Battery maintenance

The EPIRB is powered by a replaceable battery pack (Orolia Ltd Part No. 23-
270). This is a non-rechargeable sealed unit containing three 3V battery packs
with each pack containing two 1.5V lithium iron disulphide cells.
The battery pack needs to be replaced every 10 years or by its expiry date. If
the EPIRB is covered by SOLAS regulations, then it will need to be changed
every 5 years or as required by any local or ship registration requirements (see
schedule on page 24).
The battery pack expiry date is marked on the battery pack cover (under the
lanyard) and, if you have a float-free enclosure, it is also marked on the base
of the enclosure cover. The battery expiry date should be checked regularly.
You should also replace the battery:

If the EPIRB has been used in an emergency situation, or

When a false activation has occurred and a self-test indicates that less
than 48 hours operating time remains. It is recommended to replace the
battery after any false activation.
Lithium batteries have special disposal requirements. Never incinerate a
lithium battery. Never dispose of one at sea. Your Approved Service Agent will
be able to deal with battery disposal.
NOTE – Regardless of the battery state, the EPIRB should always be
activated in an emergency – it may still be capable of generating an alert.
