The batteries were all charged up in December and seemed fully charged when the ZR1s fired up tonight.....and they fired up within 3 seconds with full oil pressure a couple seconds later.

I am installing the Battery Disconnect on the ZR1s tomorrow after proving the concept this winter (and every winter)

That's up to you. But, the switch will not prevent discharging, nor stop sulfate formation either. A switch will only shut off the normal "keep alive" current, but do nothing to maintain the battery at its optimum. I recon each has to chose the practical advantages vs. disadvantages and go from there. (BTW, in addition to loosing the radio pre-sets, the ECM closed loop memory is erased too. Not a biggie, I suppose, as it is self-recoverable within a short drive time.)
