The one I have was made in China.

How long does the battery last, or how long will the AAA batteries last?

At these runtime the light will be at around 20 percent of it originally brightness on high…. With a fresh set of AAA Alkaline Batteries, at room temperature you can expect around 120 to 140 hours runtime on the lowest setting (depending on battery brand and capacity)… out put will be down to 20% from highest brightness level (still useable). Around it medium brightness: 10 to 12 hours. High: 5 to 6 hours

Is this headlamp waterproof?

Water resistant would be a more accurate term.
