Thanks again for all the input. New battery installed ans she's alive! Reindexed windows, everything looks fine except that 3 of the 4 Tire monitors are reading zero. Breathing again.

Note to all, two of the three places I went for a battery tried to sell me the wrong size/class according to their computers. Costco online tried to get me to a class 25 (way to tall) and Pep Boys had the XLR listed as a class 90, reversed terminals but could have fit. The old battery was an AC Delco class 86 and I bought a new Bosch battery class 86, perfect fit.
