How to properly charge your phone battery for the first time? How to charge a car battery at home After buying a phone, how to charge the battery
When operating a car with working electrical equipment, problems associated with the battery of this car usually do not arise. Of course, if you do not leave powerful consumers of electricity on for a long time when the car engine is not running. But as soon as the fuse protecting the generator excitation circuit blows, the next attempt to start the car engine will not be successful. After which the car owner will be faced with a previously irrelevant question: “how to charge the battery correctly?” If a charger is available, properly charging a car battery at home is not difficult. Charging a car battery with an automatic charger is the simplest and does not require control over the process.
A car battery is used to start the car engine and as an auxiliary source of electricity when the car engine is not running.
Battery health assessment
The fact that a car's starter turns "sluggishly" is not necessarily a consequence of the car's chemical source of electricity being depleted. Therefore, before taking the car battery to charge, it is recommended to check it.
Measurements are taken when the car engine is not running. A fully charged car battery has an electrolyte density of 1.27 to 1.29 g/cm 3 and a terminal voltage of 12.3 to 12.9 V. When 70% of the charge remains in it, the density of its electrolyte will be from 1.23 to 12.9 V. 1.25 g/cm 3 and the voltage is from 12.0 to 12.1 V. A half-discharged current source will have an electrolyte density of 1.16 to 1.18 g/cm 3 and show a voltage from 11.8 to 12, 0 V. When completely discharged, it will have a density of 1.11 to 1.13 g/cm3, and the voltage will drop below 11 V.
Preparing the battery for charging
In order to properly charge the battery at home, follow this sequence:
Charge methods
There are three ways to properly charge the battery:
The first two methods of charging the battery have both their pros and cons. The first method is to connect the battery to a source of electricity with a constant current voltage of no higher than 16.2 V. The current strength when charging for 20 hours can be calculated if the battery capacity is divided by 20 hours. For example, your car has a battery with a capacity of 50 Ah, then 50 Ah / 20 h = 2.5A. With a 10-hour charge, to determine the battery charging current, the capacity is divided by 10 hours. That is, to properly charge the same battery in 10 hours, you need a charging current of 5 A. One of the most important advantages of this method is that the battery is fully charged. Disadvantages include the need to stabilize the current, significant release of gases, and heating of the electrolyte.
It is recommended to charge using this method in two stages - first make the charging current equal to 1/10 of the nominal capacity, and after the voltage of one bank reaches 2.4 V, reduce it by 2 times. The end of charging is determined by the appearance of intense gas formation - “boiling” of the electrolyte.
Alternative
The second method is to stabilize the charging voltage, while the current varies depending on the battery resistance. This technique allows you to charge the battery to 85–90%. Advantages of the method:
- quickly bringing the battery into working condition;
- Most of the energy consumed at the beginning of the process is spent on restoring the active mass of the plates.
The main disadvantage is the strong heating of the electrolyte due to the high current strength at the beginning of charging. Equalizing charging is designed to eliminate the consequences of deep discharges. It eliminates the increasing sulfation of electrodes very well.
The forced technique is used to quickly restore the operating condition of the source after a deep discharge. Allows the current to increase at the beginning of charging up to 70% of the rated capacity, but not longer than half an hour. Over the next 45 minutes, the charging current is reduced to half the rated capacity. For another 1.5 hours, the charge is carried out with a current of 30% of the rated capacity. This charging requires mandatory monitoring of the electrolyte temperature. If the temperature rises to 45 ◦ C, charging should be stopped.
I should use the method of forced battery charging as rarely as possible, since its regular use significantly reduces its service life.
About battery capacity
There is an opinion among car owners that it is inadmissible to install a battery with a higher capacity on a car, since with a larger capacity the car battery allegedly will not have time to charge. However, the amount of energy spent on starting a car engine does not depend on the battery capacity. Therefore, with a working generator, it will be replenished in batteries of larger and smaller capacity at the same time. This means that installing a battery with a capacity greater than recommended in a car will not cause harm. 
Charging device
The charger (charger) is used to charge electric batteries from an alternating current network. The charger consists of a voltage converter (transformer or pulse rectifier), a voltage stabilizer, a controller that regulates the charging current and sometimes an indication unit consisting of dial or LED ampere-voltmeters. Chargers differ in the type of batteries being charged, their operating voltage and capacity.
Charger designation for car batteries: X B/C, where X is the name of the charger, B is the maximum capacity of the battery being charged in Amp-hours, C is the maximum operating voltage of the battery being charged in volts. If the charger has a B value exceeding 170 Ah, then it can be used not only for charging, but also to help when starting the car engine.
