I took a chance this battery would work as a replacement for the dead one in my X-Sense driveway sensor. The battery fit the available space exactly but does not have the correct connector to directly plug into the sensor. I was able to make it work by cutting off the attached connector and splicing the connector from the X-Sense OEM battery to it. The sensor is now returned to service and working properly. Please do not attempt a modification like this unless you have the correct tools and accept the potential damage you can cause to your sensor. There is limited space in the sensor case so you will need properly sized crimp connectors and heat shrink tubing to protect the circuit board from contacting the splice.

Fit my Bose Sound Color II perfectly with some soldering. Has better capacity than original and keeps the music going longer. . Just not sure how long the battery will work. Sometimes off brand batteries don’t live long. Time will tell.

I used these in an Arduino and a Particle Argon project. Even with the Particle Argon running and 6 NeoPixel LEDs on constantly, this lasted at least 6 hours. I went to bed so I don't know the exact time. And, yes - it will power a 5V Arduino device and NeoPixel string.

Installed this replacement battery in one of our solar powered lights on our backyard shed. It works fine when fully charged; however, I have noticed that it does not last as long as the original battery.
