The battery life should be clearly stated on the EPIRB. This life will be applicable regardless of storage or installation.

Yes it might still be uselfull after battery expiry date but in terms of meeting any local requirements, no, like here in West Oz where they are required to be carried (not a plb incidentally) ol'will
