When a battery leaks, does the motherboard make a sound?

About this video

Four old boards from a junk box, a 286, two 386DX and a 486DX with an overdrive CPU, are powered up to see which still work, with battery leaks in mind.

Good to know: Leaked battery residue is corrosive. An old NiCd cell should come out before it leaks, and a swollen or leaking one must never be recharged. A lithium coin cell must not be shorted, heated or charged.

Why watch it

A way to test boards of unknown history before committing to repairs, across four machines from a 12MHz 286 to a 486DX with an overdrive CPU.
