Iridium Extreme - Battery Installation and Removal

Your Iridium Extreme® uses a rechargeable lithium-ion battery that locks securely into the back of the phone. This guide shows how to correctly install and remove the battery to ensure reliable performance and prevent power interruptions.

Tip: Before installing the battery for the first time, make sure it’s fully charged using the supplied AC or DC charger.

How to Install the Battery

1. Unlock the battery compartment

   • On the back of the phone, lift the D-ring latch and rotate it 90° counterclockwise to unlock the battery compartment.

2. Insert the battery

   • Hold the D-ring upright.

   • Align the bottom pegs of the battery with the slots inside the compartment.

   • Slide the bottom edge of the battery in first.

3. Secure the battery

   • Press the top of the battery down so it sits flush with the phone housing.

4. Lock the battery

   • Rotate the D-ring 90° clockwise to lock the compartment.

   • Fold the D-ring flat into its stowed position.

Note: Ensure the battery is fully seated and the latch is secure. If the D-ring isn’t locked properly, the phone may lose power or shut down unexpectedly.

How to Remove the Battery

1. Unlock the latch

   • Lift the D-ring on the back of the phone and rotate it 90° counterclockwise to unlock.
