OR, you can remove the battery and use both battery posts. OR just use a charger once a month with the neg cable off the battery like the first option. Again, given the sensitivity of the cars electronics, it is just prudent to isolate at least the neg cable off the battery before applying an exterior source.

Last Fall the 10 Years old Canadian Tire Battery showed for the first time it was time to change it. ( Spoiler went up by itself . . . SRT6 do not have this Battery warning feature :-) )
Each time I had to put the car away for Winter( NOV to MAY ) , i disconnected the negative post before connecting the Optimate 6 Charger to it ,simply because some charger detect when the car electronic is still connected to the Battery and will not perform battery recondition with the same efficacity .
Two days ago ,I have installed a brand new Odyssey Performance Battery . . .

I have also installed this Battery Cut off between the bolt of the right fender and the Negative wire . . .

Now , all their is to do to disconnect the negative is turning that small Green Handle .
