How to make a battery from a matchstick outdoor and water. it's easy and fun. This is actually not a battery but a mini power generator so it doesn't need to be charged. This battery is long-lived with small magnesium rods that can last up to 6 months or more.
The main ingredient :
1.Outdoor Matchstick (Magnesium Rod)
2. Copper Wire
3. Drinking water
4. Plastic Bottles
Each battery cell can generate DC electricity of about 1.2 volts to 1.5 volts, and has a power supply of 20 mAh to 100 mAh (milli amperes per hour). You will notice that the ampere range is quite wide.
It is difficult to say what will allow the battery to operate at optimum efficiency.
You should try different metals to maximize the results, which metal is the best.
Or if you don't mind if the magnesium bars run low, you can add a little salt to the tap water solution in the jar, and this will allow your battery cells to produce more energy!
