Technological progress is relentlessly racing forward. New technologies and devices appear. Rechargeable batteries have already ceased to be a fantasy, and passed into the category of vital necessity. But the choice of power sources is a personal matter. Someone tirelessly replaces one battery with another, and someone only renews the battery charge. But in order for the battery to work for a long time, you need to know and follow the rules for charging and using it.

In order for the battery to be rechargeable, it must be of a special, rechargeable type. To determine which battery is in front of us, you can read the information indicated on the case. Do not even try to insert simple, disposable batteries into the charger.
If you do not follow this recommendation, then the following is possible:
- if you are a lucky person, then nothing will happen;
- the battery may boil;
- overheating of the case will occur and, as a result, fire or explosion.
- may close the network.
It is precisely because of such probable consequences that you should not insert simple batteries into the charger.
In their shape, batteries are very similar to simple batteries. Among the batteries, there are the same types, except for the tablet shape. A limited number of tablets are produced. Tablet batteries are available for use with hearing aids.
Reference. Customers like the ability to recharge the battery. Buying them is more profitable than their classic counterparts, although their price is much higher.
The user may have a natural question: "How do you need to charge the batteries?" The question is correct, because in order for the battery to be operated for a long time, the charging process must be approached correctly. You cannot take and leave the battery on charge for two or three days. There is a simple formula to determine the exact recharge time, or you can use various services where there are calculators for calculating the time.
Why simple batteries won't charge
The appearance of batteries and simple batteries is almost the same. This leads many to mistakenly assume that all batteries, without exception, can be recharged. Naturally, this is far from the truth. All processes that take place in conventional batteries cannot be reversed. But in rechargeable batteries - it's easy.
The process taking place inside both types of batteries is based on the same principle. The energy of the chemical process is converted into electricity. A special substance is placed inside the batteries - an electrolyte. Electrodes are located in the electrolyte. As a result of the ongoing chemical reaction, a potential difference arises at the electrodes. As soon as the ends of the terminals are closed by a conductor, an electric discharge is transferred to it. Gradually, the number of ions is reduced and the battery power runs out.
What's the point of passing current through a simple battery? There is nothing to recover there and nowhere.
A completely different picture with the battery. In them, both the electrolyte and the electrodes easily return to their original state. In rechargeable batteries, the electrodes and the electrolyte itself can be restored to their original state.
How to tell if a battery is rechargeable
Considering that the appearance of batteries can be deceiving, because they are the same size, color similar, to identify them, you should carefully look at their labels.
If there is a label on the case, there are no questions:
- We look at what is written on the battery. If there is an inscription rechargeable, which means that we have a rechargeable battery in front of us, since the marking says that the device is rechargeable. If there is - do not recharge, it means that we have in our hands a simple battery that cannot be charged.
- In addition to these inscriptions, the capacity value is also indicated on the batteries, which is indicated by mAh, which means ampere-hours.
- Well, it's worth taking a closer look at the price tag - the battery will obviously be more expensive than a simple battery.
And if there is simply no label? In this case, you definitely cannot do without a tester. The voltage value of a simple battery corresponds to 1.6 volts, for batteries this parameter is 1.2 volts.
Battery charging rules
Before charging the battery, plant it completely, as they come from the factory already charged. And after it sits down, make a full charge. In the language of specialists, this procedure is called molding.
Attention! Do not interrupt the forming process. After placing the battery on a charge, do not remove it until it is fully charged. You can not only remove the battery, but also switch the charger to another outlet.
This process needs to be done four times. If you do everything according to the recommendation, you can significantly increase the battery capacity indicator, as well as extend its operational life.
In general, it is better to get into the habit of charging the batteries only when they have completely sat down.
Important! Never charge batteries when the ambient temperature is below five degrees or if it exceeds fifty degrees. The most favorable temperature for this process is in the range from twenty to twenty-five degrees. And do not overdo it in the charger, otherwise it may be damaged.
How to understand how long to keep on charging the battery
It may well happen that after putting the battery on charge and waiting for a while, you find that no charging has occurred. There is no need to suffer further. Obviously something went wrong. Maybe the battery itself is faulty, or maybe the charger.
The most important thing when dealing with batteries is to charge them correctly. And for this you need to know exactly and observe the charging time.
To determine this time, you can go in two ways:
- Go to one of the specialized sites and calculate everything in an online calculator. Everything is simple and straightforward.
- You can calculate this time yourself. For this, a formula has been developed.
The formula for calculating the charging time and its subtleties
To calculate the time required to fully charge the battery, apply the formula:
Time required for charging = battery capacity indicator / amperage * recharge rate at which one hundred percent charge is ensured.
The coefficient can be from 1.2 to 1.4
For this formula to work, the necessary factors should be taken into account:
- It takes four to twenty hours to charge the battery. No more, but no less. If the battery is charged earlier than four hours, the charger will automatically stop supplying current. The battery can already be used. If the battery does not charge in more than twenty hours, then the current is very low. In this state, the battery can remain in the charger for almost a week. It won't hurt him.
- The capacity value can be taken from the battery case, or you can find out from the information on the package or in the instructions.
- The current required for charging is written on the battery case, it is also duplicated in the instructions.
The time it takes to recharge is not constant. It depends on several factors:
- battery chemicals;
- ambient temperature;
- the amount of charge remaining in the battery.
Number of recharge cycles
When using rechargeable batteries, be aware that they are not endless. Their resource is gradually decreasing, and each new charge brings it closer. For example, nickel and cadmium batteries can be recharged 1,000 to 1,500 times. True, newer batteries can be recharged up to four thousand times.
The main thing for the battery is the first four recharge cycles. At this time, there is a "buildup" of the battery capacity, which will remain throughout the entire life of the product.
Do not be lazy to study the instructions for the battery in detail. They are written by intelligent people and thoroughly describe how the device should be charged.
Reference. Recently produced batteries, as a rule, can operate for almost three years.
How long does it take for the battery to charge
Calculating the amount of time it takes to fully recharge the battery is easy. To do this, we divide the value of the battery capacity by the charger current. Do not forget to take into account the coefficients. They range from 1.2 to 1.6.
To find out which coefficient should be applied, let's look at the difference between the current and the value of the battery capacity. The greater the interval between them, the greater the value of the coefficient we use.
Online calculators on special sites work on exactly the same principles.
