Like all batteries an e bike battery will last longer if its looked after. Things you can do to extend the life of a battery include

1. Store the battery in a dry location and at room temperature.
2. Dont charge the battery after every ride unless you need the full capacity for your next ride.
3. If you dont plan on using your bike for an extended period store the battery at 60% capacity.
4. Try not to overload your battery as this may shorten the battery life.
5. Use a thermal battery cover if riding in cold weather.
