Dose anyone experience this? Well if you have any type of wet storage battery you will have some amount of "Calcification" of the battery. This is for the most part what kills any wet storage type battery from the time they have been made.
So yes you should have a "Charger" that has this cycle in it, if you have a "Good" charger it will have 4 different cycles to the charge, a standard voltage, and high voltage (decalcification) and float, and a low (maintaining) level.
So i hope this helps and good luck and Happy Camping
