Yes, there is a "surface charge voltage" of around 13.6 volts which gradually lowers to around 12.6 volts when batteries are not being charged.
But that is NOT what you said in the previous post.
While it is not optimum to run your batteries down until DEAD, convenience is more important to me.
I refuse to get up at 3AM to start the generator just to keep the batteries from reading 12.0 the next morning.
If that shortens their life a little bit.......so be it.
