How much to charge the battery with a frog. How to charge batteries "frog
Batteries with more than two contacts can be charged using the described device, but to do this you will need to disassemble the battery and connect the charge to it, bypassing the controller.
Following from the above, it can be understood that the Frog is a universal charger, very useful in case of breakdown of other power sources, small batteries, as well as the inability to charge gadgets in the usual way, which happens quite often. At the moment, manufacturers offer all new devices equipped with a USB-port and LCD-display, which greatly simplifies their use.
The advantages of the device:
- The presence of USB-port that allows you to charge most devices.
- Easy to use.
- With frequent use, relative fragility.
- A long process of charging capacitive batteries.
"Frog" - the best option for a backup source of energy
Despite the few drawbacks, the Frog is a charger, the price of which is very diverse (from 60 to 650 rubles), is quite a useful thing in the economy, if only because it is able to literally revive no signs of the life of a battery of phones and cameras . But keep in mind that you need to use this device as needed. Recharging too often with the help of the “Frog” can lead to a rapid depletion of the battery and, accordingly, its failure. Paradoxically, but it is.
Despite the fact that mainly these Chinese-made chargers, you should not neglect such products. On the modern market, you can find universal and unique auxiliary devices that can significantly facilitate our lives and give a second chance to the details, which in another case would certainly have fallen into the garbage. Therefore, it makes sense to have at least some idea of how to use the Frog device for normal charging of a phone battery.
Modern technology amazes and impresses with its diversity. For example, there are many types of devices for charging various devices. In this article we will discuss such chargers, which are colloquially called "frogs". The frog is very simple and easy to operate. It is plugged into a standard outlet at a voltage of 220 volts.
The frog is a universal charger that fits all batteries of any kind. mobile phones . Good frog for others lithium batteries For example, from cameras, PDAs and other small-sized equipment.
The charger is a small box that looks like a frog with a plug for the outlet. From the body are two antennae - to connect and to charge.
There is nothing difficult in how to charge the battery with a frog. To recharge your phone using this device, you need to perform several not very complicated actions.
How to charge a frog: instruction
- If you studied this device, read the enclosed instructions on how to charge the phone with a frog, then you probably know that you first need to remove the battery from the phone, but before that you must turn it off.
- Next, click on the frog clothespin. This is necessary in order to open the device.
- Now try inserting a battery into the device so that the two terminals match. If your charger has four terminals, then you need to use two, which are located on the side.
- Then click on the TE button (it is usually on the left). If the CON LED lights up in green, this indicates that you managed to connect everything correctly. If it does not catch fire, then try reconnecting the terminals.
- Now, if you have already checked the connection, and the CON LED does not light up, it may well be that the battery was completely discharged, which is called “zero”. In this case, your battery charger should be inserted into the network for about five minutes. After that, check if the CON indicator we need now lights up. Lit up - it means everything is in order. If again, nothing happened, check whether there is voltage in the network, as well as the condition of the battery itself.
- Now turn on the network. Is the CH indicator lit or flashing? If yes, then everything is fine.
- The battery will be charged when the left FUL indicator on the charger lights up.
As you can see, there is nothing particularly difficult in this matter. Now you know how to charge through the frog.
If you lose your native charger from a mobile phone or smartphone, inexpensive universal charging for 3.7 volt lithium batteries, so-called frogs (or frogs), come to the rescue. They have adjustable contacts, which directly connects the battery, previously pulled out of the phone. Of course, this creates some inconvenience (you need to constantly remove the lid, time gets lost), but sometimes this is the only way out when charging from rare chinese phone lost
Instructions for using the charger
The frog charger is designed to charge Li-Ion batteries, which are used in cell phones, GPS receivers and cameras. It works on 110-220 V mains. Output voltage 4.2 volts, current 200 mA. The charge occurs automatically and is controlled by the microcircuit, and it automatically turns off when it reaches the required level. Standard charge time is 1.5 hours.
It is necessary to clamp the battery in the frog so that the contacts charger were on terminals + and - battery. If the battery is 3 or 4 contacts - usually you need to use 2 extreme. If the connection polarity is correct, then when the TE button (left) is pressed, the first green CON LED lights up. If it is not lit - press the right CO button (reverse polarity) and repeat pressing the first button. On some frogs, CON can be lit when connected without pressing a button - also the correct polarity. Also, there are already models that will automatically determine the polarity. Accordingly, there is no right-handed reversal button.
If everything is fine - CON is lit green, turn on the 220V outlet. The PW lights up and the CH (charge) charge starts to burn or blink. At the end of the charge, the right FUL LED (full) lights up. If the CON does not light up at all, the battery may have gone to zero. Then connect arbitrarily in any polarity and stick it into the network for 5 minutes (not for long - it's not scary). If the CH flashes, then the charge goes and everything is correct, otherwise change the polarity with the right button and see how the CH will behave then. If the PW and FUL are immediately lit, then most likely the battery in the frog is not contacted (this is how the LED is lit without a battery at all) - slide it towards the contacts.
