How to charge and use lithium ion battery: charging rules, discharge, operation. What current and voltage charge lithium ion batteries?
In this article we will tell about how to properly charge lithium-ion batteries type 18650 for the phone, laptop, tablet and smartphone, as well as what rules of operation of the batteries must be observed.

So, let's start with the fact that lithium-ion accumulators themselves are not so practical, if you compare them with nickel-metal-hybrid fellows, which have much more service life, but at the same time we give up the tank and at a price are more expensive. But almost all the electronics work on lithium-ion batteries, in connection with which the question arises, how to charge them?
Lithium-ion batteries 18650 for phone
Quite a frequent problem with phones is precisely in the wear of the lithium-ion battery. Thus, as the battery, the battery begins to keep the charge, and the phone has to be very often set on recharging. The reason for the rapid wear of the lithium-ion battery lies not only in the fact that the phone is very actively used every day, but also in the fact that its operating owners are sometimes not quite careful, and some do not comply with any rules for using this type of batteries. .
How to find out that the battery came caught and already unfastened to work?
FirstlyWhen the battery is already caught enough, it will begin to malfunction and the accumulated capacity that received in the charging process.
SecondlyThe phone with a worn battery will not work with such a period that is declared by the manufacturer.
ThirdlyWhen the battery is completely worn out, it begins to change the appearance, that is, external deformations appear, something like blinking or bubbleness in certain areas.
So, let's list the most common problems with the phone, if it has a worn lithium-ion battery:
- After a 12-hour charging of the smartphone, he served just an hour or two, and then periodically rebooted and gave failures in work.
- He took off the phone with charging, it was 100%, but after 10-35 minutes of use, it rebooted, and then the percentage of charging was only 1%.
- The back lid of the smartphone has become uneven, and before it was flat.
- The smartphone is constantly rebooted, and the percentage of charge with each reboot changes, there were 87% on the first load, and the second was 64%.
How to charge lithium-ion batteries for your phone?
Note that if your battery on the phone is no longer suitable for use, it will not charge the phone charging. Thus, such "dead" The battery can be charged only with direct contact.
Therefore for "Duffen" Batteries that can still be done, or so to speak can be revived, special chargers with two ends are used. Similar chargers are usually called "Frog".
It is worth notingthat charger "Frog" It is versatile, in connection with which it can be charged with any battery for a phone of any brand. But again, the work of such a device depends on its quality, brand, characteristics and dimensions. Nevertheless, let's figure it out how to charge "Duffle"batteries using a similar device:
- First of all, you need to remove the battery from your phone, after turning off the phone.
- Then you need to take a charger "Frog" And click on the end of the battery holder to secure the position of the battery.
- After that, you need to send two burrs to the point plus to the plus and minus to minus.
- When everything is done, and the contacts of the bumbaction with the battery contact them hard, then you can insert a charger into a 220b network.
- If your battery is discharged and have less than 95% of the charge, then the red indicator will burn on the charger, if the green indicator is lit, this means that the battery has more than 95% of the charge.
Lithium-ion batteries 18650 for laptop
As a rule, similar batteries on laptops have much large dimensions than batteries from cell phones. Therefore, a completely different approach is provided to charging such batteries. In case the battery on your laptop has become unusable and does not eat charging at all, you can safely buy a new one.
How to find out that the battery came caught and already unfastened to work?
So let's list the most common problems with the laptop if it is worth a worn lithium-ion battery:
- After a 12-hour charging of the laptop, he did not serve even ten minutes, as a result, suddenly turned off, and you did not even have time to complete the working session.
- He took off the laptop with charging, it was 100% charge, but after 20 minutes not such an active use of the laptop, he lost half percent of the charge.
- The laptop constantly requests permission to check and defragment the disk, which sometimes lasts up to an hour, and the reason for this is that due to such a worn battery, the laptop incorrectly completes the working session.
- It is impossible to work with a laptop if you do not connect it to the charger. Thus, with the second absence of a laptop battery nutrition, it immediately stops working and the working session is completed.
How to charge lithium-ion batteries for a laptop?
