The rechargeable battery will power your Magic Mouse for about a month or more between charges. It’s ready to go right out of the box and pairs automatically with your Mac.” This Magic Mouse 2 model number is A1657 (EMC2923).
This wireless Multi-Touch mouse was 0.85 inch high, 2.25 inches wide, 4.47 inches deep, and weighed 0.22 pound. It shipped with a Lightning to USB cable for charging. It required a Bluetooth-enabled Mac with OS X 10.11 or later, and also worked on an iPad with iPadOS 13.4 or later.
