A new study highlights a potential flaw in the secondhand electric vehicle battery market, revealing that used batteries may suffer from an uneven distribution of cells, which could compromise performance and safety. Researchers warn that this imbalance—often undetected in standard testing—may reduce efficiency and shorten the lifespan of repurposed batteries. The findings suggest that current recycling and resale practices may need closer scrutiny to ensure reliability in the growing EV market. Experts emphasize the need for improved diagnostics to address this emerging issue before it affects widespread adoption.
