I have the same issue as you guys but I am very hesitant to solder next to a lipo. I have a spot welder, which is how these were attached originally. I am going to see what I can do now that I have some replacement batteries and report back.

found this thread and https://amcrest.com/forum/viewtopic.php?p=47279#p47279 and now my AD410 is back in business. Appreciate all posts and suggestions.

thanks!

Thank you!

My doorbell had been going offline periodically, and we finally realized that we hadn't heard it in a while.
A little testing confirmed that it was rebooting on the button press, which felt like a battery issue -- I mean, how else could it close the doorbell circuit without going offline?

Found this thread, ordered the battery from amazon [602025] for $9, arrived the next day. The old battery was swollen, and it's been pretty cold this winter; doorbell was installed in 2021. Removed the battery manager chip from the old battery (easiest to remove with heat -- the welds are to the solder pads, not to the battery manager itself. If you heat the battery manager attachment pads, the old battery will detach), soldered it to the new one, attached the battery heater, reassembled, charged via usb for ~30 minutes, reinstalled.

After plugging in the doorbell to usb to charge, it powered on and resumed recording.
Everything is back in business: doorbell rings again. Great repair project...and only $9.

Thanks to everyone for their posts and pictures and advice!

I wanted to thank you as well! Worked for me even after my terrible soldering (I almost made the contact pad come off when I was trying to get the solder to stick - due to oxidizing the battery contacts). I thought for sure I messed up the board but it worked. I did find the battery was getting quite warm when charging with USB, hopefully that isn't a sign of something I screwed up.

If anyone finds a part replacement without having to solder the old board for the battery please post. I have a feeling if I need to do this again I'll screw it up - hah.

Hi All,

First, Superdave4444 thanks for the great photos of your process. I just replaced my AD410 battery to solve the issue of my camera going off-line when the doorbell was pressed. Worked perfectly!

Just a note; the battery contacts are tack welded onto the circuit boards (old battery and new battery) so you will need to "peel" them off very carefully with pinch nose pliers. I used a fine file to "smooth off" the pads once I had removed the original battery. After that, soldering the new battery back onto the original board was pretty simple (assuming you have some previous soldering skills ).

Good luck!

I also had the problem where the AD410 was restarting whenever the doorbell was pressed. I bought a battery

I think I chose one because it had three wires as shown in the one of the pictures in this thread.
It turns out that the battery was a bit bigger than the one in the AD410 and the connector was different as well.

Howevwr, I was able to gently pull the wires and metal clips out of the connectors on the old and new battery and put the new wires into the old connector.
I was also able to fit the bigger battery into the AD410 housing without much problem.

Reinstalled the AD410, gave it an hour to charge, and can now ring the doorbell, which now fully rings the mechanical chime (used to die half way through) without rebooting itself!

Curious which battery did you use? Still working?

I tried the Amazon and solder swapping the BMS, but I failed and the battery gets hot to the touch when I plug it in. I might have cooked my BMS, not sure. Polarity is matched correctly.

I did a sanity polarity check off the new battery with a volt meter and the printing was incorrectly marked. Another resolder and mine is working again.
