    Solar Battery bank

    I know that it's important to have similar sized batteries with similar voltages in a battery bank, but what about CCA ratings? would adding to 10 batteries a 105 amp battery with similar holding voltage but say 545 cca instead of 650 affect overall performance?

    In case anyone refers to this in future.
    I just realized that my own solar bank- 6 years old now- consists of 12 x approx 1200 cca batteries & 20 plus Full River batteries varying between 820 & 650 cca. It has performed very well with expected performance drop off over the years, so the answer it doesn't matter... Voltage of course evens out across the bank..
