Home Made Battery

This is intended to be the beginning of a series of posts about making batteries from home. It is going to include a series of test in order to determine the best types of home made batteries to use to power my home. The basic objective is to make a battery bank large enough to power several 12 volt lights and appliances throughout my home. I don't intend to power any large appliances yet, however that may be a goal for the future. For now, my intention is to be able to power at least  enough lights for up to 5 rooms, two internet routers(a cable modem and a wireless router), a 12 volt cooler for food, a PC and a TV. For me, those are the bare necessities and I can live quite comfortably with just those things. Others may require more, but this is my house, not theirs lol.

General experiments

I have already performed some general experiments with different sized containers, different types of container materials, different metals and various electrolytes. Below are my basic discoveries to get us started.

How to make a basic home made battery

To make a general purpose home made battery you generally need to make several cells. For this demonstration, we will use one 12 oz pop cans for each cell in our battery and we will probably use 6-8 cells depending on how much power is needed.


  1. 6-8 12 oz pop cans(preferably generic and not Coke cans) I find that generic soda cans are less likely to have a coating on the inside that prevents effective corrosion which is needed for the battery to work. If you have to use cans with this coating, you'll need to remove the coating with sandpaper somehow first. I've heard of using hydrochloric acid, but I cannot safely recommend that here, so don't do that unless you know what you're doing and understand that it is strictly at your own risk!
  2. roughly a 6 feed length of 1/2 to 1 inch in diameter copper tubing or another equally substantial amount of copper with similar or greater surface area.
  3. approximately 4 feet of medium gauge wire that is between 10 and 20 gauge.
  4. Either solder or aligator clips can be used to fasten your wires to the battery's electrodes
  5. A decent pair of wire cutters and strippers.
  6. Water. Good old H2O or Plain tap water works fine.
  7. Bleach. Any kind will work, but I use the concentrated type for better results. I've heard using Clorox brand works better too, but I refused to buy a name brand bleach for testing.
  8. Salt. Regular table salt. You'll need several tablespoons or about 2 tablespoons for each cell at the most.

Those are the things I"ll be using for my first experiments and these items were selected based on my preliminary testing.

Putting it all together:

It's not really hard to build home made batteries, but it is time consuming because you have to produce several cells and run some parallel and some in a series until you get the voltage and amps required. Here are the basic steps:

  1. Take 1 of your 12 oz soda cans(you could use larger or smaller ones too) and clean it out.
  2. Measure your can from top to bottom and cut a lengh of copper tubing(or other copper material) to approximately 1 inch longer than the can.
  3. Wrap one end of the copper tubing with electrical tape so that when you stick it down in the pop can, it doesn't ground out to the bottom of the can(or make sure it just doesn't touch the bottom if you don't want to take it. Then place a mark on the copper tube where it meets with the top of the pop can.
  4. Fill the can with plain tap water from your sink.
  5. Using the mark you made on the copper tube from step 3, wrap enough electrical tape around the copper so that you can fit it firmly in the mouth of the pop can. It should be a little snug at least with the tape around the mark keeping the copper from touching the can at any point. It is important the the two metals never touch or your battery will never work!
  6. After inserting the copper tube into the can, solder or clip a 2 inch length of wire to the portion of the copper tubing that sticks out above the top of the can.
  7. Solder or clip another length of wire 2 inches or longer to the rim of the alluminum can. This will be your negative lead and the one on the copper will be positive.
  8. Hook your leads to a multimeter and record the voltage and amperage from the single cell bettery you have just completet. You should get about 1/2 volt and very little amperage.
  9. Continue to make a total of at least 6 cells by repeating all the above steps. Label each cell you have made from 1 to 6 or 1 to 8 etc., depending on how many you made.
  10. Connect the positive lead(from the copper tube) of cell one to the negative lead of cell 2. Then the pos lead from cell 2 to neg lead on cell 3......continue until all cells are wired together in a series.
  11. Measure the voltage from the negative terminal on cell one and the positive terminal of the last cell and you should have between 6 and 16 volts so far.

That's basically all there is to it, but now you will know if you need more cells in series or in parallel depending on if you need more voltage or amperage. Add more cells in series to increase voltage and in parallel to increase amps. Also increase the amount of bleach and/or salt in each cell to increase voltage, but remember that the stronger the solution is, the faster the battery terminals will corrode and eventually need maintenance and/or cleaning to keep them producing the optimal voltage and amperage needed.

Size of container

I've tried everything from Popsicle trays(like larger ice cube trays), aluminum cans and 5 gallon buckets. What is the difference in the size of the battery you ask? Surprisingly very little. Whether using a 5 gallon bucket with large electrodes and 5 gallons of electrolyte or using a pop can, both batteries produced roughly the same amount of voltage ranging from 0.4 to 1 volt depending on the strength of the electrolyte solution.

