• Use only original batteries or certified replacement batteries.

• Check the battery for visible damage such as cracks or dents.

These instructions apply to all e-bike users and ensure safe operation.

Avoiding Deep Discharge

A deep discharge can permanently damage your battery. Never discharge the battery below 20%. Deep discharges make handling difficult and reduce capacity. Lithium batteries can oxidize during a deep discharge, which negatively impacts the lifespan. Statistically, deep discharges often lead to irreparable damage. E-bike batteries should never be discharged until the voltage drops completely.

• Do not let the battery drop to 0%.

• Recharge it in a timely manner to prevent deep discharge.

Note: A battery that is regularly maintained remains powerful and safe for longer.

These tips are relevant for all e-bike users. You can implement them easily and benefit from a longer battery life. No matter which model you ride – proper care protects your battery and ensures more fun on the road.

Charging Your E-Bike Battery Correctly

Charging at Room Temperature

You should always charge your battery at room temperature. You achieve the best results when the temperature is between 15 and 25 degrees Celsius. Extreme temperatures damage the battery and reduce its lifespan. If your battery was outside and is very cold, let it get used to room temperature first. Do not charge the battery at outdoor charging stations if it is below 10 degrees Celsius outside. Manufacturers recommend storing and charging the battery indoors. This keeps performance consistent and prevents damage.

• Charge the battery at room temperature (15–25 °C).

• Avoid charging in freezing temperatures or extreme heat.

Tip: A battery that is charged at an optimal temperature lasts longer and delivers more energy.

Partial Charges Instead of Full Charges

You can extend the lifespan of your battery if you do not always fully charge it. Modern lithium-ion batteries have no memory effect. Partial charges between 20% and 80% are ideal. Small charging intervals minimize wear and ensure better performance. Charge your battery after every ride if the charge level is below 80%. This keeps your e-bike always ready for use and the battery ages more slowly.

Preventing Overcharging

Overcharging can severely damage the battery. Improper charging is dangerous and can lead to accidents or even fires. Do not leave the battery on the charger unnecessarily. Modern chargers stop the charging process automatically, but you should still check regularly. Reports show that overcharging and deep discharge can lead to irreparable damage.

Note: Check the battery regularly and use the original charger to avoid risks.

Protection Against Heat, Cold, and Moisture

Battery Protection in Cold and Wet Conditions

You protect your battery best when you keep it away from cold and moisture. Modern batteries have a battery management system that reduces damage from low temperatures.
