I've been through the fight for a new battery, just last week even. At minus thirty, a 12:1 compression ratio doesn't do me any favors, and the battery is critical. I don't even want to talk about what a fight it was to have a 48-month warranted battery replaced at 25 months. But when a 900CCA battery produces 433 CCA, it is buggered enough that it is no good to me any more.
"But, it still works!", says the scrawny manager who knows nothing about batteries except that they have more warranty than they should.
"So does your girlfriend!", I retort, "But it doesn't quite get the bills paid, does it?"
I should try harder to not be such a dick, but it works. He got my point, and I got a new battery, but with only 23 months of warranty. It's okay. I'll be back. Next time, he will just give me the battery.
As for your extra question Eric, I do not know. I need the temperature to start to warm up so that I can finish up with my "other" work in the garage, and then I need to tear into the Vette to see what has actually happened and what is speculation. I certainly am hoping for the best, but if I have head or block damage, I doubt that I will be able to justify the money that it will take to do it this year.
