When a battery reaches totally "full" specific gravity then a minimum activity should be taking place as far as charge maintenance rate. No, 5% antimony batteries do not get along great with 2-3/4% antimonial batteries. They throw sand at each other and hit each other with buckets and shovels whether they're standing still, being charged or discharged. If you want to play musical connects and disconnects in order to have them all pull on the rope together when an inverter is in use then disconnect immediately afterward and thence recharge according to the likes and dislikes of each type of battery then fine. Such exquisite conductor-ship seems somehow out of place when playing reggae.
