your smarter then me lol....but heres sum numbers

yellow top
cca - 650 to 900 (depending on size)
ah - 55 to 75 (again, size matters)

red top
cca - 670 to 1000(this is at 0 degrees) (size matters)
ah - cant really find any numbers, i would expect to be around the 70s

stinger sp1700 power2 db (battery i use)
cca - 1200 (1700 5 second cranking)
ah - 72

the red top is generally cheapest, then the yellow top (usually under or around 200). expect to pay around or over 400 for a stinger sp1700.

however the sp1700 is an extremely large battery (altho not nearly as big as a sp2150) i did put the battery in the regular gm spot. but a few modifications and moving of components (abs controller) had to be done to fit it in.

for drop in replacement go yellow or red top
