I have a 99 Suburban that has been having a battery problem. If I leave the
battery connected it sometimes discharges enough to need to be jumped. I
normally use the quick disconnect I put on it every time I shut it down for
any length of time. It was so bad yesterday that I needed to jump it 3
times. I took it to Walmart and the battery was bad, the 3rd one in 2
years. Is it possible that the problem is all in the battery?
Related question, I would like to set up a dual battery system. Instead of
a battery isolator, could I just put in 2 power diodes in the charging
