A brief overview - important information at a glance:
Basics: Look for the GS symbol when buying a battery. The test mark ensures that you enjoy your battery and that all safety regulations have been observed.
A rechargeable battery costs several hundred euros, corresponding to the storage capacity, which is indicated in watt-hours (Wh). The capacity can range from 250 Wh to a current maximum of 750 Wh.
The stronger the battery, the greater the range. If your battery will not be used for a long time, remove it and store it in a cool, dry and half-charged place.
All you need to charge it is a standard power outlet.
The charging process itself takes one to several hours, depending on the power of the charger.
The lithium-ion battery
The long-life lithium-ion batteries are mainly used for pedelecs and e-bikes, as they can store more power with their high energy density and relatively low weight. Only after a few hundred charging processes can the capacity decrease somewhat. Batteries that have always been charged in the range between 20 and 80 percent last the longest. It is advisable never to run them completely empty and to charge them completely again even after a short period of use.
My lithium-ion battery is brand new - what is the best way to do it?
You should fully discharge a lithium-ion battery three times before its first use. Once it is in use, you should get into the habit of fully charging it after each use, no matter how full it may be.
General questions about the e-bike battery
How do you load properly?
Batteries must only be charged with the appropriate charger, otherwise irreparable damage may occur and at the same time all warranty and guarantee claims may expire.
How often can a battery be charged?
Roughly, one can say that in the course of a "battery life", approx. 55000 kilometres can be reached, provided it is properly maintained.
How long do I have to charge it?
The charging time depends on the capacity of the battery and the performance of the charger: Half a charge takes about one hour in the best case. An empty battery, on the other hand, needs up to 3.5 hours on the charger until it is fully charged.
What is the best way to store and transport my e-bike battery?
Your battery feels best stored in a dry environment, protected from direct sunlight and at a room temperature of about 15 to 20 degrees Celsius. The ideal charge level is between 20 and 80 percent. Charging should be done at room temperature. When transporting, you should remove the battery and store it safely.
What should I be aware of in winter?
Cold weather reduces the battery performance, so it is important to insert the battery, which is charged at room temperature, into the e-bike only shortly before you start riding. In the meantime - as long as the battery is not in use - it should be stored in a dry, cool place with 20 to 80 percent charging capacity.
What can I do if the battery is dirty?
Never use strong cleaning agents! A damp cloth is sufficient. Remove the battery from its holder and wipe it clean. Do not neglect the plug poles, which you should occasionally clean off dirt.
Where can I have the battery repaired?
A defective battery must be replaced in almost every case, as it is a complex storage unit. If you are not sure, have it checked by a specialist dealer. If the battery is definitely defective, your dealer can dispose of it appropriately.
What happens to a used battery?
An aged battery that has just reached a maximum of 70% of its previous capacity should be returned to the manufacturer. It will then be disposed of properly; the raw materials can be recycled again. Refreshing is also sometimes possible, but this should only be carried out by an expert.
How to treat the battery correctly?
One of the battery's enemies is extreme temperatures. If you bring it to your warm home after a drive through a breathtaking winter landscape, give it some time to "acclimatize" before you charge it. However, you don't need to worry if you use it in winter, because it will be reasonably warm as long as you drive.
In very low outside temperatures, you can keep the loss of capacity to a minimum by connecting the battery directly from the socket to the e-bike and riding immediately with maximum support. This also guarantees a long range for a long time.
When I run out of power on the road
Head for the nearest petrol station or restaurant!
More and more bicycle dealers, petrol stations or restaurants and restaurants offer recharging facilities, often for free. Otherwise, you can use a coin slot to get electricity for your battery. So always take a few coins with you when you plan long tours.
What types of batteries are available?
The frame battery is usually more compact and is located close to the bottom bracket on the bottom tube or seat tube. It has a low centre of gravity and can also be easily stowed away in a backpack or pannier bag. It is used most often.
Fully integrated battery
The fully integrated battery is visually unobtrusive. Protected inside the down tube it is hardly noticeable. Often it is hardly recognizable whether it is an e-bike at all.
The semi-integrated battery fits perfectly into the e-bike - the stability of the frame remains unaffected. The difference here is that the frame has to be designed somewhat wider.
The luggage rack battery is the simplest way to integrate a battery on the e-bike. The frame design is not influenced by the battery. Down tubes remain more filigree, and for deep climbers the access remains free.
The battery - the stronger the better?
Here you have to differentiate which type of bike you belong to and what your own e-bike should be used for.
On e-bikes, for example, the motor only helps when accelerating and on inclines. Because the motor is therefore only used occasionally, the power of 250 Wh is completely sufficient. The situation is completely different with e-bikes, whose batteries are constantly in demand, such as e-mountain bikes.
The watt-hours are quickly reduced when a few metres of altitude are accumulated, as well as when riding over ramps and through rough terrain. Up to 750 Wh is not too much in this case.
The range as well as sustainability and recyclability will determine the further development of the batteries in the future. With the constantly growing demand, we can be sure that we will be pleased to see more and more possibilities and refinements.
Memory effect with rechargeable batteries
If it behaves in such a way that only partial discharges take place over a longer period of time, the battery remembers this behaviour and then only provides the amount of energy previously required - the capacity has thus been reduced overall. Deep inside the battery, this process refers to a reduced voltage of the battery cells, some of which become unusable as a result.
You can prevent this disadvantageous chemical process if you follow our charging recommendations. However, if it has already happened, we recommend that you charge the battery completely in up to five cycles and then discharge it again strongly - with this tip you can reverse the memory effect that may already have occurred. However, if this does not work, we recommend changing the battery.
