deep cycle/starting battery
i have sitting around a 12v energizer "deep cycle/starting" battery ... it takes, and holds, a charge and shows good on a load test.
550 cold cranking amps
700 marine cranking amps (what's this ???)
140 reserve capacity
can't remember where i got this but the most likely place is from a car that i scrapped.
i am thinking that the 550 CCA is probably a little lame for a big 6 or v8 but would it be suitable for a 4 cyl. car (which is likely where it came from) ?
i know that there is a difference between a deep cycle and a starting (automotive) battery, but the name "deep cycle/starting" has thrown me for a loop ... is it supposed to be some sort of all-purpose battery ? and what's all this about "marine cranking amps" ?

So was it too difficult for you to supply the link?

Batteries are a compromise, like most everything else in life. You can have a starting battery with a lot of cold cranking amps, or a deep cycle that can stand up to very deep discharges. You can't have both in the same physical package.
What you have is a compromise battery. They are usually known as "marine" batteries. Their cold cranking amps are not as high, but it can stand some deep discharges too, like running a trolling motor or something like that.

Maybe not where you live, in Canada. The rule of thumb used to be a CCA at least equal to the cu. in. displacement. Sounds low to me but never tried it.
So in theory a 500 CCA should be enough for most engines. Fuel injection and electronic ignition makes cold weather starting a lot easier than it used to be. Nobody carries jumper cables anymore, and they don't need to.
Auto start batteries with high CCA have many thin plates that are more prone to damage and don't handle deep discharges. The deep cycle batteries would be ideal for use except they are very large for an equivalent auto start battery capacity and won't fit. Using an auto start battery on the other hand, in a deep cycle application will ruin it very quickly.
