A lot of friends are complaining: "idle one or two months of batteries, then even charge not into the electricity, how is it?"

The new battery just bought isn't enough electricity What's going on?

The first thing to make clear is:? Do not assume that all the original is no problem, the original machine how will there be a problem, the original charger how will the problem, the original battery, how can there be problems?

When I ask this question, there are a lot of ridiculous ideas left and right. Most people, such preconceived ideas, cause the maintenance staff to misjudge or find the problem.

At present, the most widely used rechargeable batteries are batteries, Ni Cr Ni MH batteries and Li ion batteries, and the problems that people pay attention to are not charged into batteries, which are mostly aimed at these types.

If the battery is not charged, it should be analyzed in several ways:

The machine itself has problems

External charger problem

Battery itself

First, the method of judging machine problems

1., first of all, in the case of conditional change for the same type of specifications and can use the battery into the machine, if the machine can charge the battery and discharge, indicating that the machine is normal.

If the machine does not charge the battery, repair the machine.

2. can use the external power supply or adjustable power supply to the machine to remove the battery charge and discharge, if can normal charge and discharge, the machine fault (this method only for non intelligent battery).

For the use of too short batteries, first check whether the machine output voltage is in the factory required voltage range, the machine output voltage is not normal, may cause the battery to be dissatisfied with electricity, then overhaul the machine. The output voltage is normal, then refer to the above two to test again.

If the machine can only use batteries instead of charging the battery, the battery can be removed from the machine and placed on another normal charging discharge machine to test whether it can be charged or discharged If the battery can be charged and discharged, the charging circuit of the machine is defective. Or refer to the third test method.

Two, the external charger problem.

For the machine can not charge the battery, you can configure the external charger separately to charge and discharge the battery, how to determine if there is a problem charger?

1. change the charger in the same model and specification to the battery under any conditions. If the charge and discharge can be normal, the charger will be maintained.

2. charging and discharging the normal battery with the charger to be detected. If the charger can charge and discharge the battery properly, the charger is normal, otherwise the charger will be repaired.

3. measuring whether the charger output voltage is within the range indicated on the label, if not normal, then repair the charger.

Three, battery problems

First of all, take out your battery to see if there is a bulging phenomenon, metal contact position is not rusty, if the battery is not normal bulging, indicating that the battery core problems;? Or that the battery life cycle has reached; or the battery protection, circuit board failure. Please do not continue to use the vast numbers of consumers, so as to avoid explosion, causing damage to human health and property! If it is a new battery, do not continue to use, immediately buy the place where you want to replace the battery. If the shelf life is reached, please issue the battery to hazardous waste. If the metal contact of students caused by poor contact, do not charge into the electricity, or dirty battery electrode contact, the contact resistance is too large due to excessive pressure drop when charging the host that has full stop charging; you can use alcohol or water washing plate will rust clean, then wipe clean with a heavy metal the cloth, the machine charge can be reloaded.

Secondly, the battery can be replaced by a battery that can be charged and discharged normally. The battery can be charged and discharged normally after the battery can not be charged and discharged.

If it is damaged or weld line protection etc., need to take the product manufacturers warranty, consumers do not disassemble the battery to avoid battery in the demolition process within a short circuit caused by battery explosion!

Battery zero voltage reason:

1., long-term storage, not used, no additional electricity, the use of self discharge in the form of power consumption, so that the voltage is zero. The capacity loss is irreversible if the power is not added for a long time.

2., the battery zero voltage, or the battery itself is substandard products, the factory did not pass the test. Either the machine is short circuited and the battery is damaged.

3., the internal electronic components, protection circuit abnormalities.

4. all or several electrical cores, zero voltages, or combinations of cells with zero voltage batteries.

5. to come to an end, because of the long-term use, run out of capacity, voltage drop to zero.

We analyze the above zero voltage reason in detail:

1., long-term storage, not used, not to add electricity, you may protect the chip through the zero voltage signal conduction to the battery, thereby turning off the MOSFET, so that the battery can not be charged.

Therefore, we generally require every three months or so, the battery to do a charge and discharge, that is, avoid long-term storage, resulting in zero battery voltage sleep protection, resulting in electricity can not be charged.

There is a battery is full of electricity, is kept in the machine while the machine shut down, there may be part of the circuit on power consumption, such as clock chip, shutdown will not stop working, it will burn the battery, the battery also caused zero voltage, no electric charge, the best way is not battery when in use, is removed from the machine, stored in a dry environment, insulation, and regular replacement of the battery power.

2. charging equipment fault, no output voltage. In this case, you just need to charge the battery to another charger of the same type. Inappropriate charging environment, charger and rechargeable batteries have their own working environment, crossed the two of any of the restrictions, whether high or low temperatures will make charging impossible.

To solve the problem that the battery does not enter the power, there is no diagnosis and treatment. The order is the first diagnosis after the external cause, because the charging method problems as long as correct on the line, and the internal need battery battery testing equipment to the professional knowledge and the correct conclusion, solve in his absence, you can get professional repair outlets for maintenance.
