Hey all. I have a question about Optima Batteries. Do they have problems with it being below freezing? I have an Orange top in my 2001 Escape. Have had it since last summer. I have a Whistler digital voltmeter that is plugged into the Power Port. When I go out to my truck in the morning it reads about 10.6 VDC. Starts up fine. Drive to work (About 9 miles) voltmeter reads about 13.6VDC. Get off work at 6pm. Reads about 10.3 VDC. I noticed my stereo acts funny at high volume (Skips, repeats, and garbles). Only when cold out. I shut the sub amp off and it clears up. And the voltmeter reads about the same 13.4-6. But after running for a while. When things get warmed up no problems.
Any ideas? Like maybe something with the cd player or changer. Doesnt matter which I use. I drive mostly short trips. Tomorrow, I'll try driving to work with the radio off and see what happens on my ride home.
