Battery vulcanization means that in lead-acid batteries, due to excessive and dense lead sulfate attached to the electrode plate, the pores on the electrode plate are blocked, and the active material on the electrode plate is separated from the electrolyte, resulting in battery failure. A phenomenon in which the internal resistance increases and the capacitance decreases. This phenomenon only appears on lead-acid batteries, other types of batteries do not exist. Battery vulcanization is the main form of damage to car batteries, which generally accounts for more than 80% of the damage. But battery vulcanization is solved by science and technology. Daqin Energy Technology battery repair fluid and battery repair system can perfectly solve the battery vulcanization problem.
When the battery is vulcanized, its capacity will drop a lot. For example, a normal battery of 60Ah may actually only have a capacity of 40Ah. After this battery is fully charged, it is normal to measure its voltage, but when it is in use, the battery power drops quickly. Repeatedly start the engine several times, it may run out of electricity, and the voltage will drop a lot; if it is used on a battery car, ride In addition, when the battery is charged, the voltage rises quickly, but the density of the electrolyte increases very slowly, and the temperature of the battery also rises, and bubbles will be generated. It may even swell and bulge.
The main cause of battery vulcanization is excessive battery discharge. The battery on the car is a start-up lead-acid battery, which is characterized by shallow charging and shallow discharge, and it is best to always be in a fully charged state. If you discharge too much at one time, too much lead sulfate will be produced and deposited on the electrode plate, resulting in the vulcanization of the electrode plate. Experiments have proved that if the battery is completely discharged, it can only be recharged to 80% of the rated capacity at most, so over-discharge is the biggest enemy of the battery. In use, repeatedly turning on the starter, listening to high-power audio for a long time when shutting down, using too much on-board electrical equipment, etc., will cause excessive discharge of the battery. In addition, if the battery is used for too long, the lead sulfate accumulated for a long time will also cause the battery to vulcanize.
If the battery has been used for more than three years, there is no need to repair it even if it is vulcanized. If the battery is used for a short time, we can repair it by desulfurization and charging. The specific method is to pour out all the electrolyte in the battery, then add distilled water, and charge it with a small current for a long time. This process is repeated two to three times, and finally the density of the electrolyte is adjusted to a suitable value, so that the battery can be The capacity is restored to about 80%, and it can be used for a period of time.
