I've been told it is not good to keep your battery on a charger all the time when it is parked. I've also been told not to leave your battery off a charger for certain long times (which varies depending on who is telling me).
I have two deep cycle lead batteries hooked to a smart charger/converter that fast charges when low and trickles at the top. Living in Wisconsin, we have hot summers and cold winters. Mostly, I keep the trailer plugged in to shore power at home which is powering up the charger/converter. I unplug when we travel in November and December, then plug in when we return at the start of the new year.
So, am I "resting" the battery enough, or not enough? Don't know why I'm having trouble getting a definitive answer.
I did once seem to kill a similar deep cycle battery when I left it unplugged for most of the winter. I do NOT intend to remove batteries in winter.
If you have a quality (pay a little more) maintainer, it won't hurt a lead/acid or AGM battery if connected continuously. LiPo require a specialized charger.
A Trickle charger is an old style low amp charger that will harm batteries because there is no "controller" to reduce amount of charge when the battery is topped off.
Most batteries only need to be maintained once a month in warmer times. In the winter, I leave my maintainers on full time. As long as your converter has a "smart" charge system, your batteries should be fine.
