Raymarine 3-Up Replacement Battery Pack and Seal Kit, For T121, T122, T112

Overview

The Raymarine TA119 is a 3-up replacement battery pack and seal kit for servicing compatible Raymarine wireless instrument components. It is used when the internal battery pack needs replacement and the cover seal should be renewed at the same time, helping the instrument go back together correctly after service.

This kit is especially relevant on sailing boats using Raymarine wireless instrument hardware, including the Hull Transmitter and T122 Wireless NMEA Interface. It is also used in Raymarine Maxis installations that require two TA119 battery packs. The package is small and light, with box dimensions of 2 inches high by 4 inches wide by 5 inches long and a listed weight of 0.15 lb.

Key features

• 3-up replacement battery pack for compatible Raymarine wireless instrument components.
• Seal kit included so the unit can be reassembled with a fresh seal after the battery change.
• Applicable to Raymarine Hull Transmitter and T122 Wireless NMEA Interface service work.
• Also used in Raymarine Maxis installations where two TA119 battery packs are required.
• Compact spare part that is easy to keep aboard for planned maintenance during a refit or instrument service.

Compatibility and fit

This kit is intended for specific Raymarine wireless instrument hardware, not as a general battery pack for unrelated onboard electronics. Before ordering, match the instrument model and service requirement to the unit being opened, especially on older Tacktick or Raymarine wireless displays and transmitters.

Very early white Tacktick instruments without a rear battery cover are a special case and may not be serviceable in the same way. For wind transducers and remote controls, use the correct Raymarine battery pack for that product rather than assuming this kit fits every wireless instrument in the system.

Installation and service notes

Battery replacement requires opening the instrument or interface housing, removing the old pack, fitting the replacement pack, and resealing the cover. Work in a dry, clean area so the seal area does not pick up salt, dust, or grit during reassembly.

On boats that see spray, washdowns, and regular deck moisture, the seal is just as important as the battery pack. Take time to seat the seal correctly before closing the housing, and check the unit carefully before returning it to service.

Use cases on board

This is a practical maintenance part for sailboats that rely on wireless wind, speed, depth, or NMEA interface data during coastal cruising, club racing, or longer passages. It is a good match for owners and marine technicians refreshing aging Raymarine wireless instrument components rather than replacing the full instrument system.
