What To Do With Old Laptop Batteries – A study by IBM researchers has shown that most discarded laptop batteries are capable of providing enough energy to power homes in poor countries around the world. The team from India has done some research to test the feasibility of the idea and now the work is focused on improving the imaging system.
For most of us, lighting up our homes is as simple as flipping a switch, but there are also large groups without electricity around the world—in fact, more than 400 million people are without electricity in India alone. The World Bank estimates that adding electricity will cost US$8,000 to US$10,000 per kilometer. This is a serious problem that requires a sustainable, cost-effective solution.

This is where IBM research comes in. The Environmental Protection Agency estimates that about 50 million laptops or desktop computers are discarded in the United States each year, and many of them still contain rechargeable lithium-ion batteries.

The Bangalore-based team worked with research firm RadioStudio to remove used batteries, test and select working cells, add dongles to protect against acceleration and overheating, before creating recycled battery packs. They found that 70 percent of the discarded batteries could provide LED light for at least four hours a day, year-round.
The five refurbished batteries, known as Urzars, were distributed to roadside vendors in Bangalore, who reported three months later that the packs did their job admirably, praising their long battery life. In response to user requests for brighter bulbs and rat-resistant cables, the team is now working on a similar redesign of the battery.
IBM researchers envision a system that works with a network of solar power stations where users can charge UrJars for free.
The company currently has no plans to commercialize the technology, but believes it could be a viable, cost-effective way to provide off-grid power to developing countries.

Usually a laptop battery comes in a 3 cell pack and 6 cells are equal to 2 3 in a row
• If cell 1 means cell 2 are in parallel series, the BMS (Battery Management System) will disable the whole battery. However, cell 2 means two identical cells (or only cell 4) still have some life left.
• If the BMS (Battery Management System) does not work, it disables the entire battery with a 90% chance (6 individual cells) of survival

• BMS (Battery Management System) It measures the bad count and discharge and when another cycle is done it shuts down the battery (the manufacturer should do this for safety reasons) even though it has a 50% chance of finding a good cell.

If you use a laptop, after a few years of use the battery wears out and there comes a time when your battery has no power. This actually happened to me. So I thought it would be good to share what I did for the battery.
Have you ever wondered what’s inside a laptop battery? What kind of battery is used? Why are there 8 pins for battery connection?
Well, let me explain it. Inside the battery are actually 6 lithium ion cells. These are 18650 batteries. Cells are connected in different colors depending on the type or brand. Usually two rows and three cells are connected in a row and two rows are connected in parallel. The voltage of each 18650 cell is 3.7 V. So three cells in series give 12.1 V. Now if each cell has a capacity of 2000 mAh two parallel lines give 4000 mAh. So the battery provides 12.1V, 4000mAh.

Now there are 8 pins connecting the battery to the laptop. 6 of these provide power to each cell and 2 of these pins are electrical. The laptop monitors the cell voltage so that if a cell dies, the battery stops supplying power. Also these 6 PINs are used for payment.
When the battery dies, you will definitely be looking for a new one. But what to do with this loss? Don’t bother with it. Disposing of these batteries requires special procedures. A battery may be dead, but not all cells are dead. You can recycle the good ones and make a different battery, or you can use them to make a DIY power bank!
I have 2 dead cells out of 6. So I have to pass them anyway. But 4 cells work fine. So I decided to make a 2S Li-ion battery.
Charging lithium cells is very different from all other types of batteries. A charging system has two main components – constant current (CC) and constant voltage (CV). We need special chargers to charge the cell in these two stages. A commonly used charger is a balance charger. The name also suggests that they organize money. This means controlling the volume of each cell.

. It is much cheaper than other chargers. You can use any 5V to power the cells. But the main problem is that you can charge only one cell at a time or you can connect many cells in parallel. (This may be slower as you increase the number of cells).
There are many different types of chargers available in the market. Ultimately it’s up to you which charger you choose. I use Skyrc imax B6 mini charger.
Solder two batteries in series to form a 2S Li-ion pack. You can connect 3 of them in series to get 11.1V. Now whatever you do the choice is yours, make the connections accordingly.
I have a t 2S lithium ion pack so both cells are listed. Now solder the copper wire to the negative of cell 1 and the positive of cell 2 to connect them in series. Solder the middle wire of the connector to the copper wire (see attached photo). Finally, solder the red and black wire of the JST plug to the positive and negative wire of the JST connector and to the positive and negative of cell 1 and cell 2, then wrap the cells together and cover all the leads.

As there was a comment from Omnibot saying that there is a risk of lithium batteries exploding during welding. I found a safer alternative using battery cases. These batteries are available as single cells or with multiple cells.
If you can’t find the battery case, you can solder the terminals. Make sure you don’t burn the battery for more than 10 minutes.
So far we have made the battery. Now let’s test the battery with a proper charger. Connect the plug plug to the charger’s standard port and the JST plug to the charging port using the cable adapters. This adapter cable is supplied with the charger. Power up the recorder from a 12V DC source and when ready select LiIo from the main menu and then select LiIo Balance CHG. Set the maximum charge current to 1.0A (your charger may be higher, but 1A is the maximum charge for 18650 lithium cells. Do not use a higher charge, otherwise you may damage the cell or the cell may explode).
Note: It is recommended to use a good charger. I recommend the Skyrc imax B6 charger/discharger or any other Skyrc.

You will need a sharp knife or scissors and a small hammer to remove the particles. Hold the sharp side of the knife against the edge of the battery and press the knife gently. Repeat this process until you see the edges frayed. So get it out
