Did not have electronics in high school. Took circuits and power engineering courses in college - barely remember anything relevant. Somehow I do not think it is as easy as popping in a cap. Isn't there concern about dropping the voltage down to meet the board's requirements? Don't you have to limit the discharge rate? Seems to me this involves resistors and inductors and maybe diodes in addition to the cap. Don't you have to figure out how much energy storage is needed in the cap ???
After blowing a PS2 board with a bad battery, everything gets a BCR except PS3s. Pop it in, lube everything up, and I never need to open it up again and never need to worry about a leaking battery. For $20 or less - cheap insurance. Given my EE skill set or lack thereof, why would I risk a $500 and up engine to save $10 or $15 bucks? Ok to fix the board $200 new board, $100 technician and $75 for RT shipping - assuming you can get the board.
