Better Battery Adapter Without an Interesting Name.

Posted by: dschnur on 2026-10-03 13:11:17 Here's a quick simple project: I've taken to replacing the 1/2 AA batteries in systems I restore with a CR2032 or LIR2032 whenever practical. I've tried several of the replacement adapters available today, but I've run into a few recurring problems: • Many are made overseas, making shipping to the US unnecessarily expensive. • Some don't fit particularly well and require additional brackets to hold the battery vertically. • Some don't accommodate battery sockets with wider tabs. • Availability can be limited. • Most seem to prioritize appearance over actually being useful. So I designed my own. My goals were pretty simple: • Provide a more secure fit than the current adapters. • Allow the battery to sit flat, or nearly vertical using the original bracket's clip. • Accommodate both narrow and wide battery socket tabs. • Support a CR2032 or LIR2032. • Provide through-hole pads for anyone who wants to connect an external battery pack instead. • Function over form. • And not give it an interesting name. I doubled up the board since I couldn't find a fab that could make them thick enough at a practical cost. It's not trying to reinvent the wheel. It's just supposed to be a practical little adapter that fits the machines I've been working on. What are your thoughts:
