Hi WotEver
So to separate the batteries , how would I do that ? do you mean to unhook them from the others and the inputs and draws and then measure the voltage. How long should they be unhooked and what would be considered a bad voltage.
For example my batteries (my new ones)
were charged a week ago and the are not hooked up to anything, so the have been at rest for a week as I have not yet installed them. Three of the batteries read 13.07 volts, one is 13.04 and one reads 12.96. Would the 12.96 volts be considered bad.
Also regarding the mixing of batteries In this case I could not mix them as my old bank is "wet" and my new batch is a gel type, so I believe that they would not work well together as they have different settings on the charge controller.
