Battery tender permanent connection

[alee0729]

Been looking at a few pictures of the red battery power distribution block that sits on top of the battery positive terminal. Want to do the quick connect pigtail when I get my car back from ED.

Can I attach a battery tender to any of the terminals in that distribution block (looks like there's 2 positive terminals?) or is there a specific one that I would need to connect to?

I assume there is only 1 negative terminal I can plug into.

Connect to the main(big ones) + and - pool,i have done this with my CTEC battery tender ,it's in the kit with the CTEC, with O- rings,and come together in one central connector and stay's on the battery.
So for the charge of my battery,i need only one click with the central connector..... super easy and never problems
BTW...when i need to charge.....open trunk....click....it takes 15 seconds....done
And importend....never forget.... remove your battery tender before the drive of the next morning

Thanks! I have it on my E46, and looking forward to putting it on the E92!

The rate that the Deltran tender charges is very low (1.25 amps max). You just need a connection that is always hot and a good ground. I use the jumper connection points in the engine compartment. Some people have installed always on power plugs in the trunk. As has already been mentioned, be sure you have a fool proof reminder to unplug before you drive away.

If you haven't figured it out already, the interior power plug is not always hot on the E9X M3 like it was on your E46.

Thanks for the tips. Didn't know about the interior power. I am going to be using the Deltran Tender Plus since that is what I'm using on the E46 now. I was going to install the perm cables under the hood until I noticed that BMW changed the shape of the jump posts for the E9x series.

Easy for me to remember the car is plugged in since I keep my cars covered. Got to pop the trunk to stow the cover so I will disconnect when I do that.
