How many miles depends on how many shifts. I often shift 500 times on 50 miles with RD. The front could be 2-12. I switch bikes every week in the summer, so RD battery may have 1500 shifts on it before recharging. I pay no attention to battery level.
I bought two knock off batteries from Amazon. One failed quickly.
