How often should the battery of a Magotan be replaced?

[DelPatrick]

The battery of a Magotan generally needs to be replaced every 3 to 4 years. Introduction to the battery: The battery, also known as a storage battery, is a type of cell that works by converting chemical energy into electrical energy. Typically, the battery referred to by people is a lead-acid battery. It is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. Working principle: It uses lead plates filled with sponge-like lead as the negative electrode, lead plates 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 and being converted into lead sulfate; lead dioxide acts as the positive electrode, undergoing reduction and being converted into lead sulfate. When the battery is charged with direct current, lead and lead dioxide are generated at the two electrodes respectively. After the power source is removed, it returns to its pre-discharge state, forming a chemical cell.
