lithium batteries
they last longer and work in colder weather. and they cost twice as much
Still waiting for winter too.
Temp on the water last weekend was 60F, very unusual for NS. The WP of course worked like a champ. This weekend is forecast to be around 36, I’ll try again.
Optio WP Batteries
Just got back from 3 days of skiing at Alta. Kept the Optio in an outside pocket in my ski jacket where it got plenty cold at 10,000 feet. I didn’t need to re-charge once the whole weekend. So, my experience is that the batteries are not affected by the cold, I suppose your charges may vary. (It was a dry cold.)
