(The service life may be shorter, depending on the conditions of use.) When the battery becomes weak, the range of the card remote commander becomes shorter. Replace the battery with a new CR2025 lithium battery. Use of any other battery may present a risk of fire or explosion. + side up 2c 1 Notes on the lithium battery • Keep the lithium battery out of the reach of children.
