Most times? I am not sure how you could loose out on either, ever.
No time spent to get normal batteries repeatedly. (driving, walking, paying...)
No money wasted on getting lots of normal 9v's.
Rechargeable's pay for themselves after 3 uses.
If you add the cost of a decent charger, after 7 uses.
Cant lose. Just get the Java ones. They arnt the best, but they get the job done at a reasonable cost.
One thing you might want to note, if you do get them (any type of rechargeable), make sure they are depleted fully before you try to recharge them, as adding charge to a battery with some left is what causes them to eventually go bad, and not able to be charged at all.
