Raymarine Wind Transmitter Battery Pack & Seal Kit

The Raymarine Wind Transmitter Battery Pack & Seal Kit (TA125) is an essential maintenance component for anyone relying on accurate wind data at the helm. If you've spent years reading conditions across open water, you know that a failing wind transmitter battery can blind you to critical information when you need it most. This kit provides the replacement power source and protective sealing materials your Raymarine wind transmitter needs to maintain consistent, reliable performance through salt spray, UV exposure, and the constant thermal cycling that marine electronics endure.

Wind transmitters operate continuously at the masthead, converting real-time wind speed and direction into digital signals sent to your chart plotter and sailing instruments. The battery pack supplies the power that keeps this sensor active in all conditions, while the seal kit's gaskets and protective components prevent moisture infiltration—the primary failure mode for exposed marine electronics. Properly sealed transmitters resist corrosion far longer, ensuring your wind data remains accurate whether you're racing, cruising, or navigating in heavy weather. The compact 4 x 2 x 5-inch package is designed to fit within the standard transmitter housing, making replacement straightforward for experienced boaters and technicians.

This battery pack and seal kit is compatible with Raymarine's TA125 wind transmitter systems commonly found on sailboats, cruising vessels, and performance craft using Raymarine's integrated navigation and sailing systems. Anglers and boaters who monitor wind for casting accuracy, drift control, and weather prediction will appreciate the cost savings of refreshing the battery and seals rather than replacing the entire transmitter assembly. Installation requires basic tools and minimal downtime—typically a 20-minute job once you've lowered the mast or accessed your spar-mounted transmitter. For anyone invested in keeping their Raymarine electronics functioning at peak reliability, this replacement kit represents solid preventive maintenance.
