What is the formation of waste lead-acid battery?

In life, we often come into contact with lead-acid batteries, and what we all know is that improper use of lead-acid batteries will make lead-acid batteries early become waste lead-acid batteries, but this time will always be extended if we can fully maintain it in our daily life. First of all, we need to be clear about what caused the battery to become a waste lead-acid battery:

1, lead acid battery itself quality and manufacturing quality problems;

2, the charging mode of the charging equipment(charger) supporting the lead acid battery does not match the battery;

If the lead-acid battery is not matched with the charging device(charger) when charging, the charging voltage is too high, and the long charging time will lead to the rapid decomposition of water in the electrolyte(aqueous sulfuric acid solution), and the resulting hydrogen and oxygen can not be completely compounded within the battery., Therefore, the loss of water from the battery is accelerated, and the corrosion of the plate is increased, and the aging of the battery is accelerated to become a waste lead-acid battery.

3, the user of lead-acid battery can not use and maintain the battery according to the maintenance requirements of the battery;

If excessive use of lead-acid batteries results in overdraft of electricity, degradation of the conductive bridge between lead dioxide particles on the positive plate, and loss of contact between some lead dioxide particles and contact between lead dioxide particles and the grid. This means that isolated particles no longer participate in electrochemical reactions, the mechanical strength of the active material decreases, and the possibility of falling off increases. Overuse(over discharge) also causes the expansion agent in the negative active material to lose its effect due to oxidation, and increases the crystallization of irreversible sulfates. Frequent overuse(excessive discharge) can cause the active substance to lose its activity prematurely, and the conversion ability of the active substance is weakened when charging, resulting in the decay of the lead-acid battery capacity to accelerate the waste lead-acid battery.

4, fall, fall, collision caused the battery plastic shell damage, in serious cases will cause the ear and the inner damage of the pole plate to completely invalidate the battery, prematurely scrapped.
