We didn’t even get 8 miles in tonight.
I charged up the big battery for the bicycle lights this afternoon, took the lights off of my commuting bike and mounted them on the tandem. The battery charger said the battery was fully charged when we left the house and 8:30PM in the fast fading twilight. After about 5 miles the headlight was looking a little dim, so we turned around and headed home the most direct way possible. We just barely made it back with the headlight still burning.
We haven’t used those lights in about 5 years, so the battery was really dead. I wonder if after a second full charge it will last a little longer?
