Our services
Repair instead of buying new.
In a battery, it is primarily the cells that age. We replace them with new ones - this is often an economical and resource-saving alternative to buying new ones.
Testing & advice
Is the battery no longer charging or does it switch off too early? We'll check it and tell you whether it's worth repairing.
More capacity
If desired, we can use cells with higher capacity – in the same housing, provided the electronics and charger allow this.
Calculate upgrade →Existing housing
We replace the cells inside the existing battery pack. We currently do not offer newly built custom battery packs.
Many cell formats
We re-equip existing battery packs with nickel or lithium-ion cells. The appropriate format depends on your battery.
