Comprehensive Care Guide for NiMH Battery Packs in Radar Speed Signs

Overview

NiMH battery packs are crucial for the optimal operation of Radar Speed Signs. Proper handling, charging, and storage can significantly extend their lifespan and maintain their performance. Follow these recommended practices to ensure your Radar Speed Signs and their battery packs deliver safe, reliable service.

Radar Speed Sign and Battery Storage Recommendations

• Clean and Dry Storage: Keep the Radar Speed Sign and its battery pack clean and dry.

• Temperature Conditions: Store in a temperature range between -20°C and +35°C.

• Charging Before Storage:

• Charge the battery for approximately 10 hours before storage.

• Disconnect the charger and store the sign.

• Long-Term Storage Solutions:

• For storage extending beyond 30 days, use the supplied charger connected to a 24-Hour Mechanical Timer (e.g., Coleman Cables LLC #50001 or equivalent).

• Set the timer to be ON for 2 hours and OFF for 22 hours to prevent overcharging and maintain battery health.

Charging Method and Considerations

• Prevent Self-Discharge:

• NiMH batteries naturally discharge over time. Charge the battery for at least 10 hours prior to deployment to ensure maximum performance.

• Charging Connection:

• Ensure the battery is connected to the Radar Speed Sign via the field service panel (purple wire).

• Plug the charger into the battery charger socket on the back of the sign to ensure a proper charge.

Long-Term Handling and Maintenance

• Avoid Prolonged Storage with Load:

• Do not store the battery connected to a load for extended periods as it can lead to reduced charge capacity.

• Recovering Battery Capacity:

• If the battery shows reduced capacity after extended storage, it can generally recover after two or three charge/discharge cycles.

Conclusion

By adhering to these storage, charging, and handling guidelines, you can maximize the performance and lifespan of your NiMH battery packs in Radar Speed Signs. Regular maintenance and proper care are essential for ensuring that your signs continue to operate efficiently and effectively over their lifetime.
