Battery on trailer breakaway switch

I have a question about the break away system.
I bought a new 16' landscapers type trailer in the late '90's. It had the breaker away brake system on it, with the small square 12 volt battery on it.
After a couple of years or so. I wondered about how the battery was holding up. So I took it in to my heated shop for the winter, thinking that it might need charging. It did not need charging, and was in good shape.

A few years later I bought a new flat bed, it also had a break away break away system on it. But this one has touch pad type push buttons on the battery box, to check the battery. But I find that I don't unplug the battery when the trailer is not in use, the battery will run down.
Are all of these like this? I find this is a pain to remember to do.

Thanks,
Dusty

Cheapest way is to ditch the separate battery and run the breakaway switch's wire straight to the house battery. (This is how I would do it if it was mine.)

Best way is either the above, or the Trik-L-Start.

Both of those, you do one time and forget it for ever after.

You know what I’ve been studying this I’ve never paid attention to it. This is in a horse trailer with living quarters my truck has two plug outlets one is the smaller 6 pin in the truck bed and the other is factory on the bumper . If I use a adapter and go from the bumper plug I would have a accessory wire , I believe it would charge from the truck when driving. Just trying to figure the cheapest and best way thanks for the advice that’s why I posted here there’s a lot of knowledge.

Do you mean have a dedicated battery for the break away what you will manually charge periodically...that seems like the worst idea.

If you forget (and eventually you will), odds are you wind up with a dead battery in case the system is needed.

Ok

DrewE's suggestion of the Trik-L-Start is actually the best and easiest solution if you want to keep separate batteries. I had forgotten about it. When I had a motor home, I use the Trik-L-Start to keep the chassis battery charged when plugged in for extended periods. Worked like a champ. Permanently install it and forget it. (It has the battery isolator function built in.)

That would be the way to go or a wire from the house battery with a diode in-line.

The big advantage of the Trik-L-Start over a wire with a diode is that, should you have the breakaway switch activated when unhooking the trailer and dry camping, the breakaway system won't drain the house battery down. If it's going to drain the house battery, there's no reason not to wire the whole thing there and eliminate the little battery altogether; with the diode you would have all the disadvantages of having a single battery (like most travel trailers and fifth wheels do) and none of the advantages (one less battery to worry about).

Thanks everyone just thinking about no big deal.
