    ^ Maybe the connection could be a bit more eloquent though, feed the wire up through the same route the 12 volt positive cable takes? Not over the threshold of weather-proof seal.

    that’s essentially my 3rd gen scenario:

    The NOCO battery maintainers have detachable gator clips, which leave ring terminals. I find the ring terminals much more reliable than the clips.

    A battery maintainer tests the battery and tops it up as required.
    A trickle charger delivers a constant voltage which eventually destroyed several of my batteries.

    I know that, you know that. Appreciate it's a misnomer.

    Similar to the expression "flush" being used, in place of "replace" or "change" with some drain-and-fills. Technically incorrect, but very common usage.

    Or, when people refer to bolts by their required socket size, not the thread diameter. It's an expedience.

    I try not to perpetuate misnomers, if I can.

    As long as we're digressing, how about this one, regularly mangled:

    "I could care less"

    The correct expression being "I couldn't care less"., which actually makes sense.

    Used to bug me, but then I figure, what does it matter, you know (hopefully) what they're trying to say, leave it at that.

    As @Mendel Leisk said, chances are that you will not get a trickle charge, which is a dumb charger that supplies a small current to the battery indefinitely, which would eventually damage the battery.

    You can leave the Noco Genius, which is a smart maintainer, hooked up indefinitely, as it will toggle on and off according to the battery SOC. It will come on about twice a week and charge for about a day each time and then and go off and then repeat after a couple of days.

    Your fifteen-year-old car is a lot cleaner under the hood than his two-year-old. LOL

    One of those expressions that works either way.
    Like "flammable" and "inflammable" mean the same thing.

    Right, if it had said inflammable instead, you would have never had inflamed him and caused all that horrible road rage. LOL

    but that's an example that one thing is flammable, and another is inflammable. they mean the opposite, not the same

    LOL no, inflammable means flammable (material) or easily angered (person). Its anonym is noninflammable or nonflammable.
