First charge of Li-Ion battery

Question

Iron

Do I need to charge the batteries for the first time before use (if it was already charged by the manufacturer somewhere up to 60%)
If I forgot to charge, does this affect anything?

Answer 1

I will be brief. How batteries should be handled depends on the technology they use.
Ni-Cd, Ni-MH is necessary to prevent a drop in charge capacity - discharge to zero before charging. Otherwise, there is an enlargement of elements that carry a charge and, as a result, the total capacity of the battery drops. It was from those times that “when buying, be sure to discharge, charge; repeat the procedure 3 times. This is true even now, only in the same mobile phones such batteries have not been used for many years. But it has not lost its relevance - through several cycles of deep discharge and subsequent charge, it seems like “dead” batteries are being restored. The fact that the batteries must be completely discharged and such deep cycles done is remembered and passed from mouth to mouth.
But progress did not stand still and slowly in most devices (I mean laptops, mobile phones, players) the batteries changed to lithium-ion and a little later lithium-polymer ones appeared.
But Li-Ion, Li-Pol are arranged quite differently. And they need to be handled differently. These batteries do not tolerate deep discharge - it is easy to disable them in this way. That is why devices are sold at 2/3 charged. And not at all so that the device can be turned on for verification.
But the ossification of people's thinking does its dirty work - they still go from mouth to mouth "how to properly charge batteries", without even emphasizing what type they are talking about. What is good for a Russian is death for a German - and they don’t know.
But start asking - “do you even know the physics of the process?”, “What happens there when charging, discharging, why is it possible, why not?”. They cannot say. A friend said ... so thousands of delusions have been running on word of mouth for decades.
Therefore, supporters of "discharge-charges" of Li-Ion batteries, please write in detail what they base their opinion on, because science and practice are not on their side.
They even need to be stored (when you don’t plan to use them for a long time) in different ways - nickel-cadmium and metal hydride ones need to be completely discharged, and lithium-ion and lithium-polymer ones, on the contrary, charge up to 60-80 percent.

Answer 2

I think both previous commentators are right in their own way. Although the second is certainly more to the right.
The most normal option for using lithium batteries in terms of efficiency is to charge it as little as possible, discharge it and keep it on charge more often. And try not to discharge completely - because then it quickly degrades.
That is normal everyday use. Full discharges will shorten its life faster.
If you will not use the battery for a long time (it lies in the closet), then the most correct way to store it is to charge it by 50-60%. That is why manufacturers supply gadgets with such a level of charge in the battery.
On the other hand, it is very difficult for the device to determine what kind of current charge is in the battery. They can reliably determine only the dynamics of its work. Therefore, in order for the device to correctly determine the current battery charge, many manufacturers recommend completely discharging it and charging it for the first time. This is called battery calibration. That is, the point here is not at all in him, but in the device that you use. Just read the instructions for your device and if it says to discharge charge, then do it. If not, then kill it.

Answer 3

In fact, I will say the opposite of the previous speaker

first you completely (until the last breath) discharge

Immediately shortens the life of a Li-Ion battery
There were several articles on Habré about this with tests. NEVER allow a Li-Ion battery to be discharged to 0 (in fact, even at 0, it still has about 3% charge, so it is advisable not to test this reserve and not keep it discharged).
I think that the advice to discharge to 0 / charge is very stupid, because if it were necessary, the battery manufacturer himself would have done it at the factory for the sake of his own reputation.

Answer 4

It is believed that in order to “train” a new battery, first you completely (until the last breath) discharge the phone. Then also fully charge. And then repeat this process one more time. In other words, you do not need to immediately charge it before use, you need to completely discharge it (before turning it off), and then fully charge it as well.

Answer 5

never understood why it is impossible to “train” the battery with charge-discharge cycles in production?

Actually, this is exactly what they do in the production of batteries, pletinsky pletinsky said everything correctly!
ps Today I came across instructions for charging a li-ion battery to a screwdriver and it says there you need to discharge and charge. Campaign writers of instructions are sitting grandfathers who do everything the old fashioned way

Answer 6

Ni-Cd and the like need so-called "training" because they have a memory effect, and some Lo-Ions also need such training, but only those Li-Ion batteries that have a controller chip, so it is calibrated - then yes memorizes min. and max. charge. And the way to calibrate the battery controller depends both on the controller itself and on the device on which it is installed (for example: phone) Therefore (this is my opinion) there are so many ways to calibrate. For example, for some phones, the charge controller is in the phone itself, and for some it is placed outside of it, i.e. in charge. So imagine what happens to the battery if you charge it with a non-native charger on your phone without a charge controller.

Answer 7

I would stretch this topic a little, since experts in chemistry and physics do not always understand that lighting a light bulb with a volt column in a lesson at school and the demands of modern technology are not at all the same thing! Li-Ion Batteries without chip controllers, such as one-piece non-monoblocks with a block of parameters, for example, for scooters, motorcycles, gyro scooters, or cans of the battery type, simply soldered together in screwdrivers, do not need discharge-charge cycles. But Li-Ion batteries with chip controllers that are in modern phones, such as iPhone, Haomi, are also found in restyling hybrid cars in a monoblock. The battery manufacturers themselves in the recommendation write what you need to do about 3/5 charge-discharge cycles the first time you turn it on! since the battery from production comes with a zero cycle, you can’t let the controllers record an incomprehensible volume, after all, the battery can lie for a considerable time in warehouses before it reaches the buyer! And a visible charge of 50-30% is not a half charge in production, but a feature of the materials from which Li-Ion batteries are made! Also, not a single gadget can put a Li-Ion battery in absolute 0, as it turns off much earlier, with the exception of those batteries that are connected directly to the consumer, for example, a screwdriver or just a light bulb!
