I find it odd that no one mentioned the removal of caps (if not sealed top) prior to charging. This allows the hydrogen to freely vent from the top area that is free of acid/water mix so as not to accumulate and possibly cause an explosion when a spark occurs.
Connecting the clamps prior to plugging in the charger is a good idea but doesn't guarantee no spark if a bad connection is made but at least you wont be nearby if it does explode. Same with disconnecting, kill the power to the charger first.
Exactly! Whenever charging batteries, especially w/ high amperage, one needs to ensure that the covers are removed to prevent h2 gas buildup. Very, very dangerous.
I personally use a Deltran waterproof battery tender w/ battery connectors throughout the Winter and my tractor is always fully charged and ready to go.
