1. The power consumption of the entire mouse circuit
2, the capacity of the battery (for example, the rechargeable battery has more than 900 MA, 1200 MA) the capacity is large and the use time is long
3, frequency 1, wireless mouse generally use 7 battery. (Also useful No.5 battery, relatively less) 2, there is no wireless mouse like a mobile phone battery, because the voltage is different, the mobile phone battery is a lithium battery, the voltage is 3.7V.7 battery is 1.5V after two sections in series. Can use No. 7 rechargeable battery (a voltage is 1.2V) 3, the advantage of wireless mouse is that it does not need to drag a line on the mouse, and it is flexible to use.
