If you normally decide at the last minute that you need to use flash, and go out and buy batteries, then rechargeables might not suit you.
No, I'm the type that will know I need plenty of battery and/or will bring them "just in case" no matter what. Also the type that would make sure they are ALL recharged before packing them. (here's the anal part of me ... I likely would be sure to bring a pack of unopened alkalines "just in case" )
As to them not lasting for a shoot, that of course depends on what/where you are shooting, your average distance from your subject, aperture in use and ISO, etc. so no, they might not last all day at a wedding, but I think you should expect to change them out at some point for an event like that anyway.
I'm thinking an average wedding or something like that and as I said above, I would likely have plenty of rechaged and alkalines as well.
My main concern is , as stated, do the crap out after a few uses / recharges? Would it be a waste of money if I was planning on a number of shoots (weddings?) and invested in rechargables only to find out I shouldn't have bothered and just stuck to throw away alkalines?
For someone who uses flash quite a bit, they are more cost-effective, and give faster re-cycle times than AA alkalines, which is what I assume you are talking about when you say you purchase batteries before a shoot.
AH HA! That's what I was looking for!!! Thank you!!!
