Just make 100% shure, that it is rechargeable and 3.6volt. Not 3volt non-rechargeable.
Don't eat stuff off a 15 year old never cleaned cpu cooler.
Those cakes make you sick I tell.... (never tried though)

Replace ALL the tantalun caps of the vga board, not only the exploded one, the other tantalun caps will fail eventually.

Use eletrolityc caps in place of the tantalum caps, they have similar characteristics and are more safe. I have did this in the past on a 386 motherboard that is working until now.

So wait, rechargeable 3.6V Lithium-Ion Coin batteries for cartridges and computers? Interesting.

All of my 386DX & 486 motherboards has a non chargeable external battery connector.
I'd be inclined to say that the one on this motherboard is non chargeable.
Easiest way to confirm is probably by testing it with a multimeter?

Whoa! Don't use Li-Ion unless the charging circuit is meant for it (or you like pyrotechnics with your electronics).
