Default A tip for cmos battery replacement

Hello all from Dave. I bought a 486 computer and when I fired it up I found I had to reset the cmos configuration. Yes you have got it in one, the varta battery was dead. Thankfully it haden't started to leak, so I decided to fit 3 rechargeable aaa cells to make it easier to change the battery without having to remove the motherboard in the future. As it happened I found a 3 cell box for these cells from CPC so by using 2 standoff pillars of the female type each end I was able to screw the box onto a spare slot cover. Countersunk screws are required to fit the box to the pillars to avoid fouling on the cells. Extending the leads from the box to connect to where the original battery was removed completes the job. I now have a fully working computer without having to reset the bios every time I switch on.