Instructions for repairing memory "frog"
As for the completely non-working memory - then just look for the burnt part. But sometimes there are poor-quality chargers, when, when connected to a battery frog, the charge current is less than that indicated. Not 200 ± 50 mA, but several times less. Thus, the battery is simply undercharged. As the charging current at the output decreases, the final voltage on the “fully charged” battery also decreases. From here and a small resource of the accumulator at installation in phone. When the light alarm of the charger signaled the end of the charge, the battery voltage was only 3.9V. Why it happens? Most likely the case in the variation of parameters. A small deviation in the resistor values leads to a change in the overall characteristics of the device.
The schematic diagram of the memory frog
Replacing the constant resistors R14 and R15 (the numbering of parts on the diagram corresponds to the numbering of parts on printed circuit board ) for multi-turn trimmer resistor brand SP3-39A nominal 10 Kom, it is possible to accurately set the output current. After the replacement, the current was set at 250 mA, which roughly corresponds to the specified parameter on the charger case. You can, of course, charge the charging current with a trimmer at will and another one. When the device’s light alarm is turned on, announcing the end of charge, the charging current is reduced to 70 mA, and the battery voltage is set at 4.15V. The process of full charging lasts about two hours, that is, as when charging in the device with a native charger. Full version instructions download on the forum.
After analyzing several charts of memory, Frog, stopped at one of them. I decided to make it as a prefix for charging NOKIA (I think many have them, and I have a few of them lying around) to charge the Li-ion 18650 battery. In the charger from NOKIA, the output from the transformer is almost 7V, which should be enough for the console.
For the battery itself, you will need a battery compartment, for mounting it on the side of the case. On the cover - the output of four LEDs and a microtampler. In the meantime, a signet has been developed on the CMD and simple radio elements, with installation on top of the board. Download it.
Signet that is attached, already mirrored, immediately send to print. The photo shows just the location of the elements, as it should be.
Then I soldered a separate memory handkerchief, tested it - it works great! With the specified details at the output of the charger 4.2V. Put the used battery for charging - the charge rises. Chip LM358 put a soldered, shot for good from where. BP used with output 6V 0.45A.

How to use the charge "frog".
The universal frog charger (“frog”) is designed to charge lithium Li-Ion batteries with a capacity of up to 2000 mAh and voltages from 3.5 to 4.8 V, which are used in most cell phones, PDAs, GPS receivers and cameras.
Powered by 110-220 volts. The output voltage is 4.25 volts, the current is 200 mA.
The charge occurs automatically and is controlled by a microchip. The charge automatically shuts off when the required level is reached. The standard charge cycle (time) is 1.5 hours.
It is necessary to clamp the battery in a frog so that the contacts of the charger are located on the + and - terminals of the battery. If the battery is 3 or 4 contacts - usually used 2 extreme.
If the connection polarity is correct, then when the TE button (left) is pressed, the first green CON LED lights up. If it is not lit - press the right CO button (reverse polarity) and repeat pressing the first button. On some frogs, CON can be lit when connected without pressing a button - also the correct polarity. Also, there are already models that themselves determine the polarity. Accordingly, there is no right-handed reversal button.
If everything is fine - CON is lit green - turn on the outlet. The PW (power - network) lights up and the CH (charge - charge) starts to burn or blink. At the end of the charge, the right FUL LED (full) lights up.
If the CON does not light up at all, then the battery is probably dead. Then connect arbitrarily in any polarity and stick it into the network for 5 minutes (not for long - it's not scary). If CH (charge - charge) flashes, then the charge goes and everything is correct, otherwise - change the polarity with the right button and see how CH will behave then.
If the PW (network) is immediately lit and FUL (fully charged), then most likely the battery in the frog does not come into contact (it does not burn at all without the battery) - slide it towards the contacts.
Sometimes, in case of a faulty battery (if one element dies), the frog can show full FUL charge even if the normal voltage is far away. It's just that the charge current doesn't go anymore - that's all.
If a cell with a dead battery does not turn on for charging, does not show signs of life at all, then read below.
I must say that if a battery with a nominal voltage of 3.6 volts sits below 3.2 volts, then a mobile phone may not show signs of life at all, even if a standard charger is connected. That is, the controller sees that there is no battery at all and does not include a charge. In this case, the frog is an indispensable thing - turning on the battery for 5 minutes through the frog - you give a boost to the battery, after which it can already be charged in the phone itself.
An additional 3rd contact on the battery is usually a signal from the microcircuit controller (or simply a thermistor) that are inside the battery and do not allow overcharging and overheating - they give a signal to the charger ( cell phone a) limit the current or disconnect the charge altogether. In a frog, such a control does not occur and it is considered worse to charge than the charge that came with your device, so you should not leave the frog for a long time unattended, especially if your battery heats up when charged.
