Power = Volts X Amps (joules per coulomb x coulombs per second = joules per second = watts)
12V 0.9A = 10.8W
24V 0.45A = 10.8W
2 batteries, equally matched in series will supply half the power each - 5.4W
2 batteries, equally matched in parrallel will supply half the power each as well.
1 Battery will suppy all the power.
2 batteries lasr twice as long as one as you'd expect.
How long for one or two batteries depends on the capacity.
