Lime Battery ( Part 3 )

This time I tried to post something about Lime Battery. First I was curious and then I bought some lime in a shop in the market complex. The price is cheap Rp 1000 each piece. Then I use a copper and nails which previously used to arrange a potato battery.

Finally, the results are surprising. 4 pieces potato and 4 Cups salt water usually only produces a voltage about 2.8 volts. But the 4 pieces of lemon can produce voltages up to 4 volts.

One thing I don’t understand is, when the battery is loaded LED, a third type of battery voltage drop to around 1.8 Volt.

I have not tried further to find the reason.

Potatoes Battery ( Part 2 )

In the previous post, I tried to make the battery from salt water, I just practice one of the many articles on the internet. This time I tried to practice something else, that is a battery of potatoes.

One evening I went to the market and buy some potatoes, first I bought just to boil and eat it. Somehow after seeing a YouTube video and some internet articles, I became interested to make battery from potatoes.

I took some copper wires in warehouse, then I took a few nails made of aluminum. Of course, the copper cable is used as the positive pole and nail as the negative pole. This is a picture of copper and nails that I use.

One potato produce 0.7 volts, so if 4 pieces of potato are arranged in series will produce 2.8 volts, this value is enough to turn on the Red LED lights. the measurement results are almost the same with the salt water batteries on the previous post.

For more details, you can watch on this video.

Finally I’m so hungry, and then I boil the potatoes in water heater…..ha..ha…ha…

Salt Water Battery ( Part 1 )

I have seen many more articles on internet about salt battery, I was curious and tried it.

My first experiment was failed. I tried to fill a large container with water and salt. And then i put copper and aluminium into water for positive and negative pole. I have measuring and the result is only 0.7 Volt. I knew that this is not enough to turn on the LED. You can look at the picture below.

My second experiment was succeed, I took four small cups and fill them with salt water. After that I tried to connect each positive and negative pole thus forming a series circuits. And then...taa..daaaaa..........

my red LED has been lit. I have measuring and the result is 2.8 Volt. This voltage value is enough to turn on the LED.

I have observed that LED still lit after more than 5 hours. For more detail you can watch this video.

Thanks for watching and visiting my blog. :)
