Hi. Lurker but rare poster.

I rescued this 386 from the dumpster at work.

First things first. I want to fix the dead CMOS battery.

Luckily, it's this external plug in type.

I did some searching but didn't find a newly available replacement for this cheaper than this

What works?

Goals with this are an ultimate circa 1992 build / gaming rig. That was my sweet spot for DOS gaming.

You could get an LS14250 with axial leads and reuse the 4-pin female 0.1" connector. Cut off the dead battery and strip back some of the wire. Wrap the wire around the new battery leads and cover the exposed wire with electrical tape or heatshrink.

Hi, inside my 486 PC I had one just like that, inside the black box was one of these batteries:

I ended up using one old coin battery holder just like in this post Old 486 CMOS Battery Low and it worked just fine, it was way cheaper 😉

Hooray! I picked up an LS14250 and taped the wires as Auzner described. Works great!

Thanks!
