NO. You can NEVER add any older battery to a new battery bank and expect the system to function at its optimal level. You cannot add a 12 volt to a 6 volt(producing 12 volts) type system and expect it to function correctly in the long run. 12 volt and 6 volt batteries have different charging design parameters. Doug
