This battery is a great replacement for a lower capacity unit that was beginning to fail after 6 years of use. It fits the Raleigh Leeds touring bike exactly, and the higher capacity is what I need. I have done 2 x 20 mile rides on the initial charge so far and there is still life left in the battery. I am estimating that I will be able to get 50 miles out of it on flatish topography around the New Forest. That seems to be the expected distance from a 525 Wh battery.
It is a touch deeper and much heavier but fits. I will not notice the extra weight when cycling, much greater amount of energy available. Great comms, a query re posting was answered in hours. Arrived much earlier than expected.
