The SC is going to storage for most of the winter. I know I should slightly overfill the tires, add some Sta-bil, cover the car, and add a battery tender.

I have the Battery tender junior that I will connect...

can I connect the clips directly to the terminals of the battery, or should I clip the negative clip to another source?

I have my battery tender + and - harness attached permanently to the batterys respective terminals. I then plug in the battery tender with its connector. I had the standard battery clips but I chose to use battery tender other harness . It easier to just plug in and out .

Likewise. The former owner of my SC had a Schumacher 1.5A battery tender permanently installed under the plastic cover under the hood on the passenger side with the pigtail and plug hanging out. I haven't used it this year yet but he told me it was more convenient that way.

I believe if you check the manual you will find that you should use a chasis ground not the neg battery terminal

To clarify, this is absolutely correct that this is the manufacturer's recommendation; however, once connected the negative terminal and the chassis ground should be electrically equivalent.

Battery tender reccomends attaching there terminal harness direct to the battery, since there charger is designed to only charge when there is suffient voltage at the battery. If your battery is dead the battery tender can not recharge it untill the dead battery has at least an output of at least 3 to 4 volts. Its also protected from incorrect polarity. I think if your trying to jump start the car the general knowledge is to use the positive terminal for one clamp and use a chassis ground for the other. This is to avoid any sparks near the battery that could cause and explosiion. Also note that the battery tender is a low voltage charger that is controlled by its own internal design to prevent overcharging. I use them on all my cars and motorcycles.

I have my battery tender hooked up. + to the battery terminal and the neg leg hooked to a bolt. When not in use, I just tuck it (wires) along side the battery until needed.

Update while installing my new toy, a Injen cold air intake (got from AZKaty when visting Az) the bolt I used for the neg side was one on the engine that was close by.
