Replaced the main crank battery. Even with battery tender on it overnight, it showed overall health was bad (even though state of charge/voltage was good).
Battery was tested completely disconnected (to isolate from the aux battery). Aux battery was fine (around 90%).
Got a bigger Duracell battery from a local Batteries Plus ($220.80 out the door - after tax, 10% discount, and core return).
Something I didn't know until I read here in the forums is that JTs (maybe JLs as well) that come equipped with factory Aux switches come with the bigger batteries. Mine didn't, so it came with the smaller 650 CCA battery (and a spacer on the battery tray).
New one fits perfect.
Hope everyone had a great Christmas!
