Gone as in dead, or gone as in unable to even hold a charge?I'm at the dealer, first initial test shows both batteries are gone.
If the first case, in the 3.6L JL, one should expect nothing less. 99.9% of the time the two batteries are connected in parallel.** If one of the batteries is defective and dead, it may tax the other battery for "juice," in a fruitless attempt for charge that drains the good battery.
** When are they NOT connected:
- For an instant during an engine crank: cold or ESS: where the ESS battery, on its own, signals the starter to draw current from both it and the main battery after the two batteries are reconnect in parallel. (Read: the starter is energized from either/both batteries.)
- During an ESS event.
