Quoted from slawnski:

if it has batteries, for example- do I get it reassembled at home and plugged in - then change batteries?

Cut off the battery from the MPU board - NOW!

Once you start playing the game, that old battery will warm up and puke all over your MPU board, ruining it.

Just clip the battery off now.

You don't want a change in temperature causing the battery to puke.

You can solder on a remote battery pack at any time in the future.

Quoted from slawnski:

HEN cut the battery off the board to save whatever setting are on the board already

Don't worry about saving any settings, just cut the old battery off NOW.

Looks like the battery was replaced- but not before some board damage occurred

Yep, get rid of that replacement battery - NOW

Quoted from slawnski:

So the corrosion/damage will continue even with the battery removed? UGH

You have to do some work to clean it up (Williams example, but you will get the picture):

https://pinside.com/pinball/forum/topic/vids-guide-to-bulletproofing-williams-system-6

The battery 'acid' is actually alkali, so you clean it with acid (SnoBol ....) to kill it.

You might have to remove components you can't clean under.

You might have to sand away flaky green coating that is hiding corrosion.

You might have to coat over the cleaned areas with nail polish to hinder further corrosion.

With the battery off the board I have some time - right?

With the battery removed you are in pretty good shape.

The corrosion will continue slowly. Sometimes you clean it and a little bit comes back a few years later, anyway.

Keep the board cool and dry until you are ready to have a go at it.
