Setup Instructions
Follow these steps to set up your UpBright AC/DC Adapter for charging your Hyper Tough 12V Max tools:
- Verify Compatibility: Ensure your Hyper Tough tool's battery is a 12V Max 1.5Ah Li-ion type. This adapter is specifically designed for models such as 99303, 99307, 93307, 99312, 98936, and 99334.
- Connect the Adapter: Insert the barrel connector of the UpBright adapter into the charging port of your Hyper Tough battery or tool's charging base.
- Plug into Power: Plug the AC end of the adapter into a standard 100-240VAC 50/60Hz wall outlet.
- Begin Charging: The battery should begin charging automatically. Refer to your tool's manual for specific charging indicators.

Operating Instructions
Once the adapter is properly connected to your battery and a power source, the charging process will commence. The adapter is designed for continuous use during charging cycles. Always ensure the adapter is placed in a well-ventilated area during operation to prevent overheating.
- Charging Time: Refer to your Hyper Tough tool's battery manual for estimated charging times.
- Disconnection: Once charging is complete, disconnect the adapter from the power outlet first, then from the battery/tool.
- Safety: Do not use the adapter if the cable is damaged or if the adapter casing is compromised.
Care and Maintenance
To ensure the longevity and optimal performance of your UpBright AC/DC Adapter, follow these maintenance guidelines:
- Cleaning: Wipe the adapter with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Storage: Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Cable Care: Avoid bending or crimping the power cord excessively. Do not place heavy objects on the cord.
- Inspection: Periodically inspect the adapter and cable for any signs of damage. Discontinue use if damage is observed.
Troubleshooting
If you encounter issues with your UpBright AC/DC Adapter, consider the following:
- Adapter Not Charging:
- Ensure the adapter is securely plugged into both the wall outlet and the battery/tool.
- Check if the wall outlet is functional by plugging in another device.
- Battery Condition: Rechargeable batteries have a limited lifespan, typically 1 to 3 years. An old or faulty battery may not accept a charge, which is not an issue with the charger itself. Consider testing with a different battery if available.
- Overheating: If the adapter feels excessively hot, disconnect it immediately. Ensure it is used in a well-ventilated area and not covered.
- No Power Indicator: If your tool or battery has a charging indicator and it's not lighting up, recheck all connections.
