4. Endurance
The energy is provided by a battery pack composed of 3 LiMnO
2
D cells (See
pages 107 & 602 for Kit battery reference).
The endurance of the 121.5/243 MHz transmission is close to 100 hours at
-20°C with new batteries.
In the worse conditions possible, a distress is pinpointed 5.5 hours maximum
after the ELT activation and the position is subsequently updated (if necessary)
every 2 hours.
As it is therefore preferable to keep the battery power for 121.5/243 MHz
homing frequency transmission for the rescue operations, the 406 MHz
transmission is deliberately stopped after 24 hours to extend the 121.5/243
MHz transmission for as long as possible.
The transmitter battery expiry date is fixed at 7 years from date of cell
manufacturing (CDOM). If no activation of the ELT occurs during the battery
lifetime, it shall be replaced before or at battery expiry date
(see NOTE below)
.
NOTE: The expiry date takes into account FAR 91-207 (i.e. batteries to be
replaced when 50 percent of their useful life has expired).
Lithium cells, lithium batteries and equipment containing such
batteries are subjected to regulations and classified under class 9 as
from 1st of January 2003.
