When?
- If it won’t be used for a long time
- Very hot or cold weather
- Cleaning day
How?
- Use only the original charger and charge under supervision.
- Don’t leave the battery in direct sun, extreme heat or freezing cold; for long storage many manufacturers suggest about 30–60% charge at room temperature — check your own manual.
- When cleaning, don’t spray water directly at electrical connections.
What does it depend on?
How often depends on how much and where you ride, the weather, the component and the manufacturer’s instructions. Instead of a fixed schedule, look for the signs above.
