• It protects against overheating and overcharging.

• You avoid voiding your warranty and technical problems.

Charging at Room Temperature

Make sure to charge the battery at a comfortable room temperature. Temperatures between 10°C and 20°C are ideal. Extreme heat or cold during the charging process harms the battery and shortens its lifespan. If you have been using the battery outdoors, wait a while until it has adjusted to room temperature.

Note: Do not charge the battery in very cold or hot rooms. This protects the sensitive cells and ensures a longer service life.

Avoid Overcharging

Do not leave the battery unattended while charging, especially overnight. Remove the charger as soon as the battery is full. This prevents overheating and fire risks. While modern batteries have safety mechanisms, mindful handling increases safety.

• Overcharging can shorten lifespan.

• A charge level between 20% and 90% is considered optimal.

• You should also avoid deep discharge.

If you charge and discharge regularly, your battery stays in shape. Frequent short trips with recharging are better than rare, complete discharges. With these simple rules, you will enjoy your e-bike for a long time.

Storing the Battery

Proper storage of your battery ensures it remains powerful for a long time. You can significantly extend your battery's lifespan with simple measures. Pay attention to the correct charge level, a suitable environment, and protect the battery from harmful influences.

Ideal Charge Level

The charge level plays an important role in storage. You should never store the battery completely empty. An optimal range is between 30 and 60 percent. This prevents deep discharge and protects the cells from premature aging. Especially during longer periods of storage, for example in winter, it is recommended to check the charge level regularly and recharge if necessary.

• Store the battery at 30–60% capacity.

• Avoid complete discharge.

• Check the charge level every few weeks.

Tip: A battery with about 60% charge remains stable for months and loses almost no power.

Cool, Dry Environment

The ambient temperature strongly influences your battery's lifespan. It is best to store the battery at room temperature, i.e., between 10 and 20 degrees Celsius. Temperatures that are too low, especially below 10 degrees, reduce energy efficiency. High temperatures, such as from direct sunlight, accelerate cell aging. A constant temperature protects the cell structure and ensures a long lifespan.

• Keep the temperature as constant as possible between 10 and 20 °C.

• Avoid frost and intense heat.

• Always store the battery in a dry and protected place.

Protection from Sun and Moisture

Sun and moisture can harm your battery. Direct sunlight increases the internal temperature and disrupts chemical processes. This leads to faster aging and reduces capacity. Moisture can cause corrosion and damage the electronics. A wet battery should always be dried quickly before you use or charge it again.

• Protect the battery from direct sunlight.

• Keep it away from moisture and water.

• Dry off a damp battery immediately.

Note: Never charge a damp battery. Wait until it is completely dry to avoid damage.

With these simple rules, you ensure that your e-bike battery continues to function reliably even after a long break.

Protecting the E-Bike Battery

Protection from Cold and Wetness

You should always protect your battery from cold and wetness. Moisture and low temperatures can severely impair performance and lifespan. It is best to store the battery at room temperature and keep it dry. Temperatures between 10 and 20 degrees Celsius are ideal. If you do not use your e-bike in winter, charge the battery to about 70 percent and check the charge level every two months. Protect the battery on the go with mudguards or weatherproof covers against splash water and rain.

• Store battery at room temperature

• Ideal storage temperature: 10–20 °C

• Charge level for longer breaks: approx. 70%

• Recharge regularly, especially during long periods of non-use

• Use mudguards and covers against moisture

Tip: A dry and warm storage location extends your battery's lifespan.

Using Battery Protection

Many e-bike riders use special protective covers to keep the battery safe from environmental influences. You should be careful, however. Tests show that cheap covers often do not offer sufficient protection. Some cheap charging bags can even become dangerous because they trap heat and thus increase the risk of damage. Make sure that the battery remains well-ventilated and does not overheat.

Avoid Shocks

Strong shocks, impacts, or vibrations damage the battery. They can damage the internal structures and shorten its lifespan. You should always secure the battery firmly to the e-bike so that it does not shift. This protects the sensitive internal separator layers and ensures reliable function.

• Less strain on the battery

• More riding pleasure with less energy consumption

Tip: Use Eco mode especially on long tours or in everyday life to save the battery.

Check Tire Pressure

Optimal tire pressure reduces rolling resistance. You use less energy and increase your range. Tire pressure that is too low increases the contact patch between tire and road. This increases friction and energy consumption. Check tire pressure regularly and adjust it according to manufacturer specifications.

• Optimal tire pressure reduces energy consumption

• Pressure that is too low reduces range

• Less rolling resistance ensures longer battery life

Ride Predictively

Predictive riding saves energy and protects the battery. You avoid frequent stopping and accelerating. Studies show that stop-and-go riding puts more strain on the battery. Plan intermediate charging stations for longer tours and use Eco mode to increase range.

Note: Ride smoothly and predictively to extend the battery's lifespan.
