What should I do if the electronic scale can t be charged? What happens if the electronic scale is n

Yours is that the vulcanization of the lead-acid battery inside the electronic scale is too serious (some even buy it and use it once and can't charge it, some have a 2 weeks, some have 2-3 months, the better the quality of the lead-acid battery, the slower the vulcanization passivation), resulting in a small capacity, short battery life, days, hours, minutes, and even seconds or 0 seconds (0 seconds, the battery at this time is equal to the open circuit state, which is equal to the non-existent).

Principle of sulfide passivation: lead sulfide is formed after the lead-acid battery is discharged, and after the lead sulfate is gradually and slowly sulfed (crystallized salt), it does not participate in the charging reaction, resulting in a decrease in the total capacity of the battery.

For example, a 4ah lead-acid battery is completely idle, the remaining power is 25% (1ah), and the power deficit is 100%-25%=75% (3ah), and the 3ah of the power-deficient part is gradually vulcanized with lead sulfate, and over time, the power-deficient part is after a period of time. After some time. After some time.

1ah...Finally, 0ah, at this time, the total capacity of the battery is 1ah. With the addition of self-discharge, the true total capacity will be less than 1ah.

This is also the reason why lead-acid batteries should be stored on a full charge.

Here's the professional analysis:

First of all, determine whether it is a lead-acid battery problem or a charging circuit problem.

1. Judge the problem of the charging circuit, if the electric scale can be turned on when plugged in, it means that the charging circuit is good, and the lead-acid battery is broken (the battery is open) or the internal circuit is broken;

2. If you plug in the electronic scale can be turned on, the charging part is good, but unplug the charging cable, wait for a short period of time (it can be 0 seconds, a few seconds, a few minutes or a few days) the electronic scale will be out of power, and the electronic scale will send out a chirping underpower alarm, indicating that the lead-acid battery is not stored and cannot be charged, and the lead-acid battery needs to be replaced, or repaired with a lead-acid 4V battery repair instrument.

In addition, the decay of the plates of lead-acid batteries cannot be repaired by vulcanization.

3 solutions:

1. Buy a 4V repair instrument for lead-acid battery to repair the battery separately, open the cover of the battery before repairing, add 1 ml of deionized water to each hole, and after standing for 1 hour, repair it with a lead-acid battery pulse repair instrument. Disadvantages: repair may not have any effect, the success rate is less than 20%, the repaired battery, every once in a while (long 2 months, short or a few days) will not store power, it will be repaired again;

2. Add "lead-acid battery repair liquid" to the lead-acid battery, the repair success rate is less than 10%, and it must be repaired with the assistance of a repair instrument at the beginning to have an effect, and there is almost no effect without a repair instrument, and it needs to be repaired with a repair instrument every once in a while, which is troublesome;

3. Directly buy a treasure "heavy shield power electronic scale lithium battery", which can simulate the lithium battery of lead-acid work, with a discharge efficiency of 99% (different from the discharge efficiency of the general electronic scale lithium battery is only 30%), ultra-long battery life and standby, fully adapted to the 4V electronic scale system, can be plugged in for 24 hours for a long time, does not hurt the battery at all, and uses it really worry-free, works for more than 5 years, and completely solves the problem.

Let's change the transformer, sometimes the transformer voltage is normal but there is no current. If it still doesn't work, then you disconnect the battery to measure the no-load voltage, which should be about 6V normally. If the voltage is also normal, the battery is broken.

Electronic scales are generally not put on batteries, first of all, understand whether your electronic scale is put on the battery or charged, if it is charged, you need to open it to see if the line is broken, if it is a battery, just replace the battery.

The general electronic scale uses a 6V battery, and you can only replace this battery. If you don't use a battery, you can connect an external DC output 6V power supply.

Check whether the power supply voltage is normal, whether the charger power supply cable is broken and broken, whether the charger is damaged inside, if there is no problem with the charger, check whether the electronic scale itself is connected and broken, and whether the battery is damaged.

The electronic said that I just bought it for a year, which belongs to the warranty period, and it may be a charger problem, you can borrow a charger to try it, if it is still a battery problem.

It may be a problem with the battery, find a battery and try it.

Hello, 1 battery does not store power, you need to replace it with a new battery.

Ask about the new battery.

There is no indicator light or charging symbol when charging, you can try a few more sockets, if there is still none, it can be determined that it is the fault of the charger or charging cable.

Asking questions can be turned on and used.

If you have a problem with the motherboard, find a repair point for professional maintenance for overhaul.

Hello, electronic scales generally use lead-acid batteries, and the charging time is 8-12 hours, so you need to charge enough time. If it is fully charged, it means that the battery is broken, if it cannot be charged, and there is a charging indicator, then the charger is broken, and the voltage is too low. You need to use the original charger or the same voltage to charge it.

Summary. First of all, whether it is a lead-acid battery problem, or a charging circuit problem.

1. Judge the charging circuit problem, if the electric electronic scale can be turned on, it means that the charging circuit is good, and the lead-acid battery is broken or the internal circuit is broken;

2. If the electronic scale can be turned on if plugged in, the charging part is good, but unplug the charging cable, and the electronic scale will be out of power after a short period of time, which means that the lead-acid battery is not stored and cannot be charged, and the lead-acid battery needs to be replaced, or repaired with a lead-acid 4V battery repair instrument.

The human body electronic scale can't be charged, what's the matter?

