Make sure they're Alkalines, I forget what the old style is called but you don't want your bass to die in the middle of the gig because you saved $1 on your battery. I get the Duracell Pro Cell packs from Amazon, they come out to $1.50 each. They're just normal Duracells but they're good quality and I like the labeling, it's easier to write the installation date on the side of the battery with a sharpie.
It's worth getting a basic multimeter or at least a tester, alkaline batteries don't die all at once, the voltage gradually sags, they read about 9.5V right out of the package and over time they'll droop to 8V, 7V, etc. I've had a lot of basses that are much punchier with full voltage and gradually lose punch and just sound kind of thin and weak until I put in a new battery again. I've had other basses that don't seem to care as much.
According to Amazon reviews, they are the same as the copperhead Duracells, just cheaper due to bulk.
12 of them are $15.09 [on Amazon].(http://www.amazon.com/gp/product/B002UGVWA4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1)
Duracell Procell 9V are my alkaline choice. They're predictable, reliable, and last long enough. This box of 12 should last years for bass. I always keep 2 in my bass case! (Usually it's for someone else who didn't bring a spare).
Lithium disposable batteries are good too. I just use the Procell because they're ubiquitous and cheap enough.
Same for rechargeables; cheaper ones might have a lower voltage. Try for yourself, and stick to the higher quality rechargeables.
