Bosch Battery Capacity Degradation

Robot vacuum runs for only a short time (e.g., 10–15 minutes) before returning to dock or shutting off, with no error code.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Aged lithium‑ion battery pack, Frequent partial charges, High‑temperature storage, Internal cell imbalance

Safety first: Do not open the battery pack casing.

1. Full charge: Place the robot on the dock and allow it to charge uninterrupted for at least 4–5 hours.
2. Full discharge test: Run a complete cleaning cycle and note the runtime. Repeat once more to recalibrate the battery gauge.
3. Check environment: Use the robot in a moderate temperature room (15–30°C) to avoid thermal limiting.
4. If runtime remains very short: The battery pack is likely worn and should be replaced with a genuine Bosch battery by a qualified technician.
