How many car batteries would it take to run a reprap for about 2 hours?

Typical power requirements, with some margin, after warm up phase:

- 1.5 A per stepper
- 2 A extruder heater
- 8 A heated bed
- (0.1 A controller)


8 A without heated bed, 16 A with heated bed. With a typical small car battery (45 Ah) this means 5 hours of printing without heated bed, 2.5 hours with one.

Have you done a search? I'm sure this Q was asked before.
