We wrote about this last week - check the posts. I highly recommend the Soneil Desulphator / charge maintainer. I would charge most of the way with the stock charger with Landis controller, then switch on the Soneil to top them off & maintain them. Either way I would not leave the tractor plugged in long term. You would waste electricity constantly topping them off and could over charge them.

Subject: (ET) charger, desulfator
I have a set of new batteries, and is like to take better care of them
than my last set. I currently charge with the stock charger, but with
the Landis charger controller. I was thinking about adding in a
battery maintainer/desulfator to help with keeping the batteries
fresh. Any thoughts on these?

The second one is twice as expensive, but is also a charger, primarily
a trucks charger though.
