Every one seems to have their favourite brand, Steve...
But I've found that the consensus amongst most pro audio folk veers towards Duracell (available bulk packed as "Procell") and Eveready Energizer.
The only "no-no, ...NO!" with any Line 6 transmitter is the use of carbon-zinc "standard" AA's, (even if claimed to be "heavy duty") as your transmitters' performance will suffer.
In any case, when the sums are done, the considerably higher endurance of alkalines over "standards" very often results in the alkalines proving to be cheaper.
Watch out, though, as I've found that "bulk direct" from both of the above companies can be both dearer and less fresh than their "blister packs" of ten and twenty from local chain stores. (Truly bizarre...)
As for me, I mostly rely on Duracell alkalines, whether badged as "Procell", "Ultra", "Super" or anything else, but I have no qualms whatsoever about running a similar variety of Energizers, both of which give at least 7, but usually eight (sometimes up to nine) hours of continuous transmission at the higher (10mW) power setting.
If, like me, you have occasional gigs where either you're unsure of the overall duration required, or access for a battery swap may be difficult, you CAN buy roughly 24 hours of continuous transmission in the form of very expensive lithium AA's. (With any luck, you can pass the additional cost on to the client...)
Doing so means you forgo the use of Line 6's "fuel gauge", as lithium's will indicate as having "full" capacity until a few minutes before total collapse.
(Lithiums are also really great for still supplying current at freezing temperatures that will "kill" cheaper types.)
I recommend "quarantining" these batteries from transmitter duty as soon as they've completed a session, as there's no way of knowing how long they'll run next time.
As a result, my world includes quite a few toys, (...for all ages, ...I'd better omit any details... ) clocks, torches and remote controls that are running on ridiculously over-rated batteries!
Finally, I have encountered some folk who are happily running rechargeable nickel-metal-hydrides, (NiMH) albeit having been forced to adopt a similar discipline with respect to the consequent inaccuracy of the "fuel gauge" system.

1. which AA batteries do you use?
Any recognized brand name alkaline batteries are fine. There are some small differences if getting the last 20 minutes out of one is improtant to you. I would recommend purchasing them from a retailer that you are pretty sure gets them from a factory distributor as there are lots of counterfit batteries out there (try a quick Google search and see)
2. Do they drain while not in use, the mic is off, but the batteries remain in?
No .. they do not drain when not actually turned "on"
3. how long should they last?
Typically we see about 7 1/2 to 8 1/2 hours of continual service from fresh batteries. They seem to have about an hour's tolerance from lot to lot. Please remember that when your RED LED first comes on you have about 2 hours of life left. The led will flash when you get down to the last hour. You can decide for yourself what your tolerance for changing them out is.

Don't read that wrong. It only flashes in the last hour but it comes on when 2 hours remain.
A lot of users mistake the red led to mean that their batteries are finished but you should still have about 20% battery life left when it forst comes on.
