How to Use

1. Ensure your Milwaukee M18 tool is powered off before inserting or removing the battery.
2. Align the battery pack with the tool’s battery slot and slide it in firmly until it clicks into place.
3. Power on the tool and verify normal operation.
4. Charge using a Milwaukee M18 compatible charger (e.g., M12-18C, M18C, or equivalent). The built-in BMS will manage charge termination automatically.
5. For long-term storage, charge to ~50% and store in a cool, dry place (15–25°C).