Properly charging your mobile phone battery can extend its life, which is especially important for models with a non-removable battery.
How to properly charge a battery is not an interesting topic for many until a smartphone or tablet faces the problem of ineffective operation.
Many of us have had the problem of running out of battery while away from home and unable to charge it, but few try to use a method to prolong the life of this key element.
The battery has been designed in such a way that after 500 full charge cycles, 80% of its original capacity is retained.
Once this point is reached, your smartphone's battery (for most manufacturers, after 300-500 cycles) will noticeably lose efficiency.
One of the most frequently asked questions is whether it is necessary to wait for complete discharge and about the memory effect.
Memory effect in phone battery
If you charge the battery too often, this can occur in the so-called “memory effect”.
If you charge a battery that has another 20% of resources to a level of 80%, then it can “forget” about 40%.
This sounds strange, but fortunately only applies to older nickel-based batteries (nickel-cadmium and nickel-metal hydride batteries to a lesser extent).
Lithium ion (li ion) does not suffer from memory effect. In their case, you should do the opposite - charge often, but not all day, and don't let it drain to zero.
NOTE: Do not charge the lithium battery from 0 to 100%. If a lithium-ion battery is systematically discharged to 0 and then charged to 100 percent, its service life is reduced.
It will be very good if you charge the lithium-ion battery in the range of 20% - 80%. Try to keep the resource without dropping below 20%.
Some of the smartphones and tablets currently available are capable of recognizing when the battery has finished charging and turning it off on its own.
However, experts recommend disconnecting your smartphone or tablet from the power source if this is done for a long time, since there is a risk of overheating, which Li ion batteries strongly dislike.
How to properly charge a new lithium battery for the first time
A new battery should always be discharged to zero for the first time - until the smartphone turns off. After this, using the original charger, not only charge the battery completely, but also keep it connected for another 2-3 hours.
After fully charging the new smartphone battery, you use it as usual for the first time; it is not necessary to discharge it as quickly as possible, as was previously recommended in the old ones.
The main thing is to do a full charge the first time, after a complete discharge, and so on with a new battery 3-4 times. After this, go to normal mode.
How to properly charge your phone battery with a frog
There are universal devices - “frogs”. They are designed for lithium Li Ion batteries.
Charging is controlled by the phone's microchip and is automatically turned off if it is no longer needed, but frogs do not support this, they differ from each other and not all are of good quality.
If you find 3 or 4 contacts on the battery, then the 2 outermost ones are usually used. If the first green indicator lights up, then you did it right.
If it is not lit, change the polarity (CO button - polarity reversal). There are frogs that determine polarity on their own.
NOTE: The frog does not have charge control, so it is not highly recommended and is considered inferior to the original device.
Is it possible to use the battery fast charging system?
Many smartphones have a feature that allows you to quickly charge the battery (for example, in the case of technology, Motorola Turbo Charger charges in 15 minutes).
This solution is based on a special code that is powered at a higher voltage. Unfortunately, this is accompanied by a heating process, which is not a positive phenomenon in the case of a lithium-ion battery.
For the same reason, try not to leave your smartphone in the sun, because in the long run, high temperatures will shorten the battery life (its power will be significantly reduced).
Remember also that very cold conditions are also not favorable. Conclusion: it is better not to use the fast battery charging system.
Can I use any charger?
Use the charger that came with your smartphone or tablet, because then you can be sure that everything is correct. Cheap alternatives, unfortunately, can pose a threat to your phone.
Do not store the battery for too long on a zero charge. Leave her resources at 40-50%. Remember that an unused battery will discharge 5-10% within a month.
If you leave a dead battery for a very long time, it may be the end - it will no longer be able to charge.
Of course, it is unlikely that for such a long period, you will not be using a smartphone, tablet or laptop. This applies primarily to the spare battery. Charging batteries correctly can greatly affect their lifespan.
The process of charging a lithium-ion battery is quite complex, and cheap chargers do not take into account the characteristics of the battery.
Smartphones run out of charge quickly, and their charging is slow and ask for them much more often than older mobile phones. Good luck.
The main element of any device, regardless of its cost, brand and size, is the battery. Firstly, without this part, an electronic gadget turns into a completely useless thing, and secondly, the duration of operation of the smartphone itself depends on its technical characteristics. It is important to consider that a battery, even one with the highest potential, can quickly fail if used incorrectly. That is why there are many different opinions around charging rules, which can simply be boiled down to one question -How to charge your phone correctly so as not to damage the battery?
