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: Connector fit the motherboard and will probably fit most models. Seems to be standard. - Worked fine on an ASUS Z390-1 ROG STRIX GAMING motherboard in an Origin computer. ## Features - CR2032 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B089RWJVZB | | Antenna Location | Everyday Use | | Battery Capacity | 3 Volts | | Battery Cell Composition | Lithium Manganese Dioxide | | Battery Cell Type | Lithium Manganese Dioxide | | Battery Weight | 3 Grams | | Best Sellers Rank | #6,678 in Electronics ( See Top 100 in Electronics ) #23 in Laptop Batteries | | Brand | LeFix | | Compatible Phone Models | ASUS, Dell, HP, Samsung | | Customer Reviews | 4.5 out of 5 stars 467 Reviews | | Item Dimensions | 1.77 x 0.79 x 0.13 inches | | Manufacturer | Lefix | | Model Name | RTC CR2032 | | Model Number | 262-CR2032-3V | | Number of Batteries | 1 CR2 batteries required.
