I have a lead acid battery on my a-frame that i use for trailer disconnect brakes. I disconnected the battery the other day leaving the bluetooth monitor connected as it always is. The battery went from the float voltage of 13.5v down to 12.5 over a period of 3 to 4 days then out of the blue dropped to 11v in a matter of around 2 hours with nothing connected except the monitor that is always connected. Then the battery oddly came up to around 12v on its own. Picture attached. Just thought someone would find this interesting as I did.
