How to recover a non-charged rechargeable battery?

Many users now use rechargeable batteries in electronic products. These batteries can be recharged, which saves a lot of money and sometimes causes problems such as non-charging. However, there is a very simple solution. Recovering non-rechargeable batteries from charging is much easier than you might expect.
The Lenvid channel, which prepares a short video to illustrate this, describes this simple process. You need two different things to save the battery in your hand. One of them is a metal tong that is in everyone's house and a fully charged battery. After that, all you have to do is put the negative side of the non-charged battery and the negative side of the fully charged battery together and hold it with a metal tong.
Stating that it is enough to hold both batteries in this position for only 30 seconds , the channel states that this technique works most of the time . Some poorly charged batteries cannot be brought to life even in this way.

Do not dispose of the rechargeable battery immediately.

The technique shown in the video looks really easy. There is no risk of harm to people, the process can be used actively in AAA batteries as well as AA . At this point, let us not mention. Whether you buy a rechargeable battery or a lithium-ion battery, always choose quality options. Don't be your expensive electronic product or your health because of a small savings.

Rechargeable Battery or Disposable Battery?

What is the difference between rechargeable batteries and non-rechargeable batteries? What type of battery should you choose when?

Most modern devices today use lithium-ion batteries that are capable of charging. However, there are still some devices that ask you to open the cover and place a few "pen batteries" in it.

Suppose you have a battery-powered device that you will purchase and assume that you need AAA batteries for this device. Which type of battery should you buy? Are rechargeable batteries better or disposable batteries? The difference is often hidden in the cost and technology used.

How Do Batteries Work?

Each battery has one positive and one negative connection. The positive connection is connected to the cathode and the negative connection to the anode. The cathode and anode pair are known as electrodes. Chemical reactions take place at the electrode that covers most of the battery. Electricity is the result of these electrochemical reactions.

Batteries work with oxidation and reduction. The anode oxidizes, which means it loses its electrons. At the same time, the cathode absorbs electrons in a process known as reduction. This process occurs only when the load between the two connections forms a circuit. This load is your device.
Why can't we charge all the batteries?

All disposable batteries are alkaline, ie cathode, manganese oxide, anode is made of zinc powder. The electrolyte (e.g., alkaline moiety) is formed from potassium hydroxide. The energy-producing reaction eventually erodes the anode and begins to inhibit reactions. At this point the battery dies.

There are several types of rechargeable batteries. Lithium ion batteries are used in phones and laptops. These batteries use lithium cobalt oxide as the cathode and carbon as the anode. Unlike disposable batteries, electrons can be transported from the cathode to the anode by providing external electric current.

However, instead of disposable batteries, the batteries are not lithium ions, but nickel cadmium (NiCd) or nickel metal hydride (NiMH) batteries. In NiCd batteries, the cathode is nickel and the anode is cadmium. These batteries lose their total charge capacity after several hundred charges, so they are not perfect.

Nickel metal hydride (NiMH) batteries lose their charge much slower than where they stand when compared to NiCd. A NiMH battery that has been on the shelf for one year retains much of its capacity. The total charge capacity of these batteries is 2-3 times higher.

So why are not all batteries charged? This is because of the cost. The materials used in disposable batteries are less expensive and are very suitable for devices with very low power. Lithium ion batteries are more expensive to produce and can produce plenty of power. The cost of nickel cadmium and nickel metal hydride batteries is in the middle.
Which Type of Battery to Choose?

This depends on your needs and budget. Disposable batteries cost much less in advance. Imagine you need to buy a few flashlights, a digital camera, a joystick, a radio, a fire alarm and a thermostat. If you buy a rechargeable battery for all, you can exceed $ 100. Instead, you can choose to buy a dozen cheap batteries for 15-20 TL.

However, particularly cheap disposable batteries will last much shorter than other disposable batteries. Here, of course, how much power the devices you use is important.

For devices that use faster power, such as a camera or joystick, you should use rechargeable batteries. For example, you can use a dual-charge battery of $ 20 several times. If you think about the environment, you have to choose the rechargeable battery. So instead of using hundreds of batteries in a few years, you can handle ten batteries.

Let us mention that the brand is important for rechargeable batteries. Duracell, Energizer, Panasonic and Sony have rechargeable batteries to choose from and offer a variety of options.

Identifying True and False Lithium Batteries

With the development of people's standard of living, mobile phone, laptop, digital electronic products, camera and camera are widely used in people's daily life. Lithium batteries play an important role for these high-tech consumer products. Most of the electronic products that are sold in the market, used batteries have basically finished switching to NIMH Lithium batteries but there are still some manufacturers imitating Lithium batteries using nickel cadmium and nickel for hydrogen batteries. How to identify the right and wrong lithium battery too?

