Battery Engineers

Quallion was founded in 1997 to design and manufacture “QUALity Lithium ION” rechargeable power sources for unique and challenging applications.  To this end, Quallion developed a power source that was reliable, delivered unrivaled performance, and could be safely packaged into a maintenance-free product for implant into the human body or launch into orbit.  Given the unique tolerances and operating conditions associated with medical devices and aerospace systems, this was no simple challenge. 

Quallion assembled a team of experienced battery engineers with expertise in battery mechanics, chemistry, and process design.  Quallion was ready to revolutionize the battery industry.

In 2013, Quallion was acquired by EnerSys, the global leader in stored energy solutions for industrial applications.  Quallion operates under EnerSys’ Advanced Systems Division (EAS). More information regarding EnerSys can be found at