Every user knows that after a certain period of use of a smartphone, its battery fast discharges and therefore has to be charged more and more often and longer. The reason for this is not only the incorrect operation of the gadget, but also mistakes made when charging a new smartphone for the first time. The efficiency of the further operation of the battery largely depends on this factor. About,how to properly charge a new battery,there are a lot of discussions going on, and the standard advice is usually given:
a new phone must be completely discharged immediately after purchase;
then charge the smartphone again and let it work again until completely discharged;
do this procedure three times.
But, before you start performing all these steps, you need to find out what type of battery it has and read the recommendations from the manufacturer. As a rule, all modern gadgets are equipped with new types of batteries: lithium-ion and lithium-polymer. They have completely different technical characteristics than their outdated nickel predecessors, which, although they held a charge for a long time, had one drawback, which was called the memory effect. It was from old batteries that the advice about three charging cycles remained. Therefore, today users should be more interested in the question -how to charge a new lithium-ion battery,which, most likely, is on his new gadget.
Correctly charge a li-ion battery
Lithium-ion battery is a new type of battery that has high power and safety, and has no memory effect at all. Therefore, it does not require any complete discharge and charge cycles. But there are a few tips to keep in mind when charging this battery that will help increase the life of the battery:
lithium batteries do not like either low or high temperatures;
optimal state of charge from 40% to 60%;
wireless The charger should be used when necessary, since such devices always generate excess heat, which negatively affects the condition of lithium batteries;
It is very necessary to remove the battery from the phone carefully and always when charging is turned off;
Many people are also interested in the question m Is it possible to use a smartphone while charging?In principle, this can be done, but the processenergy gain will slow down significantly. And most importantly, so that your smartphone does not run out of charge at the most crucial moment, you should always have a standard charger with you. But if for some reason socket is unavailable, then they will help USB, which will allow you to connect to a laptop or portable charger at any time.
How to extend the life of the battery of your smartphone, for example, Samsung on Android, or with any other OS?
Given the wide range of applications and versatility of new smartphones, especially those with the Android OS, it is not surprising that battery life has always been an issue for developers, manufacturers and users themselves.
On average, most smartphone batteries last from one to two days until they are completely depleted and require recharging.
Both power levels and battery life can be extended if managed effectively.
Without carrying a charger (there is no way to use it) or backup power, you must minimize energy consumption.
This applies equally if it is lithium polymer, lithium ion, removable or non-removable.
How to properly charge a new battery for the first time in an Android smartphone and others
First, let's look at what to do with the new battery. New batteries must be fully charged before first use to obtain maximum power.
Nickel-based batteries should charge for 16 hours when first turned on and undergo 2-4 full charge/discharge cycles, while lithium-ion (li ion) batteries take about 5-6 hours.
Avoid completely discharging lithium batteries. Unlike nickel-cadmium batteries, lithium-ion batteries decrease in life with each full charge.
Therefore, you need to charge them when the battery indicator shows one stick. Lithium-ion batteries only support a certain number of recharges.
How to extend the life of the battery in an Android smartphone or any other
Store the battery in a cool place. Of course, you can't control the weather, but you can avoid leaving your smartphone in a hot car or in direct sunlight.
Also, check the battery while charging. If it is excessively hot, the charger may be faulty.
Charge the battery correctly according to its type. Most new smartphones have lithium-ion batteries, while older ones usually have nickel batteries.
Read the label on the back of the battery or the specifications in the manual to determine the type.
Useful tips to extend the life of your smartphone battery on any OS including Android
Nickel-based batteries (nickel-cadmium or nickel-metal hydride) typically suffer from a phenomenon known as the “memory effect.”
The “memory effect” comes from biochemical processes in the battery and in many cases is misleading to consumers.
If you partially charge a battery a large number of times, the batteries “lose memory” and do not fully control the entire charge.
Nickel-based batteries suffering from memory effect can be restored by completely discharging and then fully charging (sometimes several times).
A good rule of thumb for this type of battery is to completely discharge it once every two to three weeks.
Lithium-ion batteries can be maintained by carefully recharging them under partial load. They do not require “refurbishment”.
Regardless of battery type, only use a charger suitable for your battery and stop using a charger that causes excessive heat.
Store batteries properly. If the battery will not be used for some time, remove it from the smartphone and store it in a cool, dry place.
Lithium-ion batteries are not designed to operate in cold temperatures, so let the battery sit “out of the refrigerator” for at least one hour before using it again.
