1 cell battery alternative to (2) CR2 batteries?
Having just taken receipt of a Contax G2 kit, I was wondering if someone makes a battery cell that is equivalent to (2) CR2 batteries stacked together. You see, my G2 body, and TLA200 flash both take (2) CR2 batteries, and was thinking that it would be easier to have (2) larger sized batteries to keep in the bag vs (4) smaller ones...
Preferably rechargeables too, if possible. I take my used non-rechargeable batteries to the quarterly city e-waste day, but prefer knowing I'm not creating a lot of waste by using rechargeables instead.
thanks in advance!
