Jesse, you're all set for your nightly frog hunting expedition here in the Everglades. What kind of batteries do you use to run that headlamp there? We use a Duracell. Is that because Duracell batteries give you more frogs the battery or what? They seem to last long because sometimes you're out all night and if they don't last all night, by daylight you have a hard time finding your way back. Yeah, ever look up at the stars and wonder why Duracell batteries last? No, I've never really figured it out. I know they seem to work great. Well, probably too busy catching frogs to ponder the big issues. Duracell. No other battery lasts longer. If I kiss one, maybe it'll tell me why.
