5. Setup and Installation
Before installing the new battery, carefully review the following instructions:
- Verify Connector Specifications and Polarity: Compare the connector of your new battery with the original battery. Ensure the red wire connects to the positive ("+") terminal and the black wire connects to the negative ("-") terminal. Incorrect polarity can damage the device and battery.
- Addressing Mismatched Connectors: If the primary battery of your device has no plug, a mismatched plug, or mismatched polarity, you have two options:
- Cut and Solder: Carefully cut the plug from the original battery and solder it directly to the new battery's wires, matching the color (red to red, black to black).
- Use Heat Shrinkable Insulating Sleeve: If soldering is not feasible or preferred, you can cut the wires and use the provided heat shrinkable insulating sleeve to connect the same color wires securely. Ensure connections are insulated properly to prevent short circuits.
- Secure Installation: Once connected, ensure the battery is placed securely within the device, avoiding any pressure on the wires or battery itself that could cause damage.

6. Operating Guidelines
Once installed, the HXJNLDC 802540 battery operates like the original battery in your Sena headset. Ensure your device is fully charged before initial use.
- Charging: Use the original charger and charging cable provided with your Sena headset. The battery is designed with protection against overcharge, overdischarge, overcurrent, and short circuits.
- Usage: The battery provides a capacity of 900mAh, offering reliable power for your compatible Sena headset. Actual operating time may vary based on device usage patterns (e.g., continuous music playback, intercom use).
