Precautions for replacing polymer battery for wireless mouse

Replacing polymer batteries for wireless mice Most wireless mice use AA or AAA batteries, which are not very environmentally friendly to use. Today, with the high rate of cell phone obsolescence, many people leave countless lithium batteries idle at home, why not put them in a wireless mouse to use the waste heat to prevent the cumbersome and wasteful frequent replacement of AA batteries? The idea of u200bu200bimplanting lithium batteries Many cheap wireless mouse energy-saving technologies are not enough, and the cost of having to replace AA batteries for more than ten days is not acceptable to everyone. The good news is that as long as you have unused cell phone batteries in your home, they can also power the wireless mouse. However, there are several obstacles to inserting the lithium battery into the wireless mouse: you have enough hands; the wireless mouse has enough space to place the lithium battery. The following is how the reader fsice inserts a lithium battery into the Logitech K260 mouse. Directly attack the hardware required for transformation process transformation: 3.7v mobile phone battery×1, scissors/knife, 0.5mm cable, USB interface, the above materials can be removed from the obsolete equipment, theoretically it is possible to disassemble the mouse at zero cost, according to For battery capacity, use scissors and scissors to cut out the space for placing the battery. After fixing the battery, use two wires to weld the positive and negative electrodes of the battery respectively. Remove the USB interface from the old circuit board and connect it to the wire connecting the battery. Pay attention to the positive and negative poles. Usually the USB interface can be removed from the mouse’s battery storage, and then connected to the computer for charging. Further reading. If you don’t have equipment to solder, it’s no problem. For example, the modification method of reader’s abreuhairXiwind is to tie the wires together with tape, which is simplified. Steps of transformation. Summary of battery transformation and charging design Putting the lithium battery directly into the wireless mouse is just a relatively elementary conversion method. A 500mAh lithium battery can be used for the mouse for about 7~10 days. Readers with the ability can consider adding a variable resistor. In theory, it is possible. Get a longer battery life. In addition, by expanding this idea, we can also turn the wireless mouse into a wired one, or turn a limited mouse into a wireless one. More interesting conversion forms are yet to be explored by DIY players. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
