diy 3.7 volt lithium ion hack so i don't have to keep buying batteries. - 3.7 volt lithium ion battery

Are you tired of buying batteries often to supply power? You are Instructables or other spare parts that require AA or AAA batteries, such as wireless keyboards like Logitech Premium 2.
4 GHz wireless keyboard, the box claims this is the best keyboard with very little battery power and the battery should last for a while. . . .
They are not folk.
At most a week or two, I use my computer, I love my wireless keyboard without a doubt, and I shudder at the thought of going back to the tether keyboard, so I did the best thing I could think.
I took an old LG trac phone and it had a good battery and was still working properly and solved my battery problem.
My battery doesn't need to be charged, but once a month, that is, keep the power on when not in use.
This is very simple to a large extent, and if everything is in the beginning, your time should not exceed 5 to 10 minutes.
Statement: electric tools such as electric drills and saws can easily hurt you, if you can ask my former friend Ray the time I used him to do the vise, he will tell you, it's terrible, don't do that.
Soldering iron can cause serious burns and fires, use in dry places, keep any flammable liquid away from your work area, and, be sure to put the fire extinguisher nearby, do not breathe in steam from flux or solder.
Please use proper care when using the iron.
I am not responsible for any damage to you or your computer, man or woman Cave, bat cell phone, car home, boat, flying saucer, if you continue to do so, jet planes or anything else you may or may not have.
As far as I know, it's dangerous enough.
Tools: soldering iron welding wire strips electrical tape to help manual operation: working mobile phone with battery and charger.
I use the Molex connector just because when I try to spend little or no money on anything I earn, that's what I have at hand.
You can use 2 Lead connectors of any type.
This is my LG Tracfone for this project.
Any old or new phone you don't use your service will work to make sure the phone has a good battery and charger.
As said before, this battery will last for 30 days or more, usually hard games and typing that are fully charged.
Each lithium-ion cell phone battery has a clear positive and negative mark on the battery.
Since I have made this battery, I am guiding you with some old photos.
Here I place a very small amount of flux on the positive and negative terminals.
You have to weld the battery with tin strips and tin strips as little as possible.
So the battery can be charged in the phone.
Once the wires are fixed, fix them with a few packs of electronic tape and put them into the phone for charging.
The project has now been completed.
So I never have to buy AA batteries for simple things like my keyboard, custom mod MP 3 player or my other teaching project, there are a lot of apps that can benefit from recycling these batteries and also keep these toxic little boys away from the environment.
