The GS-46 battery pack uses lithium manganese dioxide chemistry to provide the 5 watts

of power mandated for 406 ELTs. It has a replacement life of 5 years. The individual battery

cells are encapsulated in a wide temperature range silicone potting material. Our process

ensures structural integrity, waterproofness, and protects the cells from

environmental hazards.

The GS-46 battery pack can be easily installed in the field by opening the cover of the ELT, removing the old battery and connecting the new battery. Because of the lithium content these batteries are shipped as HAZMAT and must be discarded as HAZMAT.

These battery packs are approved under TSO-C126 and TSO-142.
