I recently received my new 18 ah battery for my Pro Connect. It came fully charged, though I stuck it on the charger just to make sure it was fully topped up. Anyway today was the first chance I had to try it - my daily commute to work; a 22 mile round trip. My initial feelings are that it is somewhat sluggish, on average around 1.7 mph slower than my old 10. Has anyone else found the performance of the new battery somewhat less than expected?
