My solution to that problem is to use a second power supply to charge the batteries, and put a diode between so that the main power supply can't charge the batteries. I set the voltage a bit higher on the main power supply, so that it will take the actual load. That also has the benefit of giving me redundant power supplies, in case the main one fails.
