[McLeila]

BYD's lifetime battery replacement policies are as follows: The warranty period for core components of BYD's new energy vehicles is 8 years or 150,000 kilometers, while the power battery cells come with a lifetime warranty. When the battery's power degrades by 20%, you can apply for a free replacement. Relevant information about automotive batteries is as follows: 1. Introduction: An automotive battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, the term "battery" refers to a lead-acid battery, which is mainly composed of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. 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.
