how long does a 9v battery last - sunking, egodriver

[B_of_H]

I was asked to sit in with a band on nye and I'd like to just throw some batteries in a few pedals to make things easier. 

I was thinking about using my egodriver with charge pump, the sunking and an old marshall echohead.  Will the two 18v running pedals eat batteries really fast?

I haven't used a battery in years and never have gigged with them at all.

yes, they'll go fast.

I think batteries would last you a single gig without a problem. Unless it's like one of those 3.5 hour bar gigs I used to play in Dallas!

They are going to Die fast. You'd better place a new one before each gig

[B_of_H]

they'll last 5 hours or more though right? 

the max1044's worry me, i'll probably just have to test it out.  what a pita   luckily I have bunch of battery things left over from kits that i've never used.

What worries you about the MAX?

What worries you about the MAX?

well they use 30ma don't they?

I don't use batteries, so I really never consider that part of the data sheet.
