Batteries typically last 5-6 years. However, this can vary depending on how much you use your e-bike. Mokdern batteries will still deliver more than 80% of their original capacity after 500 charge cycles.

To prolong the lifetime of the battery there are several procedures that can be followed. The main ones include:

1.If storing the battery for more than 2 weeks it should be kept in a cool, dry place with a 70%-80% charge remaining in it.

2.Avoid running the battery completely flat. Charging batteries when they still have 10-15% of power remaining will significantly extend their lifetime.
