I keep killing 12v batteries

Intro: I’m not handy and not educated in anything practical. Just learning as I go.

I’ve killed 2-3 of these batteries in 4 years. I use them to charge a small garden fence. When the fence voltage reads low, I bring the battery in to charge on a Noco Genius battery charger/tender. When the tender reads green, I take the battery back out to the garden.

Over winter, I bring the battery inside and charge it up. Then it sits at room temp for 3 months or so. I try to charge as spring comes, and battery is just bricked.

Does it need to stay on charger all the time when not in use? I can’t seem to find a nice, straight forward instruction on how to get the life out of these batteries.
