Battery tender hook up
What is the best method to hook up a battery tender?
Should I just close the trunk on the wire or can you utilize the cigarette charger? Any ideas are welcome. Thanks |

Use a gap in the bodywork and close it.

I just hook it up under the hood, using the poles provided there, and secure the hood one click. Then there is enough room for the wire without being pinched or damaging any weatherstripping.

I actually usually use the rear because I back my car into my garage always. I close the trunk down on the wire but it doesn't need to latch!
I do have an outlet on the side wall and may use the front instead. |

Mine is hooked up under the hood also but I run the wires out behind the hood down the passenger side fender so I can close the hood.

Leaving the hood or decklid up definitely helps ensure that one doesn't drive off with the battery tender attached.

I hard wired my 535I and did the M2 the same way. I ran the wires out of the bottom right air scoop. The wires push up into the scoop when not in use. You will need to add some length to reach though. The charging nuts come off to reveal studs that the rings go right over.
And... I have a small plaque I set on the drivers windshield wiper to remind me to unplug it.

Though not as visually obvious, if you close it just one click there is an angry red warning light on your dash that the hood is open. I prefer the hood partially closed as I also put a cover on my car. If you drive off with a red warning light glaring at you, you deserve whatever happens

Reviving an old thread... does anyone know what is needed to do the hardwire like Chuck W. did in his post? Total newb in the area. I have the BMW tender which I believe is a rebranded CTEK.
It comes with clips and cables. I'm assuming I use the round eyelet cables but then need some type of extension to get it to run to the bottom of the grill... where so I get that? Thanks |

Same here. I think this is the best way.

I'm trying to hardwire a battery tender under the hood. Found a extension that will let me connect the tender by running the wire out the grill or by the wiper area. I'm trying to avoid opening the hood each time I want to use the tender.
My problem is I don't know how to loosen and remove the two bolts that the tender connects too. It looks like a six sided star. |

I have mine wired up in the trunk (pics in other winter hibernation / battery thread). Theoretically the posts are after the battery management device the car has so it should be the same as connecting temporarily under the hood. Someone recently asked me to take better pictures, but haven't remembered to do so each time I drive the car.

I installed my Noco Genius battery maintainer the following way:
Installation notes: 1. I have an extension for the terminal connectors. 2. The nuts holding the terminal connectors are T50. 3. I added the plastic tubing to make it more cosmetic. 4. Charging is done from the hood cowling area without the need to lift the hood. |
