Folks, the mystery is solved. Finally I got the wife'* car to jump mine.
I took it to AutoZone and we put it on the VAT. While the guy was tap dancing around the "we'll take it inside for about an hour and charge it up and test it again" boogie, I was watching the display. First off, he set the tester by telling the machine it was a 550CCA battery. I caught that and told him it was an 800, so he reset it. Was tjat an honest mistake, do you think, or is it a tactic to make bad batteries look good so they don't have to replace batteries?
As high as the voltage got was 10.50 with a -1.25A load. He was going back into his "take it in and charge it" spiel when the VAT gave its analysis. Bad battery.
I got a nice new copy of the battery I got in February, and it'* started right up a couple of times. Now I get to check out the various drains I've read about lately.
Thanks, folks, for helping me out. I didn't figure the battery was bad because it was so new. Takes me back to the adage "Don't overlook the obvious" and made me think that if it looks like a duck, walks like a duck, quacks like a duck, chances are pretty good it'* a duck.
Thanks again. Now I can start chasing down those power drains. THEN, maybe I can get in touch with that fellow who'* got the extra keyfobs and get that happening.
