I have the Ballistic 8 cell and generally it is ok and cranks fine. I hit issues on the particularly cold days in FL (OMG 45-ish degrees), it will struggle a bit, and I may have had to push start it once, I don't remember.
My biggest issue, although it was partially my fault, is that I over-tightened my positive terminal and it must have cracked the internal nut that the positive screw goes in to...so now I can't detach the positive terminal, it just spins on the inside where I can't see. It still works, but if i ever have to replace the battery it's gonna get interesting.
