Hello - I was just wondering if anyone has had issues with weak batteries? I have an 11 STI, and one of my friends did a battery test to see the strength and surprisingly it was very weak. Living in a cold area, this concerns me that it may get weaker and the car might have trouble starting on cold mornings. Not sure why it would be weak. My friend suggested the stiff suspension might beat it up more than normal. Any thoughts on this?
