Changing batteries is also done quickly and independently and does not take more than a few minutes. Below is a guide on how to replace the battery on a Vivint thermostat, Scroll down to get more details.

Materials Needed

  • New AA alkaline batteries are designed for high-drain purposes. These thermostats require two batteries for their operation. Other types of batteries that can be applied are lithium batteries.
  • Phillips head screwdriver
  • Before replacing the batteries, it is advisable to ensure the thermostat and the HVAC system are off.
  • Make sure that the new AA batteries are close at hand. Two batteries are required.
  • Ensure no furniture items or other objects block the thermostat to make accessing it easier.

Instructions Step 1: To proceed with the repair, the front housing must first be located and then removed.

  • The battery should be placed at the back of the thermostat housing. To get to it, one will have to take off the housing that is at the front side of the thermostat base.
  • It is to mention that there are no screws on the housing. Hold the two lower knobs on the housing with one hand and pull both firmly upwards and backward until it is completely removed from the base. The housing is attached using exceptionally robust integrated magnets.

Step 2 In this process, old batteries are removed or disconnected from the circuit.

  • With the housing stripped off of the thermostat, you will find the batteries located at the top of the base of the thermostat.
  • Take off the old batteries by pulling each one in the upward direction to avoid confusion. Batteries: Remember, the polarity and arrangement of each battery inserted. There are indication marks that show where the positive and negative terminals are located.

Step 3 As you reach this part, you will need to insert new batteries.

  • Closely, look at how the old AA batteries were placed in the battery compartments and replace each new AA battery in their respective positions with polarity marked.
  • Take the time to apply the right amount of pressure on the top of each battery to ensure proper contact as well as lock the connection.
  • Do not try to fit the batteries in them forcefully. If they are placed at the right angle, they should fit perfectly and they should not cause any disarrangement.

Step 4 Replace the Housing As discussed the current housing at the site

  • After putting in fresh batteries in both compartments, place the front housing piece back to the base of the thermostat.
  • Begin with the bottom edge and apply a slight amount of pressure in the direction of the base on the housing. The built-in magnets present at the rear end of the broken part will easily capture and fit the part back in its position.
  • There will be a clear sound indicating that the housing is connected back through the right sequence. Ensure that it has a proper standing and is in contact with the base perfectly.

Step 5 Reset power and test

  • For this, turn the thermostat power back on using a switch at the bottom edge of the base.
  • It should be noted that the home screen information can be viewed once the display screen is turned on.
  • Set the temperature to high, turn the mode to heat, and set the temperature again to test the operations of the thermostat with new batteries.

With the AA batteries replaced, the low battery sign is not supposed to appear on the display again. The batteries serve as a backup source for powering the smart thermostat and keeping it running in the case of a power failure. They will usually last about one to two years before they begin to wear out with normal use in most thermostats. Occasionally, ensure your Vivint thermostat is charged to avoid a situation where the battery power is drained while it is still in charge of regulating the heating and cooling system of your home. Sometimes, it can be caused by a faulty battery and since the batteries are easy to change, this is the first point of call if display or responsiveness issues are detected. It is crucial to service your Vivint smart thermostat accordingly and here is the battery replacement guide when necessary.
