I was able to use these to change the battery in some toys i had found in a yard sale for my grandson. I needed 3 so this 10 pack worked out great. Everything is running fine and i have replacements for later. They are commonly used in car security (car alarm/keyfob batteries), organizers, glucose meter, camera, electric thermometer, calculator, computer equipment (memory backup battery), toys, communication equipment, electronic watches/clocks,data pack for video camera. #rankboosterrevivew #Sponsored #Innovator https://www.amazon.com/Innovator-Capacity-600mah-Button-Battery/dp/B073S5MP43
