How do I change the batteries of the LEUCHTIE Plus and Premium?

  • The battery life is approximately 100 hours.
  • Use branded AAA/Micro alkaline batteries (not rechargeable batteries) and remove dead batteries immediately to prevent damage from leaking batteries.
  • If the LEUCHTIE will not be used for an extended period, such as during the summer, remove both batteries.

Replace both batteries immediately if the brightness of the LEDs decreases significantly or if the LEUCHTIE turns off again shortly after being turned on.

Change the batteries in a dry and clean place. Make sure that both the LEUCHTIE and your hands are dry and free of grease.

Replacing the batteries:

  1. Detach the light tube from the battery compartment one side at a time. While doing so, hold the silicone sleeves on the battery compartment firmly.

  2. Remove the two used batteries.
  3. Insert 2 new batteries (alkaline AAA/Micro, not rechargeable) into the battery compartment so that
    the positive terminal is visible on one side
    and the negative terminal is visible on the other side. Here is how to insert the batteries into the LEUCHTIE.
    The sockets at the end of the light tube each contain a contact spring on both sides, as well as a red and a blue mark. Connect the light tube and the battery compartment as follows:
    • the end of the tube marked red to the positive terminal
    • the end of the tube marked blue to the negative terminal
    Press the battery compartment and the light tube firmly together as far as it can go - there should be no gap visible between the battery compartment and the tube.

    Here is how to close the LEUCHTIE after changing the batteries. The light tube must be securely connected to the battery unit.

Test that it works. If the LEUCHTIE isn't working, check the following:

  • Are both batteries inserted correctly?
  • Is the light tube attached to the battery compartment the right way around?
  • Is there a contact spring protruding from each end of the tube?
    The springs must not be kinked or bent. They must both be straight and screwed firmly into the nut.
