Dear Klas and John,
Many thanks for your replies, both of which were informative. Klas I don't have
the multimeter to do that measurement, but your "guess" gives me a rule of
thumb. John, yes I need to do the actual test I guess. I don't really need 24
hours, probably 12-14 would do me - but what a good idea to make a AA sled if a
single 9v is not enough.
Thanks for sharing guys, much appreciated.