The following methods are acceptable under non-professional conditions:

1, the same capacity battery lithium battery Nickel Cadmium Batteries feel lighter than nickel hydrogen batteries,.

2, use the battery charger Lithium battery charger. If the battery is Ni MH, the battery and nickel cadmium battery are heated during the charging process. If the temperature is not changed greatly, it is Lithium battery.

3, battery, negative electrode "instantaneous" short circuit, cadmium battery nickel, if still "electric" nickel hydrogen battery, battery "electric" like a lithium battery.

Recharging a battery properly

Connecting the phone to the charger before falling asleep is a routine for many phone users. By doing this, we seem to feel comfortable.

Almost all mobile phones come with a lithium rechargeable battery, which may be damaged by over-discharge or over-discharge due to its chemical nature. Someone can argue why I can't charge my phone all night. This is because most chargers are designed with a protective circuit to prevent overcharging / discharging. But what if the circuit doesn't work?

Here are some things to avoid when charging a battery:

Use a non-standard charger.

The battery does not charge until it is almost empty.

Recharge the battery even when the power is charged.

We recommend that a lithium rechargeable battery is between 45% and 75% of the power level and you can charge it for several minutes at any time.

Long charging hazard and deep charging of the lithium battery

Long charging may cause overload. When the battery is fully charged, the lithium battery or charger will automatically stop charging. Charging the nickel battery charger for 10 hours is not called “turbulence.. In other words, if your lithium battery is full, the charger will have a white charger. And none of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and that the quality will be perfect, so your battery will be in danger for a long time. This is another reason why we refuse to charge for a long time.

On some machines, if you do not remove the charger after charging for a certain period of time, the system will not stop charging, but will initiate the discharge-charge cycle. Perhaps the manufacturer of this approach has its own purpose, but it is clearly not good for battery life. At the same time, the long charging process takes a long time and usually needs to be done at night. In China's electricity grid, the voltage fluctuates in many places at night, and fluctuates a lot. As mentioned above, the lithium battery is very sensitive, much less resistant to charge and discharge fluctuations than nickel, which creates additional danger.

In fact, the shallow charge is more beneficial for the lithium battery. Only when the power module of the product is calibrated to lithium battery, you need to charge deeply. Therefore, products using a lithium-ion power supply do not need to be trapped in the process and everything is convenient and can be charged at any time.

The right way to charge lithium batteries

In summary, the most important tips for charging and discharging used lithium batteries are:

1. Charge the first three times according to standard time and procedures even for new lithium batteries;

2, when the machine is too low, you should start charging as soon as possible (do not wait until auto shut off);

3. The activation of the lithium battery does not require a special method and the lithium battery is naturally activated during normal use of the machine. If you insist on activating the “first three 12 hour charging method”, it will not actually work.

It is therefore wrong to use single-cell lithium batteries for the full pursuit of the 12-hour ultra-long charge and for automatic shutdown. If you did it the wrong way, please correct it in time, perhaps it is not too late.

Introduction and classification of lithium batteries

A lithium battery is a type of battery that uses a lithium metal or a lithium alloy as a plate material and uses a non-aqueous electrolyte solution. Because of the very active chemical properties of lithium metal, lithium metal is difficult to process and store. The cost of production is relatively high, so lithium batteries have not been widely used for a long time. Until recent years, with the continuous maturation and commercial scale production of lithium-ion compound and lithium battery separator technology, the cost has been greatly reduced due to light weight, large capacity, long life and lack of pollution. Lithium batteries will gradually replace lead-acid batteries and will become the main products. Power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aviation and various mobile power supplies, mobile phone power supplies, various emergency lights, flashlights, razors, cameras, cameras, photovoltaics. Street lamps and so on.

Lithium batteries are divided into two types: liquid lithium batteries, a lithium battery, a polymer lithium battery in which a lithium battery adopts a winding structure and has two types of a polymer lithium battery. The structure of lithium batteries is divided into two categories: split winding and stacked. The lithium battery structure then consists essentially of five large blocks: positive electrode, negative electrode, electrolyte, diaphragm, outer housing, and electrode cable.

The wound positive electrode film, separator and negative electrode film are placed sequentially and wound into a cylindrical shape or a flat cylindrical shape and are mainly represented by SANYO, TOSHIBA, SONY and ATL. The stacked type is stacked in multiple layers such as a positive electrode, a separator, a negative electrode, a separator and a positive electrode. All positive electrodes are welded together and the negative electrodes are welded together, mainly represented by ATL.
