Perhaps your battery was defective.

I got the same thing with a CPS-1 game, 3 Wonders, I soldered a brand new battery, but it was defective, it indicated a very low voltage. Then I replaced it and re-inserted the algo to get the C-board back to life. The game is still alive.

2 battery’s have been swapped that both read above 3 volts. In fact when it suicided, the battery still had 3.1or 3.2 if I remember correctly and it was only put in a couple of months ago prior to suiciding