As mentioned earlier, if the laptop battery became at all "Dahle",and for a term lasting for more than 5-8 years, it undoubtedly needs to be changed, that is, to buy a new one. Of course, there is a variant of the dismissal battery to replace batteries inside, but after such a procedure is lost the same type of this battery.
Thus, if your battery is already at all "I died"and it does not keep charging at least 10-20 minutes, then you need to buy a new one, otherwise you will soon make it on the purchase of a new hard disk, which is more expensive.
Lithium-ion batteries 18650 for tablet
It is worth notingThat on tablets, or on the same PDAs cost 2-3 times more batteries, both in length and wide, and at the same time they have a virtually similar container.
But the problem with the wear of the batteries and bring them over time to unsuitability here is also often affected. After all, at the beginning of the article, we said that it was the lithium-ion batteries that are very whimsally in use, and they need almost special care for them. Now the question arises, and how to distinguish a worn battery on a tablet from a working suitable battery? We will talk about it further.
How to find out what the battery is worn out?
So, let's list the most common problems with the tablet if it is worth a worn lithium-ion battery:
- After a 12-hour charging of the tablet, he served just an hour or two, and then periodically rebooted and gave malfunctions.
- He took off the tablet with charging, it was 100%, but after 10-35 minutes of use, it rebooted, and then the percentage of charging was only 1%.
- The back cover of the tablet has become uneven, and before it was flat.
- The tablet is constantly rebooted, and the percentage of charge with each reboot changes, 87% was on the first load, and 64% became on the second.
How to charge lithium-ion batteries for the tablet?
In this case, as with the battery for the phone, you need to take into account that if your battery on the tablet is not at all suitable at all, it will not charge from charging the tablet. Thus, such "dead" The battery from the tablet can be charged only with direct interaction of currents with battery contacts.
It is worth noting, what "Frog" It is not only suitable for charging the batteries from phones, but also from tablets, since the capacity of two batteries is almost similar and not quite large.
- First of all, you need to remove the cover from the tablet, and after removing the battery, but before it is pre-disabling the tablet itself with the button «Power. "
- Then you need to take a charger "Frog" And click on the end of the battery holder to secure the position of the battery.
- After that, you need to send two burrs to the point plus to the plus and minus to minus.
- When everything is done, and the contacts of the bumbaction with the battery contact them hard, then you can insert a charger into a 220b network.
- If your battery is discharged and have less than 95% of the charge, then the red indicator will burn on the charger, if the green indicator is lit, this means that the battery has more than 95% of the charge.
What rules must be adhered to when using lithium-ion batteries for phone, tablet and laptop?
So, in this article we also collected 5 necessary rules that need to adhere to any batteries, whether it is a telephone, laptop, smartphone or tablet.
Always keep the battery charge at the average level
In no case can not be a battery to the end, since lithium-ion batteries do not have such an opportunity as "Memory effect".Thus, it can be said that if you planted a lithium-ion battery to the end, then it is two, or even three times it will reduce your potential and possible chargeable container.
Tell the battery once a month
It is worth noting that if the battery is always charged to a maximum of or 100%, it will not live as long as I would like. Therefore, it is necessary to carry out some kind of prevention to increase the battery life, for which it is necessary to discharge it to the end, but in the short term.
Never hold 100% battery charge for a long time
Note that the full charge of the battery also strongly affects how much this battery serves you. Therefore, it is better and most of all, it will last if the percentage of charge will be held stably in the area of \u200b\u200b50-60%, and the recommended temperature conditions for the battery must be about 15 ° C.
Use only high-quality batteries of original production.
Many buyers complain that the batteries serve little and they often buy them very often. The problem of such buyers is that they are trying to save on the brand, and therefore on quality, in the end, they get a cheap battery of poor quality, which will last a maximum of the month.
Do not allow the lithium-ion battery overheating
The most dangerous enemy for lithium-ion batteries is an ultrahigh and very low temperature. Thus, never hold the battery under -40 ° C to + 50 ° C, as it extremely strongly affects their durability. Try so that the phone does not fall under the influence of direct sunlight, as they heat the battery in the phone very much, especially if you have black.
Well, on this we probably finish our article!
