Even after 500 full charges the battery still remains 60 - 70 % of it's original power. In an ADAC test a Bosch eBike battery was fully discharged and recharged 1,515 times before it retained only 30% of its original capacity and was no longer of any real use.
This means that the battery would have been sufficient for up to 35,400 miles (57,000 km) – or one-and-a-half times around the globe.
