AOLIKES 3.7v 503040 600mAh Lipo Battery Replacement for Cozmo Vector Robot SkyBell HD Video Doorbell Flysight FPV Watch Dash Camera GPS Driving Recorder Wireless Speaker (1)

My Skybell HD was behaving very erratically - the LED was always flashing different colors, or was off altogether. Seldom was in a solid green (normal). It turns out that the internal battery was swollen and no longer able to hold a charge, so the Skybell HD was repeatedly shutting itself down (no LED color) and then rebooting (solid yellow LED) in an endless cycle. There was no error code generated because the old battery was still reading the correct voltage, despite being unable to hold virtually any charge.Now, after replacing the battery with the AOLIKES 3.7v 503040 600mAh Lipo Battery, everything is working perfectly again. After booting itself up and resyncing with WiFi, the Skybell HD now shows a steady green LED, just like new.TIP FOR GETTING THIS BATTERY TO FIT: The bottom corners of the foil wrap on the battery that I received were not folded down properly. Thus, I could not get the replacement battery to fit. The corners were sticking out like two spikes on the bottom of the battery (the opposite end from where the circuit board and the wire connection are located) making the battery a millimeter or two too long. The foil wrap should be folded onto the bottom, just like when wrapping a package. The fix is simple: holding the bottom corner of the battery at a slight angle against your table top, push down firmly to bend the protruding foil wrap flat against the bottom, then do the same for the other bottom corner. Make sure the bottom is now nice and flat, and the battery will now fit - snugly, but it will fit - in the compartment.Make sure that the polarity of the wires correctly matches the old battery (mine did), connect the new battery to the circuit board, and reassemble.This is also a good time to clean the doorbell wire contacts with isopropyl alcohol, and apply a new gasket if needed.Be sure to properly dispose of the old battery at a recycling center.Good luck.

Easy to replace old battery with this one-took only a couple minutes. Remove old doorbell by one screw on bottom of doorbell, remove 4 screws on back of doorbell. Take picture of old battery so you get the two wire colors in the right spot. Plug in wired, Slide battery sideways into battery slot-put back and 4 screws in place reinstall on wall using the bottom screw and reset doorbell. Good to go!

Perfect fit for the SkyBell HD (Round one).The power plugged easily onto the board.The original battery was obviously gone bad as it was swollen.My SkyBell started acting weird and shutting off completely.

This battery is too wide and long to fit into the battery compartment of a Skybell Slimline camera doorbell. Pics show the packaging is tight and can't be folded as some reviews suggest. Other posts suggest using a Dremel to enlarge the battery compartment, but that would mean grinding all the way to the outer base. Battery sits on top of the compartment, but won't snap back onto the base. Best to look at other options! Unable to evaluate the quality of the battery.

The battery was the same size of the old one and I replaced it in my doorbell camera.The doorbell camera was over 300 dollars if I had to replace it while the battery was 27 with shipping .

I used this to replace the battery on this item: https://www.amazon.com/LIKNEG-Kids-Camera-Toys-Girls/dp/B09M63335F/It's working great so far, not sure how the battery life will be long term. However, a note: that camera battery has the polarity swapped and it's the only 503040 that I've seen that has the polarity that way. Despite the markings on the camera battery saying otherwise, the terminals were swapped. So if you are replacing the battery for this device, you'll need to swap the wires on the connector. Just use a small screwdriver to slide the plastic holding the wire in place.

Just got this. It fit directly into the skybell hd round model doorbell. Be careful of other similar batteries. This has the correct size connector at 1.25 the ones with a. 2.0 connector are too big. Solved my problem and my doorbell is working as normal now.
