A good quality battery charger is great for those times when you need a quick charge for when you left something on and killed a battery that you need for getting to work.
For charging a trailer battery at home when speed is not of the essence I would recommend a low power float charger... the "Battery tender" referred to by Lynmor.
My float charger with slowly charge a battery to full charge in about a week then maintain the full charge indefinitely. Slow charging a battery is better on the battery than a quick charge if you have the time for a slow charge.
I can leave a fully charged trailer battery in my trailer for months after which it will be about half charged. If your trailer is draining a battery in a week then you are leaving something on inside the trailer or there is something wrong... a bad battery or a large draw from the trailer of some sort. The salesman is telling you to disconnect the battery because he doesn't want to deal with the issue.
That's what we thought the first week, that we had left something on. We made sure we turned off everything we could. The only thing left plugged in was the microwave and that's only because we couldn't get to it. I'm dreading having to deal with Camping World again to see what might be wrong. We had to return it the next day after we bought it because the water heater didn't work because they left the bypass line on. But if it comes to that, I guess it comes to that. I was just hoping we could charge the battery on our own away from the camper and have that take care of things.
