Yes. and Yes.
Good to know!
CrossRoads:
Check price for same at pololu.com also.
Same price But thanks for the link to pololu.com (I'm a newbie, I NEED these links)

Duration will depend on how much else you have connected.
Generally, 30mA or so for the Arduino.
With NTX2 radio transmitter and a GPS receiver? Not enough info provided.non-rechargeabe AA battery is good for 2200-2500mA or so.
Individual Li Ion, like 18650, good for 2200mA at 3.7V (check the tenergy website to make sure).
Do some ground testing first; batteries become less efficient at temperature extremes.
I realize that I am not able to compute the duration of a battery, given its mah and current consumed by the load, when the battery is behind a step-up circuit. Is it the same? I mean, 2200mAh of a 1.2V battery stepped up to 5V will supply 2200mAh to a 30mA circuit? and thus last for 73.3 hours?
Thanks a lot!
