I went out to start my car the other day and of course the battery was DEAD So I purchased a battery tender and have a few questions.
1. Is it safe to leave the POS terminal connected to the battery and remove the NEG terminal from the battery. Then hookup the battery tenders POS clip to the POS terminal on the battry and the NEG clip (battery tender)to the grounding bolt on the passenger side fender well.
2. Or should I just put a bolt in the POS side of the battery and hook the battery tender to the bolt. The negative I assume I could leave going to the chassis ground bolt on the fender well?
3. Should I leave the hood fully open or cracked say half way when charging? Charging will take place in a 3 car garage.
Thanks for your help
Craig

I don't own a battery tender but helped another board member that bought one.His battery was completely dead.He hooked up the battery tender right to the battery post and it would not work at all.It kept shutting off.What he needed to do was to borrow my battery charger and once the battery was fully charged,he was able to use the tender.You can hook the positive of the tender to the positive jump start terminal on the driver's side inner fender and hook the ground lead to the ground terminal on the same inner fender.They do not need to be conncected right to the battery unless you have the battery disconnected.I don't like to disconnect the battery incase of a garage fire where I need to get the car out quickly...plus the EMC won't have to relearn the block learn/intergrator again.
As far as the hood is concerned,I leave my small battery charger connected to the positive and negative connections on the driver's inner fender and close the hood,but not lock it.Every week or so I will just plug the charger into the wall without taking the car cover off.Works fine!

2002Z4CSS, Thanks for the 411. I didn't know there was a POS jump start terminal on the drivers side fender well....

I am assumming that your SS is a 2002,there is.Look for the red plastic cap that covers a battery cable connection near the fuse junction box.The ground is right there also.
In this picture,you can see a little bit of the ground terminal that the negative of the battery tender will connect to.

That is good information to know Greg. I have Battery Tenders on both of my Camaros which I leave totally disconnected when not in use. Thanks for sharing bud. Posted by SS_CarGuy (Member # 2065) on :
I have used a battery tender for many years now. My Corvette's battery would be dead in a few weeks if I didn't drive the car.
The first thing is to fully charge your battery with a conventional charger just as Greg mentioned. Then you can hook up the battery tender right to the battery terminals.........and it is not necessary to disconnect the existing cables. That is the way I did my Vette for many, many years. In fact a lot of the Battery Tenders make provisions for permanent setup/connection to the battery so all you have to do after driving your car is plug it in. The good ones have quick disconnect fittings too to make the job even easier.

Ken,you should be able to leave the battery tender on all of the time.That is what they are designed for. Posted by Sparks (Member # 2028) on :
I leave mine connected 24/7. That's what it's designed for. Also keep one connected to a couple of deep cycle batteries.

I keep my tender on 24/7 through the winter, connected to the battery posts without disconnecting the battery from the cables. The car is garaged with car cover on and hood completely closed. Never had a problem.
