I am looking for advice on how to extend the battery life on an Edge 810.
Yesterday I went out with a fully charged unit to do a 100 mile course, which I knew would be around 10 hours. I was using the Edge to show me the route via the courses.
After 6 hours it crashed and ran out of battery.
It did save half the rise's details, but I lost my navigation, so had to do a different 2nd half of the course.
Any advice would be very helpful.
Thanks
