I have been an avid user of rechargeable AA and 9V for many years however with so few things needing AAA I haven’t taken the rechargeable plunge. However recently in an effort to be more green I have recently added some Eneloop Pro AAA for our Mozegear sync boxes and head lamps. We decided to go with the Eneloop Pro which have been flawless the last 3 months. They also have very low self discharge and have been lasting just as long or longer as there alkaline brothers. They have been a great addition to our package
