I can't remember the last time only bought 2 or 4 batteries.
My coyote call uses---(wait for it)---11 AA batteries, 8 in the call and 3 in the remote. Now, one would think that as smart as all those designers must be, it wouldn't have been so tough to just make the remote use FOUR batteries.
The re-chargeable batteries I bought were more economical in packs of 8 so now I have 16 batteries with 11 in use. Guess I should have bought 24 --- two full sets for the call and a pair for my camera. AH-ha, now I have a plan-off to ebay to buy 8 more batteries.
Oh no, another snag in the plan. My charger only holds 8 batteries and it only charges in pairs and my camera doesn't use batteries as fast as the call and, and, and. Oh bother, what am I to do?
