Where would we be without them?
A report by Freedonia Group, a US industry research firm, forecasts the global battery demand to rise 7,7% per year to USD 120 billion in 2019. The report says that secondary or rechargeable batteries will outpace throw-away types, and the fastest growing products will be rechargeable lithium-ion batteries.
These figures have been greatly impacted by the increased demand for portable devices, such as smartphones and wearable products including smart watches, fitness trackers, smart eyewear, smart clothing, medical devices, headphones, hearing aids and electronic watches to name a few.

Charging up safely
IECEE, the IEC System of Conformity Assessment Schemes for Electrotechnical Equipment and Components, plays an important role when it comes to certifying batteries. The IECEE CB Scheme, through its registered Certification Body Testing Laboratories (CBTLs) and National Certification Bodies (NCBs), tests and certifies batteries against IEC International Standards developed by IEC Technical Committee (TC) 21: Secondary cells and batteries.
These International Standards cover all secondary cells and batteries, irrespective of type and chemistries (i.e. lithium-ion, lead-acid, nickel-based) or application (i.e. portable, stationary, traction, electric vehicles or aircraft). They comprise all aspects such as safety, performance and dimensions, and labelling.
Some examples of IEC International Standards for batteries:
- IEC 60086 series for primary batteries covers dimensions, nomenclature, terminal configurations, markings, test methods, typical performance, safety and environmental aspects, for batteries used in many portable devices
- IEC 60952 series for testing performance and other aspects of aircraft batteries
- IEC 61982 series for testing performance and endurance of batteries for electric road vehicles
