I echo the comment above about rechargeable vs non-rechargeable batteries: only a profligate fool whose hobby is destroying the environment uses non-rechargeables in such a device. But why "Duracells"? You're just falling for, and paying for, the TV advertising. Those bunnies aren't compared with those using generic *alkaline* batteries - they are compared with those using zinc-carbon batteries which seem to exist purely to show Duracells up in a good light. If you must use dry cells, don't waste your money on Duracells but buy generic alkalines instead.
