Nest Thermostat Not Charging or Low Battery – Quick Fix
Is your Google Nest Thermostat stopped charging or it frequently shows low battery notification? This article will show you how to fix the nest thermostat not charging issue or low battery issue.
Nest Wireless devices are very popularly used nowadays. And They enable remote and automatic control of devices such as heating and cooling systems. The Nest Thermostat runs on batteries that are recharged by the base unit to which it is attached.
This eliminates the requirement for manual battery recharge. When things go bad, the Nest thermostat displays a low battery alert. But you can fix it using the methods discussed below.
Reasons of Low Battery on Nest
Your Nest Thermometer may display a low battery alert for a variety of reasons. However, in the end, they all point to a single source of origin. The battery in your thermostat is not being recharged by the base unit.
For the battery to be recharged, the Nest thermostat requires a little charging current from your HVAC unit. In some cases, this may not be sufficient to maintain the battery charged to its maximum capacity.
Troubleshooting Nest to Fix the Battery Issues
Let me list down the troubleshooting methods below that you can use to directly reach the conclusion that is causing the Nest to show issues on your application and the devices related to the low battery or not charging properly.
Method 1: Nest Services
Make sure that Nest Services are online currently. There may be some days that Nest services are not working because of the outage of their server. And the issues you can face are created by Nest and you are not required to do anything but to wait for Nest developers to fix it.
But if your Nest Server is up and running, then you might troubleshoot the device using other methods listed below.
Method 2: Restart Your Nest Device
The first thing to do is to turn the thermostat off and then back on again. For this, press the thermostat ring, then go to Settings > Reset > Restart > OK on the Nest.
While the Nest device is being restarted you should also make sure that your Internet services are working properly and to be on the safer side you should restart your WiFi router as well.
These fresh starts can be used to change the settings on your thermostat and network, allowing them to “speak” to one another once more. Sign onto Nest Home and look beneath the photo of your thermostat to check if it says “Online.” If it does, it was successful. If this is the case, the problem has been resolved.
If it displays “Offline” even after restarting the Nest and the Router then we’ll need to keep troubleshooting until the problem is resolved.
Method 3: Verify the Batteries on The Nest
Make sure that the batteries on your Nest Devices are working properly and are not dead. To connect to your Wi-Fi network, the Nest must have a battery level of 3.6V or less. Go to Settings > Technical Info > Power on the Nest thermostat.
You should see the battery voltage as the first number. If you can see a battery voltage of around 3.6V then it is fine.
If the voltage is low, there may be a problem with the wiring and your Nest may not be charging. To test whether it makes a difference, try unplugging it and then replugging it. Call in a professional to inspect your wiring, if necessary.
Method 4: Perform Complete Reset on The Nest Thermostat
The last option you have if your batteries are working is to set the device to reset. To reset your router below is a step-by-step guide. Go to Settings > Reset > Network > Reset > Confirm to restart your Nest. Now, go to Settings > Network and follow the onscreen instructions to re-establish your thermostat’s Wi-Fi connection.
How Internal battery of Nest Thermostat is Charged?
An external USB connector on the rear of Nest Thermostats can be used to recharge their internal batteries. To begin, remove the thermostat’s display and connect it to your computer’s USB port or any other power source, just as you would normally charge your phone or another device. A red flashing light will appear on the item when it is charging.
Nest Low Battery How Long To Charge?
Nest thermostat if drained completely then it might take somewhere around 2hours or a little more to charge completely. And if the thermostat battery is not drained a lot then it should not take more than an hour to recharge.
How long does the Nest Thermostat’s battery last?
The thermostat uses the voltage in the cables to charge the battery, as previously stated. When the power goes off, it can stay working for 60 to 120 minutes at the most. Take note of the fact that if the thermostat is running low on power, the display will be turned off and wi-fi connections will be disconnected to save battery for a little longer.
This means that the thermostat has become “stupid” because it can no longer be controlled remotely, and most people agree. In any event, the Nest thermostat should resume its “smart” functions after a full battery recharge.
