    I have had bad luck with the dry cell batteries. After 3 years and 4 new batteries in 2 different trucks I went back to regular old fasioned acid type batteries. Both trucks the batteries quit by 2 years use. I put another new one in last april and this winter my alternator regulator was acting goofy.Wouldnt charge at idle. Went to auto electric repair shop and they put in a new 125 amp alt. It was better but still not perfect. They told me the dry cell battery are ok if you never draw them down more than 25%. And that the dry battery will ruin a alternator over time. They said if I put a regular battery back in it would solve my problem . And it did. I really didnt quite understand everything they said about how the dry cell batteries cause these problems but , after taking their advce my charging system is working better than new. Bottom line is I wont ever buy another dry cell auto battery.
    Anybody remember the Sears diehard gell battery? I had one of those when they came out too. About the same as above.

    I fell for the hype on the Optima as well. I bought a red top last year before the season started and this is going into the second year with it.

    I am not happy at all. There have been more then a couple of nights I had to stop plowing for 15 or 30 minutes revving the engine at about 2500RPM to re-charge it.

    I just replaced the alternator 2 days ago at a cost of $230.oo. I am not saying it is the fault of the battery but I barely made it home and ran the last 15 miles with no heat and the last 2 miles with no lights.

    My 1st check from this last week and I will be replacing it going back to a regular type acid battery.

    The alternator/battery guy told me that the Optima type batteries can work fairly well in average use as long as they never get discharged more than 25%.Once this happens the battery never fully recovers and its a downward spiral. Why is it Optima doesnt have a better warranty if these are so great?

    I heard that you can discharge them 75%
    It's the last 25% that they don't like.
    If you run them dead it can damage them some how.
