What is a cycle type as opposed to a standard type?
Cycle types are very important for many rehab applications. These batteries are designed for constant charging and discharging. This is the case with a scooter or electric wheelchair, for example. The battery is discharged during the day and usually only reconnected to the charger at night. The term cycle stability indicates how resistant a battery is to this cyclical load. A cycle type can therefore withstand considerably more charging and discharging processes than a standard type. The main design difference between a cycle type and a standard type is the lead plate thickness of the battery. Thicker lead plates are installed in the cycle type. For this reason, cycle types are generally heavier and therefore more expensive than standard types.
Which batteries can I install for which wheelchair?
Battery manufacturers don't make it easy for our customers. Our rehab advice experts already know which battery is suitable for many wheelchair models and can provide you with expert advice. Together we will find the right product for you. Capacity (Ah), dimensions and area of application are the decisive parameters for selecting the right battery.
Why do DC-AGM and gel batteries generally make more sense than lithium batteries in wheelchairs / scooters?
Lithium-ion batteries have both advantages and disadvantages, which should be carefully considered, especially in the rehabilitation sector. For example, lithium batteries are very light. Heavy lead batteries are usually required as a counterweight in the wheelchair to maintain tipping stability. The BMS (battery management system) of the lithium batteries could abruptly block the wheelchair from continuing its journey at high discharge depths, e.g. at danger points such as traffic lights. Choosing the right charger is also important. If you are interested in lithium batteries, it is therefore essential that you speak to our rehab advice team.
Which charger should I use?
Caution with the various types of batteries! There is different charging technology for acid, gel, AGM and lithium batteries. An incorrect charger can damage the battery and, in the worst case, lead to an explosion. Always seek advice. Please do not experiment!
Do I lose my warranty claims if I do not buy the batteries from the wheelchair manufacturer?
No, the warranty claims do not expire if you buy replacement batteries from us.
Do replacement batteries have the same service life / quality?
Yes, the replacement battery may even be better. What is important is the production date of the battery, the correct internal structure and the weight. In wheelchairs, the original batteries are often installed ex works and can therefore be several months old when purchased in Germany. Depending on the technology (DC-AGM, gel or acid), there are differences in durability. It can also be said that the heavier a battery is, the longer the expected service life.
How do I charge rechargeable batteries correctly to maximise their service life?
Avoid partial charging of DC AGM and gel batteries at all costs (e.g. only charge in the afternoon). As a rule, charge for approx. 12-14 hours after each use. If possible, charge your battery at least 24 hours before using it for the first time. The deeper you discharge a battery, the shorter the expected service life will be. A deep discharge is particularly damaging to your battery.
