Use a syringe to inject distilled water into each hole.If you add a 1.28 standard electrolyte, the board may burn out because of its high acid solubility.For example, when we eat hot pot, why do we eat more and more salty?In other words, when the water evaporates, the salt will not evaporate through steam.Similarly, the acid in the battery will not evaporate.What is lacking is water.So we only need to add about 20-30 ml of distilled water to each small hole. After filling up, let the battery rest for half an hour, so that the sponge around the tray can fully receive moisture.
Then use electricity to block the discharge and discharge all the electricity in the battery. If there is no resistance, it may be replaced by a 12v bulb, such as motorcycle headlights, and car turning signals may be possible. Only they can release the consequences.
How to judge that the battery is about to run out of power, the resistance discharge of the cement at the beginning is hot, and gradually it is not hot.At this time, the battery was also out of power.In the case of light bulbs, it is also direct.Only the light is turned on slowly, which symbolizes that the discharge of the battery is over.The discharge time depends on the capacity of the battery to discharge.We may ride on the battery first until it loses energy.This may shorten the discharge time.
After the battery is discharged, the battery may be charged by pulse charging, because pulse charging may effectively eliminate the vulcanization of the board and increase the capacity of the battery.If you don't have it, you might replace it with a car. (Charging the battery) Take pulse charging as an example. After charging is achieved, a syringe is used to extract excess water from each hole.There are 6 holes in total, which are realized step by step.Close the lid and you may load the car.Lithium iron phosphate batteries in electric vehicles usually have at least ten or more lithium iron phosphate batteries in series, and are equipped with battery maintenance boards.They are completely different from lead-acid batteries (the number is small, and the individual boards are not maintained).If there is a failure, the non-skilled personnel will be helpless to solve it individually.
