Beacon Battery Warning

Cospas-Sarsat type approval is conducted with manufacturer installed battery packs in a beacon. Therefore, NOAA recommends that beacon owners always use manufacturer approved battery packs which have been tested as a part of the original Cospas-Sarsat beacon approval and known to meet operational requirements.  Beacon owners should consult their beacon manufacturer or one of their approved service centers to obtain proper battery replacements.  Certain aftermarket replacement battery packs that are not approved by the beacon manufacturer have been shown to be of inferior quality and may pose a safety risk and/or the failure of the beacon to function properly in a distress situation.
