Battery Pack
The power source for the Petrel is its battery pack. There are two battery pack sizes for the Petrel:
Long Pack
7 Energizer LR20 D-Cell Alkaline
10.5V
Short Pack
3 Saft LSH20 D-Cell Lithium
10.8V
For Lithium models, only the Saft LSH20 has the ability to source enough current to supply peaks
in Iridium transmissions.
Replacing Batteries
The mechanism for installing the batteries is the same regardless of which enclosure is provided.
A plastic insert is vacuum-sealed to the full length of the inside of the battery chamber to prevent
internal shorting.
To replace the batteries:
•
Tip the old batteries out of the enclosure once the end-cap has been unscrewed. Make
sure to dispose of them appropriately.
•
Slide the first battery into the column, ensuring that the positive (+) terminal faces the
head of the Petrel (or SubConn connector if a Remote Head).
•
Add the remaining batteries in the same orientation.
•
Restore the endcap to its place on the device, taking care to inspect the O-ring first.
Batteries should be removed if the device is entering storage.
