Raymarine Wind Transmitter Battery Pack & Seal Kit

Overview

The Raymarine TA125 is a replacement wind transmitter battery pack and seal kit for servicing Raymarine wireless wind instruments, including the T120 wireless wind transmitter. It is used when the transmitter’s internal battery pack needs replacement and the housing seals should be renewed during reassembly.

This is a small maintenance part, but it matters on a sailboat because the wind transmitter works in one of the harshest places on board: high on the mast, exposed to sun, rain, salt spray, vibration, and temperature changes. Replacing the battery pack and seal together helps keep the transmitter powered and properly closed after service.

The kit does not change the vessel’s 12V or 24V electrical system and does not add wiring to the boat. It services the wireless masthead transmitter itself, so fit should be confirmed against the Raymarine wireless wind transmitter model before purchase.

Key features

• Replacement battery pack and seal kit for Raymarine wireless wind transmitters.
• Compatible with the Raymarine T120 wireless wind transmitter.
• Useful for restoring the transmitter’s internal stored power when the original battery pack has reached the end of its service life.
• Includes sealing components for closing the transmitter housing after battery replacement.
• Supports continued use of an existing wireless wind setup without replacing the full masthead transmitter.
• No vessel power rewiring is required because the service is performed inside the wireless transmitter.

Installation and setup

Battery replacement requires opening the wind transmitter, fitting the new battery pack, and resealing the housing carefully. The work calls for steady handling because the transmitter must be reassembled in a watertight manner before it goes back into masthead service.

Before installation, remove power from related instruments where applicable, work in a clean area, and keep the old seals away from the reassembled unit. After service, check that the transmitter communicates normally with the onboard wireless instrument system before going offshore or relying on wind data for sail trim.

Compatibility and fit

This kit is for Raymarine wireless wind transmitter service, with confirmed use on the T120 wireless wind transmitter. It is not a universal O-ring assortment or a general electronics battery kit, so it should be matched to the transmitter model rather than selected by size alone.

It is a practical replacement part for owners maintaining Micronet-era Raymarine wireless wind systems on cruising sailboats, club racers, and other boats where keeping the existing masthead sensor in service is preferred over replacing the full wind package.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
