The common problems in battery repair and the reasons for the ineffective repair of lead-acid battery when the battery plate is vulcanized

Release date:2018-03-21 Author:concord Click:

     

  Zhengzhou conley of electronic power co., LTD., founded in 2000, professional development and production of sales of 2 v, 4 v, 6 v, 12 v four series and maintenance-free lead-acid battery, gel battery and electronic charger, etc. Products are widely used in security alarm system, fire alarm system, building intercom system, elevator emergency evacuation system, emergency lights, antenna, power sprayers, electronic said, children, cartoon gas mould, washing machine, rotary table, parking lock, flashing lights, traffic lights, dc panel, solar energy, wind energy, UPS, EPS, etc for electrical system.

  

  Blob. PNG

  

  Since in 1859, French physicist plante since the invention of lead-acid battery, prolong the service life of the battery is a major topic studied by people, and long-term practice, people use a number of ways to eliminate the battery plate, the zhengzhou conley of electronic to introduce you to lead-acid batteries battery plate vulcanizing, battery repair and common problems in the process of repair is invalid.

  

  Common problems during battery repair

  

  1. During the repair, the voltage was found not to rise, and whether the self-discharge of the battery was serious was checked.

  

  2. If the charging current cannot be decreased during the charging process, and the battery is accompanied by heat, the battery has problems.

  

  3. Use water therapy to repair the battery must wear acid-proof clothes, and wear rubber gloves, so as to prevent sulphate from splashing on the body.

  

  4. Acid cannot be discharged at will.

  

  5. During the repair, the battery shall be temporarily suspended when it is found to be hot.

  

  6. When repairing the battery with additives, you can use ordinary charging, but the effect is slightly worse. Meanwhile, you should pay attention to putting the battery into acid-proof container to prevent the electrolyte from overflow and flow to the equipment and the ground.

  

  7. If the pole is stained with electrolyte, it shall be cleaned carefully, otherwise the pole will break down in the future.

  

  8. The repair time can be determined according to the service time, actual condition and initial capacity of the battery, generally 2 to 7 days.

  

  9, after some battery repair, recovery capacity is obvious, but dynamic performance decline after put into use or use the capacity decay quickly, soon appear there are three main reasons for this: electric load current is bigger; The battery has high internal resistance and large capacity attenuation rate. Therefore, it should be considered to replace the battery.

  

  Battery repair is ineffective

  

  If the battery capacity increased after the repair, or wasn't up to more than 70% of the nominal capacity, it is generally believed to repair is invalid, battery repair invalid reasons are complex, and the cause of the battery, also have the cause of the operation, and use the methods and materials, the battery itself, the main reasons are:

  

  1, the battery positive plate softening, its outstanding performance is: there are black impurities in the electrolyte, if more black impurities, is the positive plate to soften, such cells cannot be repaired, basically can only be scrapped.

  

  2. There is a defect in all the repair methods of the battery: the original state of the positive plate cannot be changed during the repair process, and the positive plate of the electric vehicle battery is prone to problems. We can eliminate all accidental damage: broken roads, hard short circuits, physical damage, etc., but we can't distinguish between vulcanization and positive plate softening failures. As for batteries, it is hard to tell which is the main reason for the decrease in capacity caused by the vulcanization of negative plate and the softening of positive plate. , for example: the capacity of the battery capacity mainly depends on the capacity of positive plate and negative plate of the lower one (this is the ideal situation, in fact, the electrolyte density, the distribution of lead sulfate, size, and so on all have an impact on capacity). If you have a 12V/10Ah battery, at the end of the battery life, the negative electrode will release 5Ah, while the positive electrode will release 7Ah. In most cases, the elimination of vulcanization allows the battery to release 7Ah of electricity. But then there is the problem: with 7Ah of power released, the softening rate of the positive plate will increase, and the capacity of the positive plate will decrease faster. The decline in battery capacity will be accelerated. We will find that many of the restored batteries have no effect. In the other case, a positive plate can emit up to 5Ah of electricity, while a negative plate can emit 7Ah. In this case, because the plate of the original quality problems, after repair battery, or only 5 ah battery, the individual is plate of the battery, the serious problem of pulse current, due to the more loose structure, resulting in decreased capacity, battery repair is null and void.
