos batteries. ## Features - We use high quality battery,manufactured by Japanese battery giant to produce the CMOS battery. - The battery comes with a standard connector,MOLEX 51021-0200 1.25mm Pitch connector.Please check the polarity of connector on 4th images and the compatibility on the description page - Connector:2 pins and 2 wires;Red(+,Posive),Black(-,Negative) - The professional anti-static packaging bag provides the safe protection on the battery product.

Installation was simple and straightforward, and my system's BIOS settings held immediately after reboot — a clear sign that the new battery was doing its job. What really impressed me was that I was able to use the same battery to revive a mini PC that had also lost its BIOS settings due to a failed CMOS. Both devices recognized the battery right away, and I haven't had any issues since. In my case, storing the equipment in cold conditions seemed to drain the original batteries faster than expected, so having a reliable replacement like this on hand is a must. Shipping was fast, packaging was secure, and overall, it saved me a lot of troubleshooting. If you have an older Dell, HP, ASUS, or Samsung system that’s acting up during boot or losing BIOS time/date — this battery is a simple and inexpensive fix. Highly recommended. ## Frequently Bought Together - LeFix CMOS Battery RTC Battery CR2032 Compatible with DELL D830 E6530 N4050 E7270;for HP CQ41 8440p G4;for ASUS S56 X611;for Samsung R467 R458,Black - QLQXQTy 3V 2032 CMOS Battery with Wire Leads and MOLEX Connector 5PACK - ARCTIC MX-4 (4 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive --- ## 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.is/products/213642571-2-pins-2-wires-bios-cmos-battery-for-dell-d830](https://www.desertcart.is/products/213642571-2-pins-2-wires-bios-cmos-battery-for-dell-d830) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-10-02*
