280mAh/3.7V Replacement Battery for Nest C1241290 Vido Doorbell Wired NC5100US Hello 1ICP7/17/26

This seems to have fixed my original Nest Hello(Pre-google buy out) that had after years of very reliable use started disconnecting and shutting down until it ultimately would only record a few seconds and then shutdown for hours again. As Clark Moore(above comment) said, you only need to get to step 4. No need to keep disassembling. The o-ring did not seem to require replacement, though I did apply some pure silicone grease to help it seal and hopefully make the inevitable next replacement easier. In the instruction it was not clear to me, but if you look closely at the pictures for step 4 there are 2 snap fitting on each end and on each side. This information may help in step 3. Mine was much harder to pry out than I had expected. Good luck, and thanks to those who provided info!

I can confirm. Replacing the battery fixed the issue with the Nest disconnecting when someone would ring the doorbell. The O-Ring was still good and when I put everything back together, I put a few dots of gorilla glue under the faceplate. Also, there is no need to remove the motherboard to replace the battery, you can remove it in Step 4. I also connected the nest to a USB charger overnight, in case the battery needed some power. Lastly, I also ordered a silicone cover for the Nest that really helps the aesthetics, since the faceplate was peeling and looking old. Good luck, it's a rather easy repair.

Steps 6, 7, 8 and 9 were totally unnecessary to remove the battery. You can see the battery in the picture in step 5, no need to keep disassembling. Also, you will need some adhesive to reassemble, otherwise the faceplate will just fall off. I used 3M General Purpose 45.

Great instructions, thank you! If you only want to exchange the battery, steps 4-9 are not necessary - the battery can be removed directly and exchanged after step 3. I used a NC5100US (280 mAh, 3.7 V) replacement from the world's biggest online retailer.

Can confirm that you only need to do Steps 1-4 to replace the battery.

Can confirm is Step 1 is a royal pain to do to. You have to slip the pick all the way under the face plate all the way around to separate the glue from the face plate. Don't try to pry the face plate off, or you might crack it. And once you do this, you'll have to re-glue it back on because there will be nothing holding the face plate to the doorbell.

I followed this guide and big thanks to those who shared the link to purchase a battery. Oddly it did not seem to work right away. I plugged the doorbell once assembled to charge for 15 minutes or so and then installed.

About 24 hours later it just started working again so it was definitely the battery. You will need to get some glue for the cover and do not try and scrape off the foam adhesive. I just used my fingers to pull away any clumps and applied about a q-tip amount of flex seal in certain spots and held together for five minutes .

Yeah because the comments are hidden under load more comments, I started doing steps 5-8 which was annoying, not just because of the extra needless steps, but because the 6 screws in step 6 are actual 3 and 3 of slightly different screws, so reassemble got confusing.

Also I did slice my cable to the case that it warns about, I thought I was done for, and was just continued the steps to complete incase I could get my hands on an old one for parts, but then when I reassemble I realized it was just the usb cable, which is not necessary the battery was charged already and now my Nest Hello works and no longer cuts out on button presses.

There were also two rubber bumpers inside the white case that fell out, I only noticed one falling out, so it took me a while to find where they went (button side of white case) I couldn't find the second bumper, but seems to work okay with out it.

well that didn't work. the faceplate snapped in half. I suspect that the old plastic having been in the sun for so many years didn't help. Oh well.

Ok, so I did the swap and no more blank video. But now I don't have sound.. I can barely hear anyone talking, and they cant hear me at all. Anyone else have this issue?

Absolutely the worst instructions ever. Doesn't matter, this thing isn't supposed to be serviced.

1. It's nearly impossible to remove the faceplate without breaking it.

2. Doesn't show which side the ribbon cable is on, important for opening!

3. Doesn't mention the copper item around the battery (strain gage for detecting puffing?) or its wiring. This is stuck onto the battery, and the replacement battery doesn't come with it. It will be destroyed if you try to peel it off the old battery. I have no idea if the unit will function with this bit disconnected/destroyed.

I just completed this, and my old battery was puffy, so it was ready to let out it's magic smoke. The doorbell gave no warning about the puffy battery, so I assume it wasn't a strain gauge. The new battery did come with copper around it, but the connector was coming out of the opposite end of the battery on the replacement, and the connector had to be rotated 180 to keep the color orientation as the original when I put the label in the opposite way from the original. I will say to be careful around the thin part around the doorbell and camera openings, as I broke the cover one time at each end while spudging when I should have been picking. Luckily, it was only one break per end. I ended up using a thin paring knife to cut through the foam, the picks didn't seem like the most efficient way of cutting the foam, but vital for making enough room to get the paring knife in.

Thanks so much for these instructions. Here is the battery I used, and it fixed the problem I was having with the door bell rebooting.

Nest Hello Doorbell (Wired, Gen 1) Replacement Battery: Battery Replacement for Nest Hello Vido Doorbell Wired NC5100US C1241290 1ICP7/17/26 (280mAh/3.7V)

Totally broke my Nest Hello trying to replace the battery following these instructions. The faceplate cracked when I was trying to pry it off, the O-ring tore as well, and the real kicker was ripping that ribbon cable when I finally got to the battery.

As others have said, it would be nice to point out where that ribbon cable is to prevent people from damaging it. It's on the right side of the unit near the top of the button.

Glad I gave this a shot, but be warned; it's extremely difficult to open this thing up. Also glad I can finally throw this piece of $@$* into the garbage now that it's fully broken.

This one should work: https://a.co/d/9tWcSkf

It is what I ordered.

The replacement batteries suggested/on Amazon are listed as 1|CP7/17/26 (280mAh/1.04Wh/3.7Vdc). However my 1st gen Nest Doorbell has a 1|CP7/17/26 (300mAh/1.14Wh/3.80Vdc). Will replacement be sufficient?

FYI, when facing the Nest hello, the ribbon cable is located near the bottom right side of the button (I may have missed this info in the above much appreciated instructions and everyone's input!). I needed to use a small thin flat blade metal screwdriver to ever so gently pry the faceplate off (and then internals out). As mentioned before, the back of the faceplate is attached to the internal component using a foam like adhesive so, as I would get the separation to occur in one side, I would then slide in a spudger and credit card to keep the separation open so I could then continue to gently slide it in and continue to open / remove the faceplate. I needed to also use the metal (more rigid) thin screwdriver between the component and white case to start the removal process, again going slow and being careful to not use too much pressure to crack the case. Also there is a blue silicone gasket just below the internal component face so again, go slow and a bit deeper to ensure you do not damage it.

I got a replacement battery from Amazon (there are many of course), but it was a waste of time. The battery works, but the faceplate is broken into multiple pieces and torn up around the edges, no matter how careful I was at trying to pry it up. I doubt the doorbell will survive the elements for too long. I put an Elago silicone cover on it (covers most but not all of the broken areas).

Nest/Google should be required to refund or replace these; a $250 doorbell that can't last 4 years (and isn't designed to have the short-lived part easily replaced) is defective by design.

And iFixit saying "do not be afraid to pull hard" on a thin piece of plastic that's heavily glued is part of the scam.
