A lead acid accumulator battery is a rechargeable storage battery. It is commonly used to store electrical energy. However, if the battery is fully discharged and not promptly recharged, several negative effects can occur.
When a lead acid accumulator battery is fully discharged, the chemical reactions inside the battery stop. This means that the sulfuric acid electrolyte, which is necessary for the battery to function, becomes too weak to generate electrical energy. As a result, the battery loses its ability to hold a charge and cannot deliver the necessary power to run electrical devices.
Furthermore, the lead plates inside the battery can become sulfated when the battery is fully discharged. Sulfation occurs when lead sulfate crystals form on the surface of the plates, reducing the plate’s ability to react with the electrolyte and produce electrical energy. This can permanently damage the battery and reduce its overall lifespan.
In addition to sulfation, a fully discharged lead acid accumulator battery can also experience self-discharge. This means that the battery will continue to lose its charge over time, even when not in use. Self-discharge can occur due to internal chemical reactions and the natural leakage of electrical charge. As a result, the battery’s capacity and performance will be significantly reduced.
In conclusion, when a lead acid accumulator battery is fully discharged, it can suffer from weakened electrolyte, sulfation of the lead plates, and self-discharge. To prevent these negative effects and ensure the longevity of the battery, it is crucial to promptly recharge the battery when it is fully discharged.