Over time, dirt can accumulate on the contacts, which reduces the efficiency of power transmission.
Clean them with a cotton swab or isopropyl alcohol. If the contacts are made of two different metals, such as gold and tin, corrosion known as "bimetallic or galvanic" occurs.
Solvents such as acetone are then often required to clean up such contact corrosion.
Be careful: this solvent dissolves plastic, so use a Q-Tip to avoid damaging the battery case or the smartphone itself. Good luck.
Almost all new smartphones suffer from one problem - they discharge too quickly. Many users remember with nostalgia those times when a mobile phone “kept its charge” for almost a whole week. This is the price to pay for constantly increasing power and performance.
In such a situation, the question becomes more relevant than ever: how to properly charge a new smartphone?
Each of us has probably heard that a new mobile phone needs to be charged in a special way so that the battery subsequently holds a charge longer. Taking into account the problem described above and the fairly high cost of modern smartphones, I want to save myself from any problems.
Even in the store, the sales assistant usually mentions how you need to charge the phone after purchase. You can also find entire instructions from manufacturers and various specialists on what to do.
The most commonly expressed advice is the following:
· The phone needs to be allowed to work for a while, and then fully charged;
· You need to complete 3 full charge/discharge cycles;
· After purchase, the phone must be installed immediately and then charged for 12 hours.
From this it becomes unclear, so how to charge a new phone? Is it necessary to "bleed" the battery? And what exactly should you do so that you don’t need to change the battery in six months or a year?
Battery Features
The bottom line is that batteries, like the devices themselves, are constantly being improved, so the characteristics and requirements for operating conditions are constantly changing. And the advice, in turn, remains the same.
Before you start “pumping” the battery or putting your phone on charge for a whole day, it’s worth finding out what type of battery is installed and what recommendations the manufacturer gives.
Battery types
The battery is a fairly important part of any mobile phone; it’s just that behind the design, performance and other new “tricks” they are usually forgotten about. Engineers from leading companies in the world, in turn, are working to improve mobile batteries.
There are several varieties:
· Ni-Cd (Nickel-cadmium);
· Ni-MH (Nickel metal hydride);
· Li-ion (Lithium-ion);
· Li-Pol (Lithium polymer).
Nickel-cadmium and nickel-metal hydride batteries were used in older devices. If you still have a handset with a monochrome or simple color display, then it probably has Ni-Cd or Ni-MH.
They were distinguished by a fairly high degree of reliability and durability, but very high power. There was another drawback - the “memory effect”. Over time, the structure of the electrolyte changed, so it was recommended to fully charge and discharge it at least from time to time.
This is where the advice about charge-discharge cycles came from.
Nickel batteries have been replaced by lithium batteries - Li-ion and Li-Pol (lithium-ion and lithium-polymer). They are used in almost all modern smartphones, laptops and tablet computers. Therefore, you need to know how to charge a new smartphone with just such a battery.
Their advantage lies in their small size, fairly high power and safety. They have almost completely no “memory effect”, so they do not require any charge-discharge cycles. Now developers are still working on improving these types of batteries, trying to increase durability and reduce dependence on various operating conditions.
Tips on how to charge a new smartphone
As already mentioned, the batteries of modern smartphones are practically independent of any operating conditions - manufacturers are constantly working on this. Although it cannot be said that they manage to do this 100%. In this regard, sometimes certain problems arise, and some of them arise precisely because of ineffective recommendations.
There are a few tips to follow:
· Lithium batteries are sensitive to low temperatures, so it is not recommended to use smartphones outdoors for a long time in winter, but it is better to carry them in internal pockets;
· For lithium batteries, the extreme states - completely discharged or fully charged - are not very useful, so it is better to leave a few percent;
· The optimal state for lithium batteries is 40-60% charged; in this state they can be stored for quite a long time without any problems. That is why in stores the charge of a new smartphone is always at this level.
Thus, there are no particular difficulties in how to charge a new smartphone. You should not “run” it on a full charge - this is not very useful for it. You should not leave it in the cold for a long time, otherwise the AB may lose its potential. Although new models are usually made less susceptible to low temperatures.
It is always better to have a standard charger, USB cable or car charger with you, and periodically recharge it during the day if possible. If you can connect it to a laptop or outlet for at least 20-30 minutes, then this is enough, and most likely the smartphone will not die at the most inopportune moment.
If necessary, you can purchase a higher-power battery or simply have a spare one with you. In this case, you can save yourself a lot of problems and not be one of those who constantly complain about a discharged mobile phone.
