I should've been more clear with the question. I was refering to the radio batteries, not the car batts. I recently tried a set of cheap Energizer 1700mah AA nimh and after 2 hours of Tx use were down to 9.7 volts on the display. What's the best batt to use in the 3PK? Can I use the supplied wall charger to charge nimh AA batts while loaded in the radio?
