Pinball machines!

Some pinballs use 3 AA batteries for their CMOS ram backup. Operators usually knew about them...homeowners that have machines...don't. Usually when I customer calls us about a problem...chances are the batteries are 10 to 15 years past date and destroyed the board. I mean...I've had boards I've had to throw away because the battery damage was so severe it could not be repaired.

I've seen every brand of alkaline do this...usually long past expiration. Super heavy dutys I've seen split a seam..but rarely ever cause corrosion damage.
