So, I have an idea about battery charging..I am at the boat several times/wk doing various things and sometimes just enjoying a beer (or three)..My shore power charger is a 60a sterling Pro whatever bought from Maine. Batts are 6V FLA. Whenever I am at the boat, I’m starting to turn the charger off for a minute and then back on. The charger goes to conditioning (bulk) mode at 14.9V (depending on temp) for at least 1/2 hr. I have it timed for a specific profile but don’t remember the times. I’m thinking this helps with sulfation and maybe not have to equalize so often. This would help particularly in winter when the boat is not used as much. Obviously, keep up with water levels.. Thoughts?