General device information
The frog is a simple device designed to charge cell phone batteries of various models and manufacturers.
In addition, the "toad" can be from cameras and other small-sized equipment.
Outwardly, it looks simple and is a plastic box with a fork on one side and a special clip for contact with the battery on the other side. The design of the "frog" allows you to apply it to batteries with connectors of different sizes due to the movable contact terminals.
Universal adaptation does not require any special technical knowledge or skills. To use a frog, there is no need to think about how to properly insert the battery into it. She herself will determine its polarity.
Varieties of universal charge
To date, several types of devices of this type can be found on sale, designed for lithium batteries of mobile phones and other small-sized equipment that differ in power supply:
- from car cigarette lighter ;
- from USB port ;
- from electrical outlet .
Also universal charging can be automatic and semi-automatic. The main difference in the number of light indicators. There are three automatic machines, and semi-automatic - four. The automatic “frog” will determine the correctness of polarity itself, and for the semi-automatic, additional control of the correctness of the connection will be required using buttons.
How to use the "frog"?
How to use universal device ? The algorithm of its application is simple and the same for all. You can charge the lithium battery of a phone, camera, camera, navigator with a frog, provided that it has the following characteristics:
- capacity not more than 2000 mAh ;
- current 200 mA ;
- output voltage 3.5-4.6 V.
Charge the battery with a frog, if it does not meet these characteristics, it will not work.
First you need to disconnect the battery from technical device . Then it is installed in the "frog" so that the terminals (+ and -) coincide with the contacts of the device. Most charges of this type have up to 4 terminals, but, as a rule, two extreme ones are used.
The next step is to check the polarity if the model is semi-automatic. To do this, press the button Te (it is on the left). If the green light is on, the battery is connected correctly. If the connection is incorrect, use the button for changing the polarity of CO (located on the right), and then the TE again. In the automatic model, the polarity itself is not necessary to determine.
During operation, the PW and CH network indicator will be active, and at the end of the process - FUL indicating that the battery can be used further. After 2.5-5 hours after placing the battery in the device (the time depends on the model of the battery), it can be removed. It is fully charged and ready for use.
Important! The frog is only suitable for charging lithium batteries. Batteries of a different type after trying to restore them to “zhabkoy” will become unsuitable for further use.
What to do in an unusual situation
When using a universal charger, atypical situations may arise, for example, a battery is charged too fast or there is no indicator light.
How to charge the battery of cellular terminals, if no indicator of the working device is lit? In such a situation, it is recommended to press the CO button.
If there are no changes after this, most likely:
- there is an error with the contacts, you need to change the polarity ;
- Battery inoperative ;
- "Frog" broke .
The device will help in a situation when the phone battery is completely sat down and has not been used for a long time. In this case, it should be placed in a frog for 10 minutes, after which it should be charged with a terminal’s own device.
If during operation the device signals 10–15 minutes after connection full charge then it failed. And the FUL indicator, which is active when connected to the network, indicates that the battery is unsuitable.
If both the FUL indicator and the PW indicator light up at the same time, the charger does not contact the battery.[ U ] [ OT ] [ ST ] [ OST ] [ TG ] [ GTU ] id Other Russian Ukrainian Belorussian Polish English Spanish Deutsch Turkish Bulgarian Czech Hungarian Estonian Armenian Kazakh Hebrew Georgian Serbian Croatian Lithuanian Slovak Slovenian Albanian Macedonian Latvian Kyrgyz Mongolian Portuguese Uzbek Korean Romanian Danish Greek Dutch Norwegian Swedish Italian French indonesian id arabic Hindi Bengal Chinese [Azerbaijani ] [bosnian bs ] [tajik ] [Latin ] [Vietnamese ] [Kannada kn ] [Finnish ] [Filipino ] [Irish ] [Icelandic ] [Scottish (Gaelic) gd ] [Japanese ] [Afrikaans ] [Amharic am ] [Catalan ] [ Cebuan ceb ] [Corsican ] [Welsh ] [Esperanto ] [Basque eu ] [Persian ] [Frisian ] [Galician ] [gujarati gu ] [house ] [Hawaiian ] [Hmong hmn ] [Creole (Haiti) ht ] [Igbo ig ] [Javanese ] [Khmer ] [Kurmanji ] [Luxembourg lb ] [Lao ] [Malagasy ] [Maori ] [Malayalam ml ] [Marathi mr ] [Malay ] [Maltese ] [Burmese my ] [Nepali ] [cheva ny ] [punjabi ] [Pashto ] [sindhi sd ] [Sinhala si ] [Samoan ] [shona sn ] [somali ] [sesoto st ] [Sudanese ] [Swahili ] [Tamil ] [Telugu te ] [Thai ] [urdu ] [khosa xh ] [yiddish yi ] [yoruba yo ] [zulu ] [ Tf ]
