Re: Battery CCA\'s?
The colder your winter, the more CCA's you need. When it gets down to -30,-40 I need a 850 CCA battery, just my experience and I won't buy anything less. Southern states can get by with less CCA's. I too had the problems with the busted battery plates from vibration. One day I went up to the mountains, shut off the jeep, got out for a few hours, got back to the vehicle and no start. Managed to push it down a hill (dumb luck, parked at the top) and it started. Parked it in the driveway at home, shut it off, tried to restart and it wouldn't. Voltmeter read 12V but when I disconnected it and brought it to the auto parts store, they tested it by putting it under a current load and it went down to 0.5V. So no wonder it wouldn't start, had to buy a new batter on the spot (or find hills to park on top of).