Kiss! Hello <>

First of all, whether it is a lead-acid battery problem, or a charging circuit problem. 1. Judge the charging circuit problem, if the electric electronic scale can be turned on, it means that the charging circuit is good, and the lead-acid battery is broken or the internal circuit is broken; 2. If the electronic scale can be turned on if plugged in, the charging part is good, but unplug the charging cable, and the electronic scale will be out of power after a short period of time, which means that the lead-acid battery is not stored and cannot be charged, and the lead-acid battery needs to be replaced, or repaired with a lead-acid 4V battery repair instrument.

1. Battery problems.

It could be a problem with the scale battery itself. If it is not good, it means that the battery needs to be replaced. The battery has a certain lifespan. A normal electronic bench scale can only be used for a few hours or a day on a single night. One pound represents the aging state of the battery.

Replace the battery in a timely manner. Some new electronic bench scales use lithium batteries, and the probability of lithium batteries being broken is much smaller. If it is a lithium battery, you should contact the after-sales department of the manufacturer in time.

How to judge the battery itself: If your electronic scale is charged normally for one night and can only be used for a few hours or a day, it means that the battery is aging and can be replaced with a new one.

2.There is a problem with the charging cable or charger.

Because of the charging cable or charger of the electronic scale, the battery of the electronic scale cannot be charged, and it is enough to replace the charging cable and charger with a new one. Try another charger. Okay, the battery is fine.

If there is no indicator light or charging symbol when charging, you can try a few more sockets, or if there is none, it can basically be determined that it is a problem with the charger or charging cable.

3.Problems with the motherboard.

The charger and battery are not included, and it is estimated that it is the motherboard of the electronic bench scale. If there is a problem with the motherboard, the battery of the electronic bench scale will not be charged. Simply replace the main board of the electronic bench scale. Some electronic bench scales do not have these inside.

If a transformer is installed, a power cord is used for charging, so this kind of charging cable is built-in and soldered to the motherboard, and the problem with the motherboard will naturally lead to the inability to charge.

4.Internal wiring issues.

Problems with the scale's internal circuitry can also cause the scale's battery to fail to charge. In this case, it is only necessary to check the internal circuit and replace or repair the corresponding circuit. Some cheap electronic scales wobble during transportation, which may cause the battery line or other wiring to wobble.

There are 5 solutions to the electronic scale if it cannot be charged: 1. Determine whether the battery needs to be replaced; 2. Check whether the power supply has voltage and whether the power cord is damaged; 3. Judge whether the fuse is burned out; 4. Eliminate the above reasons, it may be a circuit fault and need to be repaired; 5. The electronic scale must be charged every 3 months if it is not used for a long time. Ben was netizen.

Summary. Dear, hello, I am glad to answer for you what is going on with the human electronic scale not being charged; 1. First of all, judge the service life of the battery to see whether it has aged and cannot be used. 2. Check whether the AC power supply has voltage, check whether there is a problem with the power socket, or whether the power cord is damaged.

3. Elimination, the transformer is broken, change the transformer and then test, if the transformer fuse is normal, the AC output of the transformer is measured, 9V is normal, and the rectifier and voltage stabilization circuit on the circuit is faulty. In the case of not using the scale for a long time, the battery must be recharged every 3 months to protect the battery. 4. The electronic scale will have a low-voltage alarm light when there is no power, if there are multiple alarms, it is likely to be damaged because of a serious lack of power.

You'll have to get a new battery. I hope mine can help you

If you have just bought it for a short time, you can directly find the merchant to repair and deal with the socks, I hope I can help you

And your phone can't charge a reason.

The electronic scale is not durable and cannot be charged, and it can be easily replaced with a lithium battery in case of emergency, teaching you to repair the electronic scale.

The reason why the scale cannot be charged may be a problem with the battery, a problem with the charging cable or charger, or a problem with the motherboard.

1. Battery problems.

The battery has a certain service life, and the normal electronic scale can be used for a few hours or even a day when charged overnight, which also represents a state of aging and needs to replace the battery in time. Some new electronic scales use lithium batteries, the probability of lithium battery damage is much smaller, if it is a lithium battery, you must contact the manufacturer's after-sales department in time.

2. Problems with the charging cable or charger.

Sometimes the charging cable or charger of the electronic scale will also cause its battery to not be charged, change a charger to see, if it is good, it means that the battery is no problem. If there is no indicator light or charging symbol when charging, you can try a few more sockets, and if there is still none, it can basically be determined that it is the fault of the charger or charging cable.

3. Problems with the motherboard.

If there is no problem with the above, it may be a problem with the motherboard of the electronic scale, once this problem occurs, it will also cause the battery of the electronic scale to be charged, and the motherboard of the electronic scale can be replaced. Some electronic scales do not have those built-in transformers, and they also have to be charged with a power cord, so this kind of charging cable is built-in and will be directly welded to the motherboard, so the problem of the motherboard will naturally lead to the failure to charge.

Tips for choosing an electronic scale

1. Select according to the shape of the scale.

One is square and the other is round, and many friends often don't care when choosing. But in fact, the shape will also affect the practicality, we know that the area of the square is much larger than the area of the circle under the same size. Therefore, when the human body stands on the scale, the square health scale is more comfortable, stable, and has a wider standing space than the round one, and maintaining a relatively stable state can make the weighing effect more accurate.

2. See whether the single circle displayed by the electronic scale is accurate.

The purpose of using the scale is to be able to know our weight more accurately at any time, so the accuracy of the scale is related to whether the measured weight is accurate or not. Cheap health scales tend to be accurate to the whole number, while good brand scales are generally accurate to the decimal place. We must also take into account the load-bearing range of the health scale when purchasing, the maximum load-bearing range of the current better quality weight scale can reach more than 150kg, which can basically meet all the people.
