How many shifts can I get on a full charge, and is the battery replaceable?

Battery life depends on your derailleur model, but WHEELTOP systems typically deliver thousands of shifts per charge; refer to your specific derailleur's manual for exact figures. The 200mm cable length of this WHEELTOP charging cable ensures convenient access to the charging port, and while batteries aren't user-replaceable, the cable itself maintains your derailleur's factory warranty when used correctly.
