Remove failed battery

You must remove the failed battery so you can install the new one. Remove the battery by squeezing the tab and disconnecting the connector housing. Then, you can pull the battery out of the controller.

Procedure

  1. Remove the controller canister's cover by unscrewing the single thumbscrew and lifting the lid open.
  2. Confirm that the green LED inside the controller is off.
    If this green LED is on, the controller is still using battery power. You must wait for this LED to go off before removing any components.
  3. Locate the 'press' tab on the side of the controller.
  4. Unlatch the battery by pressing the tab and squeezing the battery casing.

  5. Gently squeeze the connector housing the battery wiring. Pull up, disconnecting the battery from the board.

  6. Lift the battery out of the controller and place on a flat, static-free surface.

  7. Follow the appropriate procedures for your location to recycle or dispose of the failed battery.
    Warning: To comply with International Air Transport Association (IATA) regulations, never ship a lithium battery by air unless it is installed within the controller shelf.
