What should I do if I use universal charging to confirm that the light is on but the charging light

If the "charging" light is not lit in the early stage of charging, only the "power" and "saturation" indicator lights are on, this phenomenon is mostly caused by poor contact or wrong contact between the battery electrode and the contact electrode, repeat 1, stationary battery: adjust the position of the metal contact according to the spacing of the positive and negative electrodes of the battery, make the contact between the contact sheet and the battery position correct, and keep the contact between the metal contact and the battery electrode good, and insert the lead plug directly into the corresponding jack for the lead battery. 2. Polarity confirmation:

If the red "polarity" warning light is on after the battery is installed, it means that the positive and negative polarity of the battery does not correspond to the contact electrode, and the "switch switch" on the left side of the charger must be toggled to switch the polarity, and the red "polarity" warning light is turned off to indicate that the polarity has been correctly connected. Until the "Charging" red light is on to enter the normal charging state.

Just find a small electrical appliance small bulb small motor WhatsMiner wiring to the charger contacts If it turns on or turns, it means that the charger light is broken, but it can still be charged. Or confirm that the contacts are connected to the battery, charge for about five minutes, and then turn on the battery, if the power level changes, it means that it can be charged.

Check whether the electric board is in good contact with the universal charger. Sometimes you have to stagger a little bit. If it doesn't work again, it may be a universal charge.

It should be that the connection inside is broken, I've encountered it before, just connect it.

It may be that the positive and negative poles of your battery board are not aligned with the universal charging connector.

Yes, the universal rechargeable battery will not flash after it is fully chargedHowever, at this time, the charger still charges the battery with microcurrent, because if the charger has no current output, the current of the battery will flow back, so it is necessary to set a microcurrent to ensure that the current of the battery will not reflow.

Note: NANK charging head C1 is the recent super hot iPhone12 mobile phone fast charging charger, in order to change the traditional charger heavy, large, ugly, and slow charging phenomenon, NANK charging head C1 from the material selection, cutting, shaping, grinding, etc. all the way through more than 60 product grinding processes.

Create a unique thin and compact boutique body, 20W high-power fast charging, compatible with Apple and Android mobile phones.

Fast charging. Its small and thin design is smaller than that of ordinary 5W chargers, and the figure of MINI has been evaluated as "the smallest charger brand" by major science and technology.

No.

If the prompt light is always on, the user needs to check whether the contact connection is wrong, and the contact user can try to load the battery into the mobile phone, and then use the direct flush to see if it can be charged normally, if it can be charged, it means that the universal charge may fail, and it is recommended that the user replace it.

Charging mode. 220V AC DC lithium battery charging, if there is a problem in any link, it will become a battery killer, and it will be serious when it is serious. The charging process of lithium batteries is constant current, constant voltage, and trickle charge.

First of all, constant current charging, that is, when the current is a certain value, the battery voltage gradually rises with the charging process, when the battery voltage is reached, the constant current charging becomes constant voltage charging, that is, the voltage is constant, and the current gradually decreases according to the saturation degree of the cell.

When the current decreases to a certain level, the charger considers the charging to be complete, and then trickles up the battery with a small current. In the circuit design, many universal chargers change the charging cut-off voltage to, that is, when the battery voltage reaches the level, the battery will continue to be charged at a fixed current until the battery voltage reaches the set value.

Then use a fixed current to replenish the battery, and use a fixed resistance resistance to "leak" some current, this current is fixed, plug in the battery, and it will not stop. So the battery is fully charged. Therefore, some friends will feel that the original charger is charged with a universal charger and the battery life is longer.

However, the damage of overcharging to lithium batteries is very serious, and in the long run, the performance of the battery decays quickly. Therefore, friends who have been using universal charging for a long time will find that the battery is swollen and the battery life is not as good as before after a period of time, which is precisely due to the overcharging of the universal charger.

Not necessarily, mainly depending on whether the single circuit of the indicator is bad or multiple circuits

It should not be, one is a detection light, the other is a charging light, if it is not lit, it means that it is not charged.

No. You can change the battery and try whether the battery is bad or the universal charge is broken.

Absolutely, that's what I do.

Check first if it is a circuit problem, if it is a circuit problem, please operate it safely, do not plug it in, there are many reasons why the light is not on, do not try it, safety first, I hope I can help you.

It's time to change the charger Try it with Xinyu hxy.

Try to change to other mobile phones, whether it is a universal charge.

If the charger's indicator light is not on, it means that the charger has a faulty problem, so it can no longer be used.

Electric vehicles are a relatively common means of travel, and the structure of such a means of travel is very simple. The key components of an electric vehicle include the frame, electric motor, battery, and regulator. Most of the regulators will be fixed under the rear seat, and the function of the regulator is to adjust the circuit of the whole car.

Without the regulator, the electric car cannot be driven properly.

The frame is the basis on which all the components of an electric vehicle are fixed. The electric motor is the first of the electric vehicle power, and the electric motor can drive the electric vehicle forward. The battery is a part of an electric vehicle that is used to store electrical energy, and the battery can supply power to the electronic devices of the whole car.

If you don't have a battery, you won't be able to drive an electric car.

The battery is a wearing part that needs to be replaced regularly, and the performance of the battery may continue to deteriorate as the number of charge and discharge times increases. During charging and discharging, the ions in the battery move in the electrolyte, and some ions react chemically with the electrolyte as they move in the electrolyte.

When the headlamp is plugged in and the charger is not bad, what happens if the charger does not light up? I have a headlamp with a different head, and the power suddenly doesn't light up after charging, what's going on?

Hello, it's the lithium battery in the headlamp that has failed. Plug in the charger and the charger will power directly to turn the lights on. The cause of battery failure may be the use of a different charging head (using the original charging head).

Generally, the charging head of the headlamp is volt, and if the 5-volt charging head is used, the battery in the headlamp will be damaged.
