IGh ! Thanks for replying I have seen the calcars site and am trying to get some real info from them by direct contact. Basically I am trying fo a stealth approach and one that is very stright forward. The batteries are not disconnected from the rest of the vehicle when you are turned off for the night but are simply sitting there in a partial stored state.

I want to sneak in the high voltage connections from an appropiate charger to the battery connectors and plug the charger into the wall.

I plan on "sitting" the charger in the trunk area with a cord to run to the wall outlet.

That way I could make a quick removal for warranty work.

This will make a minimal improvement in performance in that I will leave home with a fully charged battery after have gagued my driving so that I pull in with it near empty charge.

Thanks for the reply. I feel that more discussion will expand the topic and foster idea generation and discussion of the topic.
