As the number of lithium-ion batteries in products increases, so has the number of counterfeit batteries on the market. These fake batteries tempt consumers with lower prices and claims of better performance, but they come up short in all the important areas: quality, durability, and especially safety.

Authentic original equipment manufacturer (OEM) batteries undergo safety testing and certification. Counterfeit batteries do not, and therefore may not have the proper protection inside the cells to prevent overcharging and overheating, which can lead to serious injuries and damage from thermal runaway.  

Counterfeit batteries made with inferior components are not only dangerous, but also unreliable, and can cause your device to fail or underperform — the more reason to know which battery is right for your device and buy the real thing.

It is difficult to tell a counterfeit battery from a real one, but there are a few ways to spot fakes. There are also best practices you can follow to help make sure you are buying certified OEM products.

Through this initiative, the Electrochemical Safety Research Institute (ESRI) shares its research findings on counterfeit batteries to encourage consumers to avoid safety risks by buying authentic products from trusted sources.
