I use Walgreens Heavy-Duty AA for my Rayovac 3-W and my Foxfury Signature...$5 for 12...with LED's, I figure it doesn't matter on the brand, because the difference in run-time doesn't even compare to the price difference (i.e. Walgreens $5 for 12 vs Energizer $8-$10 for 12)
are there aa lithium rechargeables available?
i know of the e2 but that's disposable.
What type of AA battery do you use with your Led flashlight?
