Chargers and batteries

[artcarney_agr]

My question is do you guys leave your charger plugged in all the time. never have before, I would plug up and check about once a month. I'm thinking about leaving it plugged up all the time. how much would that be on the electric bill vs replacing batteries more often

I keep mine plugged up all the time, especially in winter if I don't bring them inside.

May want to make sure your charger has some sort of fuse or protection system in place should a cell go dry. My father-in-law's older on-board charger burned out a bank due to a dry cell.
