Is anyone towing a Lincoln mkz, non hybrid? I have read a lot about how to deal with residual drain on the battery (all the new technology). What do you do to address this issue; I would like to make it simple.

All modern cars have SOME amount of residual drain. The question is how much, how long and how frequent.

When you first shut your car off, the drain could be as high as 1-3 amps, but that won't last for more than a few seconds. Once everything is really shutdown and asleep, the draw should be very small (10-20 ? milliamps).

However, many pieces of electronics will occasionally (3-10 minutes ?) "wake up", check a few things, possibly make an adjustment and go back to sleep. That whole process usually only takes a few seconds during which the draw could shoot up (100-200 ? milliamps) unless it has to turn on a motor (like with some automatic leveling systems).

The typical "goal" is to NOT deplete the battery during a 2 week, "no start" cycle. Remember this next time you park your car at the airport for an extended period of time. The only solution is disconnect the battery or have one of those new small jump packs.

You need to post this in the dinghy towing forum for better response. Maybe a mod can move it?

I have a close friend who leaves his new Cadillac in the garage for three months every summer while he is gone to summer in New York. Never a problem and no one starts it while he's gone.

Had the same problem on our 2014 Flex. I added a battery disconnect on the negative post of the battery. Attached a separate pair of 16ga wires one to the positive post and the other before the disconnect and ran the wires into the interior to an additional 12v power socket for our Patriot Barking System. No dead battery since.
