My bike's range seems much shorter than it used to be, or the battery dies very quickly. Is there anything I can do?

Reduced range or power is often a sign of natural battery aging, especially if your battery is over two years old. Like all rechargeable batteries, performance degrades over time with use and age. We no longer offer services like cell balancing or deep testing to try and restore capacity. The solution for significantly reduced performance due to aging is to replace the battery with a new one.
