Other than Cranking Amps and Cold Cranking amps is there anything else to factor into buying a battery?
I see some batteries with high CA and CCA that are smaller than lesser power batteries . Whats up with that?

Batteries are produced to fit different applications. The "group" number of the battery tells what vehicle or what engine the battery is made to fit. A bigger battery doesn't necessarily mean it's better or stronger. Someone else may be able to explain it better than I have. Tim
well cca/ca and reserve capacity (rc) is like horsepower and torque. you can have all the HP in the world, but without torque, you will never get it out the driveway. with REALLY high CCA/CA numbers, you will likley have a low RC. RC will allow you to crank longer even if it has a lower CCA number. a diesel with a glow polug system needs a high rc number. without it, you will deminish a battery fast while the glow plugs are cycling. a Ford IDI needs in the range of 1100-1200 CA. anything above that is really over kill, and with low RC it wont be better batteries. i have found that the Trojan & Interstate batteries to be one of the best, having a good balance of CA/CCA and RC. followed by the Johnson Control batteries. last on my list would be the Exide. the later two always like to put CCA numbers on the batteries, and neglect the thought of what the battery is doing besides start the car. the diesel really needs to deliver A
LOT of current to the plugs before you even hit the starter... kkep that in mind while buying batteries. AND ALWAYS replace batteries in pairs. it take so little for a bad battery to kill a good battery and leave you somewhere you never wanted to be..
