Use only the original charger supplied with the battery, otherwise it can lead to an explosion or permanent damage. The disposal of used batteries must be carried out at a suitable disposal point.

The battery should always be kept out of reach of children. The use of the charger or the battery is not suitable for children.

Do not touch a leaking battery.

Leaking electrolytes can seep into the skin and cause discomfort. If battery acid encounters the eyes, do not rub it! Immediately wash your eyes carefully with clean water and consult a doctor or a hospital.
A faulty battery can lead to overheating, smoking or burning.
When the battery gets hot keep yourself and others a safe distance away from the battery. In case of damage or heat, you should avoid touching the battery. See chapter (“Environmental tips”).

Do not disassemble the battery.
The battery contains protective components to avoid danger. Incorrect handling, such as improper disassembly, can destroy the protective functions and lead to overheating, smoke and explosion.

Do not intentionally short-circuit the battery.
Never allow the plus and minus connectors to come into contact with each other. Do not allow the battery to come into contact with metal objects. It is dangerous if the battery is short-circuited. As it can lead to overheating, smoke, explosion or burning.

Do not heat or burn the battery.
An overheated or ignited battery can cause battery cells to explode.

Do not use the battery near heat sources.
Do not use the battery near an open flame or at temperatures above 60 °C. High temperatures can cause the battery to burn or explode.

Do not charge the battery near open fire or in direct sunlight.
This can cause errors or internal problems inside the battery, also damaging the protective function. It can lead to abnormal chemical reactions or malfunctions that lead to overheating, smoke and explosion.

Do not damage the battery.
The battery must not be dropped or damaged.
This can lead to overheating, smoke and explosion. Never submerge the battery in water.

Do not charge the battery directly from the socket or a cigarette lighter in the car.
High voltage and excessive current will damage the battery and reduce its lifespan. It can lead to overheating, smoke and explosion.

8.1.1.2 Battery Storage

If you do not use your pedelec for a long time, remove the battery, and charge about (60-80%) on. Store the battery separately in a suitable dry place.

Avoid direct sunlight from the sun, as it may cause it to overhead, and cause internal problems in the battery. It can lead to abnormal chemical reactions or malfunctions that lead to overheating, smoke and explosion.
To prevent a deep discharge, the battery is put into sleep mode after a certain time.
Do not extend the battery to temperatures below the permissible storage temperature of -10 °C to 35 °C. Note that temperatures of about 45 °C are common near heaters, in direct sunlight or in overheated vehicle interiors.

Do not continue to use the battery if you notice that it gets hot during operation, charging or storage, develops a strong smell, changes its appearance, or is otherwise unusual. Do not continue to use the battery and have it checked by a retailer before using it again.

8.1.1.3 Battery wear

The battery can be charged 500 times. The battery capacity decreases during this time, thus reducing the range of the pedelec. If the range is not enough depending on the capacity of the battery may need to be replaced.

8.1.1.4 Pedelec riding distance

It is best to charge the battery at room temperatures and insert the battery just before the start of the journey. The discharge cycle of the battery can be affected by:

Used pedal power
Total weight (load and driver)
Tire air pressure
Headwind
Ambient temperature
Road/underground condition
selected speed level
Slope
Battery charge level
Age
Remaining capacity of the battery
