Does electric vehicle battery repair fluid have a certain effect?

The “water loss” of the battery can be repaired by replenishing water. The purpose is to dilute the sulfuric acid with an increased concentration to carry out the electrolysis reaction normally. The water replenishment method is relatively simple, just open the battery cover, you can see that there are six round holes, inject a certain amount of distilled water into each round hole, and then soak for more than 24 hours. Water replenishment can only be supplemented with distilled water. Water with other ingredients, including purified water, cannot be added, because there are various metal molecules in the water of other ingredients, which will easily cause self-discharge and damage the battery after being added to the battery. Expanding all the battery car battery repair fluid does have a certain effect, but the effect is not good after the repair, and it can only be used for a period of time. The repair effect of closed valve-regulated lead-acid batteries within 3 years is very good, because lead-acid batteries will lose water due to charging after 1-2 years of use, and over-discharge will cause the crystallization of lead sulfate layers and lose water. Sulfation is more likely to occur later, resulting in a decrease in capacity. At this time, add a certain amount of distilled water to the closed lead-acid battery, and use a pulse desulfurization equipment with constant current and unlimited pressure to desulfurize the battery. Desulfurization requires a relatively long time, generally 1.5 to 2 times, 0.2C charging time. The battery temperature is maintained at about 45 degrees, and the voltage is greater than 16V for a period of time to achieve the desulfurization effect. The temperature cannot be too high, and cooling measures are needed. The battery used in the battery car is generally a lead-acid non-dimensional battery. The lifespan is calculated based on the full charge and discharge of the battery 300 times. These 300 times are calculated by reducing the battery capacity to 75% of the nominal capacity. This data is very important because The user will not charge the battery when it is only 75% of its capacity, but will charge it when there is really no way to use it. At this time, the battery capacity has dropped to 40% of the nominal capacity, that is, overdischarge has occurred. The vulcanization process begins after the battery is discharged, and obvious vulcanization will appear after 12 hours. Charging in time can remove non-serious vulcanization. Extended information: Battery repair fluid is also called lead-acid storage battery repair fluid, battery activator, battery compatibilizer, etc. It is a solution that can be added to a failed electric vehicle battery to restore the battery's capacity, extend the battery's service life, and improve the performance of the battery. No need to go through a professional repair instrument, simple and easy to operate. As the composition of the repair fluid is different, the repair effect is also different. After adding the battery repair solution, the battery capacity is restored after a full charge and discharge, and the distance can be increased by 5-15 kilometers. After seven times of full charge and discharge, the battery capacity is restored to more than 90%, extending the service life by about one year. After all batteries have reached a certain life limit, various failures and failures will occur. Some failed batteries can be repaired by adding repair fluid, and some are scrapped if the problem is serious. According to the national standard for electric vehicle batteries (JB/T10262-2001), a battery with a capacity lower than 70% of the nominal capacity is a failed battery.
