Beware - The Lithium Batteries You're Using Could Be Defective!

When lithium-ion battery cells emerge from the factory, they receive one of three critical grades - A, B, or C - based on a rigorous assessment of their quality.


Grade-A cells, the elite selection, represent the pinnacle of performance. Each receives a unique QR code during production, immortalizing its exact manufacturing history and specifications. You can trust an A-grade cell to deliver unparalleled power output, cycle life, and longevity. Only the very best cells, free from any defects, achieve this coveted rating.


The majority receive a Grade-B designation. No industrial process is perfect, and small imperfections inevitably occur. Cells that fall just shy of the exacting standards for voltage, capacity, or cosmetic blemishes receive the Grade-B designation. To preserve quality control and product reputation, manufacturers wipe the unique tracking codes from these "factory seconds" before shipping. While still functional, Grade-B cells come with no guarantees about long-term reliability.


An even smaller number are consigned to Grade-C, the lowest tier, plagued by more substantial flaws. Where do these lower-graded cells end up? Major automakers demand the utmost in safety and dependability from electric vehicles, so they reject anything less than top-shelf Grade-A cells. However, less critical applications such as e-bikes, floor cleaners, forklifts, and golf carts have more lenient needs. Traders acquire and repackage Grade-B and C cells to sell into these emerging markets as an affordable upgrade over traditional lead-acid batteries.
