Does anyone here know whether or not rechargable batteries can be used in the River Rock 2AAA light? I have AA rechargables (Nicads) and I tried using them in my 2AA RR light without success. I thought maybe since it is kind of high powered, the 1.2 volts in the nicads weren't enough to power it, so I thought maybe the same could be true for the AAA version since it is also kind of bright for its size. I'd like to know because I don't have any rechargable AAA batts, but don't want to waste my money if it won't work. Alkalines work great, however.
