Review: Works great on Round Skybell video doorbell - 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!
Review: Exact replacement fit for original Cozmo - It takes a while to get Cozmo apart to the point of replacing the battery, but this is the battery that you want. It fits snugly since it's a little bit larger, but it holds a greater charge. There are videos on YouTube that show how to take Cozmo apart, all it takes is a philips head screw driver and some patience.

### ⭐⭐⭐⭐⭐ Exact replacement fit for original Cozmo

It takes a while to get Cozmo apart to the point of replacing the battery, but this is the battery that you want. It fits snugly since it's a little bit larger, but it holds a greater charge. There are videos on YouTube that show how to take Cozmo apart, all it takes is a philips head screw driver and some patience.

### ⭐ Skybell Slimline Replacement Battery
*by M***N on May 25, 2024*

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.
