I'm working on a mobile robot, and it needs 12 volts and approximately 3 ampere. Correct me if I'm wrong, I connect 8 AA E91 batteries in series which is 1.5 volts in order to achieve 12 volts. In order to increase the ampere, I need to connect another 8 more batteries parallel to the original 8. I don't know how much current does the batteries produce.
My questions:
1. What is the maximum current can the energizer AA E91 produces?
2. What other methods can be used to reduce the number of batteries used?
3. How long does it take to drain all the current away from the AA E91 battery assuming my device runs continuously?
I've search the data sheet of the AA E91 but I don't really understand what it means.

Thanks so much in advance. Really appreciate it.
