Following on from a previous post where I replaced the RTC module on a Socket 7 Motherboard, I wanted to resolve a similar issue with a couple of other Motherboards I have; a 286 and a 486. The 286 motherboard was missing the CMOS battery when I received it, and the 486 had a dodgy barrel battery that I was surprised to see had yet to leak. Time to fix them both!

The option I went for was the “Vertical Barrel Battery Blaster”. I uploaded the gerber files of the PCB to OSHPark, ordered the battery holders and diodes, and a couple of weeks later had everything ready to assemble. Quick solder job later, ready to go. I built a few extra just in case I need a couple more.

I have just been installing and testing them both today, and everything indeed works as it should. Hooray!
