In short: charge the battery at room temperature with the original charger, avoid leaving it empty or full for weeks, and keep it indoors in winter. That way it can last 5–7 years.
How an e-bike battery works
Almost all e-bikes use lithium-ion batteries, like a phone's but much larger: 300 to 800 Wh. A built-in circuit (BMS) protects them from overcharging and deep discharge. On average they last 500–1,000 full cycles before dropping below 80% of their original capacity. A cycle is one charge from 0 to 100%: two top-ups from 50% count as a single cycle.
How to charge it
- Use only the original charger or one approved by the manufacturer. The wrong charger can damage the battery and void the warranty.
- Charge at room temperature, between 10 and 25 °C. If you come in from the cold, wait an hour before plugging in.
- Charge on a hard surface, away from heat sources, curtains and flammable materials. Do not leave it on charge for days.
- No need to wait until it is empty: lithium batteries have no «memory effect». Frequent top-ups are fine.
- A full charge usually takes 4–6 hours.
How to store it
- For breaks longer than 2–3 weeks leave it at 40–60% and check it once a month.
- In winter keep it indoors, even if the bike stays in the garage. Cold does not ruin it, but charging below 0 °C does.
- In summer keep it out of the sun and out of a parked car: above 40 °C it ages much faster.
Cleaning and transport
- Clean the bike with a damp cloth. No pressure washer: high-pressure water gets into the connectors.
- You can ride in the rain: batteries and motors are splash-proof. Do not submerge the bike.
- On a car rack, remove the battery and carry it inside the car.
Warning signs not to ignore
Stop using the battery and contact us if it is swollen, dented after a fall, very hot to the touch, leaking or smells. Do not try to open or repair it yourself.
When to replace it
If range has dropped by more than a third compared with a new bike in the same conditions, it is time to consider a new battery. It takes a few minutes to swap and usually costs €400–900, depending on brand and capacity. Spent batteries do not go in household waste: return them to the retailer or a recycling centre.
