The total voltage of the lithium battery is 4.2V, which is much higher than the rated voltage of the mouse. It is not recommended to use it this way.
The lithium battery you are talking about is cylindrical, right? If you want to use lithium batteries, there are now lithium batteries with an output voltage of 1.5V. The appearance is the same as AA and AA size batteries, and an inverter circuit is added to the 3.7V lithium battery. Just look for 1.5V lithium batteries in Majia, which are more expensive.
It is recommended to purchase Biteli nickel-metal hydride batteries, which are manufactured in China. They are cheap and the quality is close to that of Sanyo. The working current of the wireless mouse is very low (lower than Sanyo). 20 mA), regardless of the brand of nickel-hydrogen batteries, they should be charged quickly when used to avoidexcessive discharge. As for lithium batteries, those of 3.7 V should not be used. You must use 3.2V lithium iron phosphate batteries.
