Can I have my battery tested for its current condition?
Yes, but this requires laboratory measuring equipment.
How long do I have a warranty on batteries and rechargeable batteries?
The warranty period for batteries and rechargeable batteries is 6 months.
When should batteries be replaced?
When the battery pack for the actual application (e.g. e-bike, golf trolley) can no longer provide sufficient energy to ensure proper operation.
However, one should always remember the environmental apse. Disposal of batteries is relatively costly for the sake of the environment.
Everyone should therefore consider before disposal whether it is really necessary.
There are in addition, other reasons, which should lead to a direct however appropriate disposal.
It can be dangerous if the battery has been mechanically damaged, e.g. if it has been dropped.
Even if the battery should become noticeably warm during operation, it is advisable to have it checked. You can have this done by a company specialized in batteries.
With lithium-polymer batteries it can also happen that they become inflated. Cells in this state are often subject to very high pressure, which can be very dangerous.
These batteries should also be disposed of properly as soon as possible.
Where can I dispose of batteries and accumulators?
It is best to dispose of your rechargeable batteries at your specialist dealer or at the appropriate collection points for problematic materials.
If it concerns single cells that you would like to dispose of, there are already many markets nowadays that offer battery collection boxes for disposal.
In order to prevent batteries that accumulate in such boxes from developing a danger of short circuits, it is always better to tape the poles against them.
What is a charge cycle?
A charge cycle describes the charging of a battery from the lowest state of charge up to 100%.
What is rated voltage?
The voltage of an electrical device or voltage circuit in normal operation. This value is usually specified by the manufacturer, a lithium ion cell for example has a nominal voltage of about 3.6Volt. The nominal voltage of a battery can be found in the technical data sheet.
What is operating voltage?
The voltage required to operate an electrical circuit and thus a device.
Can I still buy NiCd (Nickel-Cadmium) rechargeable batteries?
Since 2017, NiCd batteries may only be used in emergency systems, emergency lighting and medical equipment. Only stocks already in the EU may be sold. NiCd batteries can be replaced by NiMh (nickel metal hydride) batteries of the same construction and the same values. Old chargers can still be used for NiMh batteries.
What controls the protection electronics (pcb)?
In general, everyone should make sure that their battery is not operated improperly or exposed to unfavorable or even dangerous conditions.
How to handle the battery correctly is described in detail in the enclosed information sheet or you can find the necessary information on the homepage.
If an unfavorable situation should occur for the battery nevertheless, the protective electronics will ensure that the battery will interrupt operation and thus avoid a potentially dangerous situation. These include circumstances like:
- Protection against overcharge
- Protection against discharge into the deep discharge area
- Protection against too high currents (e.g. in case of short circuit)
- Dispose of protection against too high temperatures.
What is deep discharge of a battery?
Deep discharge of a rechargeable battery is the state after current withdrawal until the capacity is almost completely exhausted or until it falls below a certain voltage.
What does self-discharge mean?
Self-discharge is the term used to describe processes that occur automatically and lead to batteries and accumulators discharging more or less quickly, even if no electrical consumer is connected.
Should I remove the battery from my device when not in use?
Yes, because even when the device is switched off, a small current could flow, which leads to a deep discharge after a long time.
What is the memory effect?
The memory effect: If NiCd batteries are not fully discharged before charging, this point becomes their full operating capacity. The battery "remembers" how far it has been discharged and can no longer be used afterwards. To a lesser extent, the same memory effect occurs with NiMH batteries. This is caused by a change in the crystals on the electrodes in the battery.
Can lithium-ion batteries explode?
Yes, they can. However, we are talking here more about inflammation than explosion, and for that to happen, a lot must have gone wrong when handling them.
In general, always make sure that a suitable charger is used, especially for Li-Ion batteries. This charger should also meet a certain quality standard, so please do not buy batteries and chargers from unknown sources. When buying your battery, ask if it is equipped with a protection electronics (usually also called PCM) with integrated balancing. These electronics monitor the battery and protect it from all inadmissible events. Should one of these events occur, the battery will switch off and go into self-protection, which you can reset yourself in most cases. If you follow these points, you will be safe with the Li-Ion technology and can use the enormous power of these batteries without any danger.
Can I charge my lithium-ion batteries with any charger?
No, only with a suitable lithium-ion charger.

Replacement batteries may only be stowed in hand luggage and must be packed individually and protected to prevent short circuits.
Only batteries for personal use may be carried.
Can I have an e-bike battery or lawnmower battery repaired or replaced?
