Time between charges is really the enemy. Not charging a motorcycle battery for just 2 months is enough severely shorten its life and performance.
Good post but some comments are in order, I think.
Note that NONE of that really applies to a healthy AGM battery.
Those only lose 1 to 3 percent of a full charge a month and sometimes less than that. An AGM is also less prone to sulphation than a wet cell.
And with a wet cell, a 15 percent loss of charge over a month is not enough to cause any significant change to it's life spam. Usually the self-discharge loss is much less than that.
SO.....connecting a charger for 12 hours or so once a month should be plenty for a HEALTHY wet cell battery.....and once every 3 months for an AGM. That is IF they are disconnected to remove parasitic loads.
And I object to the use of the term "trickle charger" even with the "regulated" description when it comes to a charger that you leave connected all the time. Part of the reason is that particular terminology is almost NEVER used by the manufacturers of small automatic smart tender type chargers.
