Installing battery tender
Has anyone installed a battery tender in their SD? I don't use my truck every week and I'm considering installing a battery tender or just the cables in my truck to keep the batteries charged up. I mostly use my truck on the weekend, but lately I've been travelling a lot and it will be 3 weeks between uses and I'm worried about the batteries.
Edit - the truck is stored outside.
Thanks!

I installed the BatteryMINDer Ring Terminal Assembly on my passenger side battery:
I plug in to the 1.5 Amp Maintenance Charger-Desulfator when not driving. I use these on all my vehicles and small engines. All are outside except the small engine and motorcycle. Been using these for over 10+ years -- No issues.

Joe - thanks. That's pretty much what I was considering, but wasn't sure if running the battery tender cables from the charger was safe or if there was a better way of setting it up.

I had wondered about a solar charger too since I want to put a dash cam in and run it when parked. Thought that might be a good way to keep the batteries topped off. Figured I could try it inside the windshield with a sunshade behind it so it was less obvious.

Exactly what I was going to suggest. I've installed this pigtail on 3 motorcycles and 2 lawn tractors. Makes it easy to circulate a couple of tenders among multiple machines.

I used the above one in my 7.3 for a couple of years. I was just running the extension cord under the hood to the charger. Through the grill.
NO problem with rain or snow
I would plug it in when the truck will sit more then 2 weeks

I've installed just the cable to the passenger side battery on my old truck as this was to be the main battery. Then I just hung it just out the hood so that I could just plug in with out opening the hood. I have not attached the harness to my 17 as of yet but I will soon. They make a small weather proof tender if it's going to be outside, but I would plug the extension into a ground fault just to be safe.

The batteries are electrically connected, so connecting to one is also a connection to the other. No need for two connections.

No. Since the batteries are connected in Parallel you only need to connect to one battery. Running your batteries in parallel doubles the capacity (amp hours) of the battery while maintaining the voltage of one of the individual batteries.
