Is the BYD Song Battery Covered by a Lifetime Replacement Policy?

[AngeloLee]

BYD Song's battery does not come with a lifetime replacement policy. Regarding the warranty for BYD Song's battery, BYD offers a six-year or 150,000-kilometer warranty for the entire vehicle. For the fuel power system in pure fuel vehicles, the warranty is four years or 100,000 kilometers, while plug-in hybrid vehicles enjoy a six-year or 150,000-kilometer warranty. However, the battery cells are covered by a lifetime replacement service. Below is an extended introduction: 1. Introduction to Battery Cells: The so-called battery cells refer to the individual cells within the entire battery pack. However, these cells are highly integrated into the battery pack, and 4S shops do not have the technical capability to replace individual cells. Therefore, what appears to be a cell replacement is actually a battery pack replacement. 2. Conditions for Battery Replacement: According to BYD's battery replacement standards, when the battery degrades to a certain percentage, approximately around 66%, it may be considered for replacement. The vehicle needs to be taken to a 4S shop for inspection. If it meets the replacement criteria, the manufacturer will send a new battery for replacement.
