Bosch batteries are among the most reliable systems on the market. Nevertheless, after a few years, their capacity declines or the electronics report errors. At our workshop in Rapperswil, we offer a specialized Bosch battery repair service that goes far beyond simple cell replacement.
We replace worn-out cells with new high-performance components. This allows us to turn a weak battery back into a powerful companion with full range.
Using PC-based diagnostic tools, we read your battery’s error memory, perform software updates, and create a detailed report on the condition of the cells.
Whether it’s a defective charging socket, damage to the housing, or problems with the battery management system (BMS) – we check which components can be repaired to avoid an expensive new purchase.
If your Bosch battery no longer charges, we use special charging methods to safely reactivate deeply discharged cells.

Since batteries are considered hazardous goods, you have two options:
In person: Bring your battery (and charger!) directly to us in Rapperswil. This is the safest option and does not cost you any postage.
Shipping: Swiss Post does not transport used lithium batteries. Please use a private logistics service provider and pack the battery well-padded in a sturdy cardboard box.
Our specialists will thoroughly examine your battery.
Only after the diagnosis do we decide together which repair (e.g., cell replacement or electronics check) really makes sense.
Once everything has been checked and tested, you can pick up your battery from us again or we can arrange for it to be returned to you by a specialist shipping company.
Register your Bosch battery now – we will get back to you quickly to discuss how to proceed.
