2 - what is a good brand? I've seen Battery Tender mentioned in some posts.
3 - I read that some have a float mode, does that mean that I can leave the battery hooked up for long periods and not have to worry about overcharging?
4 - If I eventually put a solar panel or two do I still need to trickle charge at home?
5 - What if I change to another type of battery instead of the standard lead acid type that I have now?'
I have a CTek charger that I use for things other than my airstream. It’s pretty nice. Whether you need to bring your battery home and put on a charger depends on how long you’ll have your trailer in storage. If you’re going only 2 months or so between trips I would disconnect the negative connections on the battery and leave it in place as long as it starts fully charged. The LP gas detector in the trailer always draws current and will run down the battery after a while.
If the trailer will be in storage for many months, I’d do as you plan: take the battery home and keep it in a trickle charger. And, yes make sure it has ‘float’ mode.
If you’re going to add another battery you should do it while the first one is new. The 12VDC batteries are in parallel and should be “matched” so to speak.
If you’re adding solar, you should be able to leave everything in place as the solar will keep ‘em charged up.
If / when you upgrade to Lithium batteries you have to make sure your charger is compatible with that battery type as the characteristics are different than lead acid. But, Lithium’s can be left for a long time without a battery maintainer so you may not need to worry about a charger in that case. I’d still disconnect the negative leads so the battery doesn’t run down.
I don’t know if this helps.
My AS never sits for longer than a couple of months between trips. I just disconnect the negative lines and leave the battery in place.
