A computer mouse does not require batteries because it is powered by a USB port. However, wireless mice may need double AA batteries.
A typical computer mouse will never require replaceable batteries because the energy required to power it comes from a USB cable connection. If you’re looking for a wireless model with replaceable AA batteries, then our recommendation would be to go for Logitech’s M325 or M510 models in order to get an accurate and comfortable design with up to 18 months of battery life and hours of use per charge.
