    I have seen a few thoughts about this on the forum but want to clarify it.....

    Where do you hook up the battery tender without the trunk light staying on?

    Just close the trunk, that's what I did. Or unplug the light

    I removed the light. It's easy.

    I hooked it up to the terminals in the engine compartment and leave the hood partially latched.

    On my 392...I make the latch latch with the blade of a screwdriver.. as it it were closed... that turns the trunk lamp off as the lamp switch is incorporated in the latch... then I just lower the deck lid until it rests on the "closed" latch... leaves the trunk open a 1/4" or so.. In the spring.. push the truck release button... the latch opens and the lamp starts working as prescribed. I "assume" this procedure will work on the Hellcat as well. But all other options work too ;)

    The trunk light is on a timer & goes out after a few minuets with trunk still ajar.

    I've been using Battery Tenders for years in the collector cars. A couple of suggestions if I may:

    1. There is enough cush in the trunk seal so that if that if you are going to the battery directly, you should be able to close the trunk fully with no problems.

    2. I make a small "pigtail" with a two conductor connection (like a flat trailer light connection but just two polarized conductors) and have it either sit in the trunk or through the grill. The other end is hard wired to the battery the hot lead in the engine bay. This way, while the car is laid up, if you want to take it out, you don't have to go through the whole clip/unclip procedure with the leads. Just unplug the pigtail.

    I'll take a picture if someone wants to see.

    I hook up under the hood and drop the power cord under the car and plug it in.

    you can place the car in Storage model or Shipping mode ( check the threads).
    just make sure the cord does not hit the belts or fans in case you fire it up.

    I have used a Battery Tender on my Harley from 1997 to now! I am on my 4th or 5th battery on an almost 20 year old bike, not bad IMO but won't last a year without a maintainer. I have had bad luck with the actual " Battery Tender" brand but have had great luck with the $27 Advance auto house brand and the Schumacher brand of maintainers over the years. The Battery Tender brand was not lasting as long as the battery it was protecting. On the 3rd tender fail with the same battery, I changed brands.

    I use the included hardwired pig tail on my Harley so I just do the quick disconnect but can't exactly figure out how to wire that under the hood of the cat permanently I use a car cover and would be nice to have the pig tail permanently hardwired with the end out the bottom of the engine bay with the quick disconnect so I don't have to open the hood every time I hit the road.
    For now, I just uses the clips connected under the hood and works well. I would think the trunk would be lots more trouble but never tried it...
    If anyone hardwires your tender please post some pics!

    My battery tender just keeps blinking charging, never goes to green anymore. I checked the fuse and it's fine, any thoughts? Is the BT bad?

    You should check the site. A lot depends on the model you have. I am pretty sure the basic BT Plus (in the metal case) has a 10 yr warranty. I have had to replace them before.

    Be sure all of your connections are really good. Clean them if necessary. If there is any resistance it will think the battery is not charging.

    When mine did this the battery was going bad. Even a new battery can have a bad cell. I agree with the post to make sure all connections are clean and tight. Only way to check the battery is to have a free load test done preferably at the dealer. I had 3 battery tenders got bad but my memory fails of what the lights were doing or not doing at that time. I say check your battery tender by charging another car and that will tell you if it is the tender or a bad battery,,,
    Good Luck!
