Recharging - Photo for October 21 2012
These are the latest version of the Eneloop rechargeable batteries. They are the best thing I've found for powering camera strobes. Super quick to bring the flash to full power and they've got a lot of stored juice. I only had to change out one time during a wedding. It's also nice to not be throwing a ton of regular, non-rechargeable batteries in the trash. Highly recommended.
