There is none that I know of. The battery backup option was usually provided in the power supply, NOT the station chassis itself. On several that I have done that need battery backup, I have attached a 7809 9V regulator with a 1N4001 diode in series with the ground terminal to boost the voltage to around 9.6V. I have often thought of building this onto a card that would plug into one of the card slots, but I never had the time. This would create a situation like the GE station's 10V regulator card.
