Thanks Eric for that. I've been doing a bit of searching on the internet about it. My gut feeling is that the 0.08 shouldn't be an issue, so thanks for confirming that.
I will run 4 x fully charged NiMH batteries today and see what duration the fan runs for.
I wonder if there is a simple data logger for computers to create logging graphs for test like this?
