Darin P.wrote a review of Black Diamond NRG Rechargeable Battery Kit on February 1, 2012
Two Stars - for this reason. I work with a crew who spends almost all day inside big pipelines doing work. Every one of them wears a Black Diamond Icon because you can get this rechargeable kit for it, and it'll last all day. Unfortunately, I thought I'd be really cool & buy the new model of Icon. The new model takes four AA batteries, and it doesn't appear this rechargeable battery kit will work. If you buy this kit for your Icon, make sure it's a 3-battery model.
