Influence of temperature and use
Temperature and usage strongly affect the performance of your e-bike battery in everyday life. High temperatures above 30 °C cause the cells to age faster. You should not store the battery in direct sunlight or near heat sources. At low temperatures below 10 °C, performance drops and the range is reduced. It is best to store the battery at room temperature and charge it indoors.
Avoid frost and direct sunlight.
Do not charge the battery if it is hot or very cold.
Your riding behavior also has an influence. Higher assistance modes, faster riding, and hilly terrain consume more energy. The weight of the rider and tire air pressure also play a role. Over time, capacity decreases, but through good care, you can slow down this process.
Note: Proper use and storage protects your e-bike battery from rapid aging and maintains performance.
E-bike battery: Care tips
Proper charging and discharging
You can significantly extend the lifespan of your e-bike battery if you pay attention to proper charging habits. It is best to charge the battery regularly rather than waiting until it is completely empty. A charge level between 40 and 80 percent is considered ideal. If you only charge the battery to about 80 percent, you achieve more charge cycles and a longer lifespan. Avoid fully discharging the battery or keeping it at 100 percent constantly. Recharge the battery as soon as the display shows 20 to 30 percent remaining capacity.
Tip: Short charge cycles are gentler on the battery and ensure longer use.

Protection from heat and cold
Temperature has a major impact on your e-bike battery. Always store and charge the battery at temperatures between 5 and 25 degrees Celsius. Heat above 30 degrees or frost below 0 degrees damage the battery and shorten its lifespan. Never leave the battery in direct sunlight or in a cold car. Always charge the battery in a warm room in winter.
Note: Extreme temperatures can severely impair your battery's performance.

Storing the battery
If you don't use your e-bike in winter, you should store the battery properly. The ideal charge level for storage is between 30 and 60 percent. Store the battery in a dry place at room temperature. Check the charge level every few months and recharge if necessary. Avoid storing the battery full or empty.
Never store the battery completely full or empty.
Keep the contacts clean and dry.
Regularly check the charge level.
Cleaning and moisture protection
Always clean your e-bike with the battery removed. Take the battery off before washing and cover the display. Use a damp cloth with mild soapy water for cleaning. Dry the e-bike and the contact points thoroughly after cleaning. Avoid pressure washers, as water can penetrate the motor or battery.
Remove the battery before cleaning.
Cover the display.
Use a damp cloth with mild soap.
Dry all contact points carefully.
Attention: Improper cleaning can lead to damage to the battery and the e-bike.
Use the original charger
Always use the original charger for your e-bike battery. Original chargers offer the best safety and are a perfect match for the battery. Cheap third-party substitutes can lead to short circuits, overheating, or even fires. With the appropriate charger, you extend the lifespan of your battery and protect yourself from risks.
Tip: The original charger ensures safe and gentle charging.
Avoiding mistakes
Many e-bike owners make similar mistakes with battery maintenance. You can easily avoid these problems if you know what to look out for. Here you will find the most important mistakes and how to avoid them.
Deep discharge and overcharging
Deep discharge and overcharging severely harm your battery. If you run the battery completely empty, it may no longer be able to charge properly. If you always charge it to 100%, it ages faster. It is best to charge your battery when there is 20 to 30 percent capacity left. Unplug the charger when the battery reaches about 80 percent. This significantly extends its lifespan.
Tip: Never let your battery go completely empty or stay constantly full. This protects the cells and saves money.
Incorrect storage
Incorrect storage is one of the main causes of battery damage. Many repair shops report that almost every second defect in an e-bike is due to incorrect storage or incorrect charging. Always store your battery at room temperature and with a charge level between 30 and 60 percent.

No-name chargers
No-name chargers often look cheap, but they carry great risks. They usually do not meet the necessary safety standards. This can lead to overheating or even fires. Always use your manufacturer's original charger. When in doubt, ask a specialist dealer.
Original chargers protect your battery and your safety.
No-name chargers can cause irreparable damage.
Improper cleaning
Many clean their e-bike with a garden hose or pressure washer. This is dangerous for the electronics and the battery. Water can penetrate the housing and cause damage to the display or motor. Use a damp cloth and mild soap. Remove the battery before cleaning.
Attention: Pressure washers and aggressive cleaning agents damage your e-bike and battery.
Typical mistakes at a glance:
Charging the battery with the wrong charger
Cleaning with a pressure washer
Storage at extreme temperatures
Repairing or disposing of the battery yourself
If you avoid these mistakes, your e-bike battery will remain fit and safe for longer.
Myths and questions about e-bike batteries
Charge to 100 % or 80 %?
Many believe that an e-bike battery must always be charged to 100%. That is not true. You can significantly extend the lifespan of your battery if you only charge it to about 80 %. Studies show that batteries that are regularly charged between 20 % and 80 % last almost twice as long as batteries that are always fully charged.
Charging to 80 % is gentler on the cells.
The lifespan is significantly extended.
A full charge to 100 % is only sensible before very long tours.
Tip: Charge your battery to 80% for daily use. This keeps it fit for longer.
Is frequent charging harmful?
Many users think that frequent charging harms the battery. This is a misconception. You can charge your e-bike battery more often, as long as you don't run it completely empty or constantly charge it to 100 %. What is harmful is rather heavy discharge, very fast charging, long periods of inactivity with a full battery, and extreme temperatures.
Short charge cycles are better than infrequent, full charging.
Avoid leaving the battery full or empty for long periods.
Note: Regular, gentle charging is good for your battery.
Battery in winter
In winter, your battery needs special care. Cold can significantly reduce performance. Always store the battery at room temperature and do not charge it when it is cold. Take the battery inside after your ride and only charge it once it has warmed up. For longer breaks in winter, a charge level of 30 to 60 percent is recommended.
