AcuRite Iris® (5-in-1) Draining Batteries


If your AcuRite Iris® (5-in-1) sensor is losing connection to the display unit and/or AcuRite Access®, the low battery icon is often present on the display, or the sensor is going through batteries too quickly, please review the troubleshooting suggestions below. We expect recommended batteries to last between 12-24 months. If your batteries are not lasting at least one year, we would recommend the following troubleshooting steps.


You would want to ensure the following first:

  • Verify you are using fresh batteries in the sensor. Lithium batteries are recommended for installation locations where temperatures can go below -4°F/-20°C.
  • Verify you are using batteries with a nominal voltage of 1.5 volts.          
    NOTE: Some rechargeable batteries carry low or inconsistent voltages that may not properly power the device.  
  • Mixing different battery types (brands, old/new, etc.) is not recommended.


Once you have verified that you are using recommended batteries, please perform one of the following resets:

Please follow the steps carefully as the order is crucial to the success of the reset.

If a hard reset does not correct the issue, (Ex. the batteries drain within a few weeks or months, the sensor still loses connection with the display and/or AcuRite Access®, or the low battery icon reappears) please use the following link to verify if your outdoor sensor is compatible with a replacement part that we offer.

Is My AcuRite Iris® (5-in-1) Compatible with the Replacement Temperature and Humidity Board?


If your outdoor sensor is considered "compatible", please proceed with the steps below:

To help us analyze what may be causing the issue you described and the next steps needed, you will need to get the OUTDOOR sensor:

  1. Please remove the 4 screws holding the sensor together and separate the 2 halves.
  2. Once separated, in the bottom half, locate the black/red wires that are connected to a skinny green or black board-this is the temperature and humidity board.
  3. Remove this board from the slot and inspect the part for signs of damage or corrosion. You may see a green or white buildup or some discoloration of the components.
  4. Please also remove the black cover and inspect the main circuit board for any signs of damage or corrosion.
  5. You do not need to remove the screws that are holding the mainboard into the sensor.
