⚠️ Known Issues
- This adapter is compatible with all battery capacities (Ah). However, weak or low-capacity batteries below ~3Ah may experience reduced performance or unstable operation.
-
Due to the built-in delayed output protection, some Kobalt 24V angle grinders may require a short restart sequence.
Turn the tool switch on briefly, wait approximately 3 seconds, then turn the switch on again for normal operation.
Most drill-style tools do not require this additional step.
