Yes, I told him I wanted to put the P-5 in the stock location like other FJ owners are, and he said deep cycle, so may have been thinking of the marine one.
He said the deep cycles do not do so well if just sitting there and not getting used like my Optima one is.
I explained to him though that Painless Wiring's dual battery kit states to not hook anything upto the secondary battery at all, and to hook winches, lights, ect to the stock battery only.
I know, it sounds weird, but that is the way the Painless instructions state to do it, then if you run your primary battery down (fridge on to long for an example) you can flip the in cab switch to the secondary battery and fire up the rig.
My Painless kit lets me select a position on the three way switch too that will charge the secondary battery when you are driving.
Plus I use the solar setup too to keep the main battery charged when camping.
I did contact Torch Fab on the battery box I have, so hopefully I will hear back tomorrow to see if I am stuck using another Optima in that box or not.
For sure though I am going with a Platinum P-5 in the stock location later.
Coming up on five years this July with the stock battery, and sometimes it is a little sluggish starting it on a cold morning.
