RJR: Thank you , I never intended to replace a PS3 volt board, I just did not know what the upgrade were.
Marty: Thank You as I inspect each unit to determine 3 or 5 volt if and when I find a 5 volt I will open it up to determine which battery is install and remove all white batteries. My next question would be were the white batteries used on the 3 volt boards? I know years ago I bought several spare batteries when I bought the charger and I think they were all white and found corrosion on several of them and they were never installed in anything. That scares me what will I find when I open up the units.
