Why the life of lead-acid batteries is not long

1. Move the charger casually, the charger circuit is relatively small, the welding port is easy to be disconnected during the vibration process, or the internal parts are easy to drift, which makes the entire parameter change and cannot be charged normally; 2. When the lead-acid battery is charged, sulfuric acid Lead forms lead oxide, and lead oxide is reduced to lead sulfate during discharge. When the concentration of lead sulfate in the electrolytic solution of the battery is too high or the static idle time is too long, it will form small crystals. These small crystals attract surrounding Lead sulfate, this phenomenon is called sulfide. The key mechanism leading to the failure and damage of lead-acid batteries is that the battery itself cannot be guarded against vulcanization; 3. Most car controllers have a speed limit plug, and some manufacturers or dealers simply remove the speed limiter, which can attract people who value car speed. Customers can also reduce costs. Such a car has a very large current when driving at high speeds, which will seriously shorten the battery life; 4. The influence of sulfuric acid concentration: the increase in acid density is beneficial to the capacity of the positive plate, but the self-discharge of the battery increases, The corrosion of the grid is also accelerated, which also promotes the loosening and shedding of lead dioxide. With the increase of the acid density used in the battery, the cycle life decreases; 5. The influence of the discharge current density: As the discharge current density increases, the battery life Decrease, because under the conditions of high current density and high acid concentration, the positive lead dioxide is promoted to loosen and fall off.
