I had the same model like yours. The battery died (did not hold charge) after 15 months. Hope you can do a video of how to replace the the battery or how to remove the battery from the circuit board. Many thanks.
Hmm, the battery should have a lifetime of more than 15 months unless it was a manufacturing defect. It is possible though that it is bad. Out of curiosity, once you have left the thermostat plugged into the USB for 5 hrs or so (until it is fully charged). How long does it last. If it immediately shuts off then it probably does have something to do with the battery or internal issues to the thermostat. If it lasts for more than 12 hrs, the issue is probably with your heating or cooling system.
@@lsm13b66 Thank you for your speedy reply. I charged it with USB for half a day. While charging, the unit was very hot to the touch (very unusual). When I put the unit back to the housing, it shows low battery and less than a minute, it shuts down. So I waited for a day and charged it for at least 7 hours. Then I put it back to the housing, the unit did not have any display. So my conclusion is the battery is defective. That is why I would like to find a replacement battery. I tried Amazon and does not find a good match. BTW, I do have 24V (C) connection to the furnace.
@@lsm13b66 If my heating system is over the voltage limit, would the Nest unit alert me about this when installing? (i.e. 120 volts is too much) I installed the Nest E, and the technical Power specs screen reads 30 volts when inactive, and 7 volts when the heat kicks on. All normal, right?
@@lsm13b66 That's scary. Since my oil burning system is just 4 years old, the guy at Ace Hardware said it likely was not high voltage, even though my old thermostat says 120. Good thing he was right!
@@lsm13b66 Thanks again for the video and the knowledge. I installed 2 Nests and it's cool to be monitoring my heat's performance. Hopefully can save a few dollars - have a warm winter!
Hi, Im looking at installing the Nest E on my parents old 2 wire mercury thermostat, when i tested the wires with a multimeter it showed 26v. Im sure that the Nest E will work on it and it should charge itself when idle since theres 26v when i tested the bare wires. im a little worried about the pulsing issue that some people have when the Nest is drawing power. Since our 2 wire constant systems work on a basic ON or OFF function, that shouldnt be an issue?? Im probably going to go ahead and give it a try tomorrow but if you know anything else that might help, i'd appreciate any advice you have to offer.
Great video. Just did my battery. How did you re-attach that ribbon connector? the little flap on mine will not "click" back down, latching the ribbon. Thanks.
i just installed the nest thermostat three days ago without a C wire. I have a red, white, yellow and white wire and nest told me that I do not need a C wire. It is turning on the heat, AC and fan perfectly. Do you think I should be worried about getting the C wire installed as it has been only three days. After watching your video I checked the furnance and I see six wires instead of 4 on the thermostat. I see one additional red and white wires. The additional white wire is connected to C and red wire connected to Y along with the yellow cable. Do you think I need to do anything?
Hassan Aslam, not if it’s working, I live in Florida so I’m not too familiar with heating systems but it’s possible that the additional c wire is tucked away behind the wall because the last installer didn’t need it. The only thing is that after 5 years or more the battery will start to degrade inside the nest thermostat and it might not be able to store or supply enough power to operate properly in which case a c wire would solve the problem. They haven’t been out for long enough though to tell and who knows, there’s lots of things that could happen in that time frame, maybe there will be something better by the time it becomes an issue. Thanks for watching!
Nice video. A customer of mine disassembled their Thermostat E looking for batteries. The thermostat is re-assembled but is getting the same error that you mentioned you had, saying to attach to base even though it already is. What exactly did you do to resolve it? I cannot see any connector that is not connected, but I must be missing something. Thanks!
Very nice video and helpful for me to tear down my nest thermostat. Thanks. Just let you know pronounce “China” as “Chi-Na” is considered discrimination (9:50 ). Just like “negro” for Black people.

@@fredchiu I agree with your diagnosis! I'll look
@@lsm13b66 Looking forward to view your next video. Thanks.
@@fredchiu I contacted support and am hoping they will help since google owns nest and youtube. twitter.com/googlenesthelp/status/1158147780210130946
This video is fantastic. Great explanation!
Peter Semetis Thanks man!

Peter Semetis yes, my guess is it would just short out and destroy the unit if the voltage was above 40vac.

those the same battery as a learning thermostat?

amazon replacement batteries are about 380mAh

I am having this same problem as well.
I’m in the same boat. Has anyone figured out a resolution yet?
Check the ribbon cable, maybe clean it with a pencil eraser.

I would desolder the microphone of that thing 😰
what KRAP design...you have to take the whole damned thing apart to replace a freakin battery...INSANE.
Don t buy Nest E thermostat they sre good for couple years then keep loosing the wifi i give 0 vote
