Is Battery Depletion Covered Under Warranty?

Battery depletion is covered under warranty. Battery Introduction: A battery is a type of cell, also known as a storage battery, which works by converting chemical energy into electrical energy. The common battery refers to a lead-acid battery, mainly composed of lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. Battery Working Principle: It uses a lead plate filled with sponge-like lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and a 22-28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When the battery discharges, metallic lead acts as the negative electrode, undergoing oxidation to form lead sulfate; lead dioxide acts as the positive electrode, undergoing reduction to also form lead sulfate.
