Battery Minder Tender Maintainer charge/discharge behavior

My car is used infrequently, so I was concerned about it's battery health from sitting unused in the bitter cold we can get in the winters. So I bought the Xtreme charger due to Darrell's enthusiastic endorsement.

I was wondering if I can hook up the charger to the jump points in the front, or does it need to be connected to the actual battery? And also I wanted to keep the pigtails hooked up all the time, but the rings on it almost look like they aren't big enough to fit on the battery posts.

I haven't tried to hook anything up yet, just want to make sure I do things right the first time. Anyone have any advice for me?

TIA,
Connie

 

I would recommend to the actual 12 vdc battery. Although VDC claims polarity protection, its very important to ensure the polarity is correct. A few Prius have been completely fried - thousands in damage - from a jump start done improperly

 

Either way, whatever is easier for you.

 

With both the Prius and the FJ, the Battery Minder is hooked up directly to the battery. But the Prius underhood jump point will probably be fine too. Certainly easier to get to
