Review: The Right Battery for a Special Purpose! - This battery was used for a SnapOn Diagnostic Scan Tool. 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: Perfect fit - Works as intended. Glad I found it.
