I'm a photographer and I run through a lot of batteries. Here's my experience with rechargables and Tenergy in particular. (1) They are good for about 500 cycles, so instead of throwing away 500 single-use batteries, you're only throwing away one. (2) They have longer life than single-use batteries, so you're carrying less weight and changing batteries less often. (3) When you look for the cost of recharging on your electric bill, you can't find it. So TL;DR cheaper, environmentally friendly, dependable. There is no reason to ever buy a single-use battery again!
