Where is a great place online to buy aa and 9volt batteries? Where i have looked so far aa batteries are about .30 each and 9 volts are about .90 each, duracell only.
I just use the highest rated nimh AA's I can find. I haven't had a problem with them in any detector I've used them in. I found a smart charger for $10 at the flea market. It takes half an hour to charge 8 of them.
Under a buck a pop for 9V probably isn't a bad price. Glad they last forever in my Tesoro.
This is one online store... there are others (google is your friend) and some really good prices available. I purchased some 123 batteries for a third the retail cost. HH RickO
