With that and the killswitch his main complaint was opening the hood over and over. Like I said, he’s 81 and one arm is weak lately.

I have a battery charger that I can fit under the hood after some hoop jumping. But I recall seeing some in the past that were pretty small. If it’s just a no bells and whistles two amp charger, to guess at a number, I imagine it could be pretty small.

How do you hook it to the battery terminals?

Mine just had generic loop terminals in a lead, which has a waterproof plug on the other end. I was able to just stack the loop terminals on top of my batt terminal bolts, and the negavtive goes to a nearby body ground (or negative terminal if you can't find one). Then it has the small waterproof plug you put the tender on. I have the leads on my car permanantly and just plu/unplug the tender from it when parked, which is always plugged in the wall. The tender came with traditional squeeze clamps too, but that would not be a good solution here. I think this would be a very good solution for the situation stated in the OP. Relays and cutoffs seem like way too much of an error-prone and tedious workaround.
