ABOUT THE IEC 60086 battery standard
IEC 60086 is an international standard that encourages battery manufacturers to ensure that their batteries are interchangeable according to standard form, fit and function. Interchangeability means the battery can be used in a much wider range of products, meaning you can boost adoption – and revenue, as a result. This fact helps end users, as well as manufacturers of devices that use your batteries. Certification to the IEC battery standard shows that a battery complies with the standard.
TÜV SÜD is an accredited IEC BATTERY testing partner

There are many benefits to demonstrating that a battery complies with the IEC battery standard:
- Enhance consumer trust in your brand
- Increase the likelihood that device manufacturers will include or recommend your batteries in their products
- Demonstrate safety
- Gain access to global markets
Our technical experts are involved with international advisory boards and in developing standards and are up to date with all the latest changes with regards to battery technology and testing.
We have a highly efficient testing and certification process for a wide range of battery types:
- Primary Battery – standards IEC/EN 60086-1, IEC/EN 60086-2 are intended to standardize primary batteries with respect to dimensions, nomenclature, terminal configurations, markings, test methods, performance, safety and environmental aspects.
- Primary Lithium Battery – standards IEC/EN 60086-1, IEC/EN 60086-2, IEC/EN 60086-4 are intended to standardize primary lithium batteries with respect to dimensions, nomenclature, terminal configurations, markings, test methods, performance, safety under intended use and reasonably foreseeable misuse and environmental aspects.
- Primary Battery with Aqueous Electrolyte – standards IEC/EN 60086-1,IEC/EN 60086-2, IEC/EN 60086-5 are intended to standardize primary batteries with aqueous electrolyte with respect to dimensions, nomenclature, terminal configurations, markings, test methods, performance, safety under intended use and reasonably foreseeable misuse and environmental aspects.
- Primary Lithium Battery for Watches – standards IEC/EN 60086-1, IEC/EN 60086-3, IEC/EN 60086-4 are intended to standardize primary lithium watch batteries with respect to dimensions, nomenclature, terminal configurations, markings, test methods, performance, safety under intended use and reasonably foreseeable misuse and environmental aspects.
- Primary Battery with Aqueous Electrolyte for Watches – Standards IEC/EN 60086-1, IEC/EN 60086-3, IEC/EN 60086-5 are intended to standardize primary watch batteries with aqueous electrolyte with respect to dimensions, nomenclature, terminal configurations, markings, test methods, performance, safety under intended use and reasonably foreseeable misuse and environmental aspects.