Increasing Voltage

Electrolytes is the key to more volts within a single cell I discovered. While other factors can alter the amount of voltage only slightly, the strength of the electrolyte was the main factor that effected the amount of voltage the batteries Ive made so far produced.

To increase the overall voltage produced by your home made batteries, you need to increase the number of cells in the battery. A battery is often a series of several cells unless it is a single cell battery, but usually when I refer to "battery", I am speaking of the entire group of cells making up a single batter. A home made battery will often consist of 6 or more pop cans or other containers wired in a series or in parallel. To increase voltage we would run them in a series which means to attache the positive lead from the first cell to the negative lead of the second cell then continue until you reach the last cell. At that point the negative lead on cell one and the positive lead on the last cell will be open and those will be the two terminals used to power your device.

Increasing Amperage

The key to more amps seems to be in the general size of the battery. I was able to product significant;y more amps using a five gallon bucket as opposed to a 12 oz soda can.

To increase overall amperage a battery produces, several cells are required just as with increasing voltage. To increase amperage however, we have to wire the cells in parallel instead of in a series because batteries wired in parallel will cause the amperage to increase and the voltage to remain the same. Often times batters consist of a combination of cells ran in a series and cells ran in parallel to product the desired volts and amps. The general idea we are using will be to wire enough cells in a series to get 12 volts  in a single battery and after that we will increase the amperage by making several of these multi-cell/12 volt batteries and connecting them in parallel.

My First Battery

After testing large & small containers, a few different metals and several combinations of electrolytes, I ended up making my first batter with a series of 8 cells to product 12 volts at Work

Does anyone know if work online editing text is legit? I got an offer to edit email texts for $5 per kb and figure it is probably a scam. Can anyone confirm doing this work and actually being paid? They want you to work for 30 days before paying, so I am skeptical. Also, from Googling it, I can see that others are suspicious, but no one has confirmed it either way. I guess it's a common scam to get people to edit text first and then later they try to get you involved in Paypal and/or credit card scams. I'm waiting for that offer which of course I would not do, but if it was real, it would be nice. Usually when something online seems too good to be true, it is just that, too good to be true and therefore false. I'm interested to hear other's comments though.

From what I've heard, the scam, if it is a scam, goes like this:

1) they hire you to do some simple task like editing emails for a good amount of money($5 per kb) so that means you can make like $60 per hour, if you can type reasonably well, so that's a small red flat right there. This is as far as I've gotten so far. I have edited two emails so far and it took about an hour and I am supposed to be paid $75 for the work, but not for 30 days(red flag no. 2).

2) Then, they will ask you to work as a representative.

3) They will ask you to allow them to transfer money to your paypal account to handle transactions for them for one reason or another saying they can't due to some Paypal issue that they have. HUGE RED FLAG!!!

So, if they try to get me past step one, they will fail, but from what I've heard, others have done this, but with different companies. I've yet to confirm that is doing this scam or if someone claiming to be them is doing it or if it is in fact a scam at all. I suspect it is, but I have not been propositioned yet to do anything other than edit emails, so I will update this blog post if that does or does not indeed happen.

The reason this would be such a huge red flag is because supposedly, is owned by Ebay now. Ebay in turn owns Paypal. So, why would they have any issues with Paypal? They wouldn't. Period! So, while I am 80% sure at the moment that this is a scam, I have not yet confirmed it because I have not been asked to do anything other than correct emails. I suspect I will be asked though...

Update  05/10/2015

After attempting to inquire from my contact named Andrea Nelson, supposedly from, I have come to the conclusion that this is in fact a scam.  I simply stated to her that the work she is having me do is similar to a common scam and could she either, provide me with a verifiable contact phone number to a representative at that would confirm my employment, or, pay me for the first two tasks I had performed. I gave the second option because I know from my experience working online that a legit job will never mind making a small payment to prove they are trustworthy and a scammer will never pay you a dime. The amount I requested was only for $75 and the amount of work they had asked me to do before receiving a pay check would of totaled over $1000, so it was not too much to ask. I normally collect 33% of all jobs I do through without any problem at all, so it is a very good indication of a scam if they are not even willing to pay a fraction of that to prove they are for real. I concluded that this was a scam after she didn't reply for the first time within 24 hours. I'll document anything else that happens here, but I suspect it will be all things I have done to attempt to collect the debt as I don't expect to hear from them for some time.

So far I have only told them that I plan to exercise my right to collect the amount due to me for services rendered within 24 hours after being dismissed from a job according to a little known U.S. law. I sent her a bill via Paypal to the email she has been using to correspond with me to date.

I don't expect her to pay. I expect to have to take further action, which I will just to make a point. I advise anyone that is scammed online to take action in order to help eliminate this inhumane practice.

Please comment on this post if you have experience with or a similar scam... Document it at least! It saves others from getting taken advantage of.
