Can the BMW 523 battery be replaced by directly disconnecting the power?
1 Answers
BMW 523 battery cannot be replaced by directly disconnecting the power, as it may cause programming issues. It is recommended to replace the battery at a 4S shop. Definition of battery: A battery, also known as an accumulator, is a type of cell that converts chemical energy into electrical energy. The commonly referred-to battery is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. Working principle of the battery: The negative electrode is made of a lead plate filled with sponge-like lead, and the positive electrode is made of a lead plate filled with lead dioxide, using 22-28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When discharging, metallic lead acts as the negative electrode, undergoing oxidation to form lead sulfate, while lead dioxide acts as the positive electrode, undergoing reduction to form lead sulfate. When charging with direct current, lead and lead dioxide are generated at the two electrodes respectively. After removing the power source, it returns to its pre-discharge state, forming a chemical cell. A lead-acid battery is a rechargeable battery, known as a secondary cell, with a voltage of 2V. Typically, three lead-acid batteries are connected in series to achieve 6V. Automobiles use six lead-acid batteries connected in series to form a 12V battery pack. Regular lead-acid batteries require the addition of distilled water after some time to maintain the electrolyte at 22-28% dilute sulfuric acid.
