E-cigarette use is on the rise. The global e-cigarette market is expected to grow to $61.4 billion by 2025, according to a report from Research and Markets.1 Since the introduction of e-cigarettes in 2004, there has been an increase in e-cigarette fires and explosions resulting in personal injury and/or property damage.2
E-cigarettes and vaping devices feature a battery-powered heating element that heats up a solution (e-liquid) to produce a vapor. Poor quality or misused lithium batteries are known to cause e-cigarette related fires and explosions.
UL developed a voluntary industry standard UL 8139 to help manufacturers address lithium battery hazards for electronic cigarettes and vaping devices, also known as ENDS (electronic nicotine delivery systems). UL 8139 evaluates the safety of the electrical, heating, battery and charging systems of these products.

Please Note: E-cigarette consumables, including e-liquids, vapor substances, wicks and other particulate matter, and their long-term or physiological effects are outside the scope of UL’s evaluation.
Improve E-cigarette Battery Safety Now
Why is UL 8139 Testing Important?
- Enhances consumer safety
- Minimizes battery-related injuries
- Protects brand reputation
- Mitigates potential risks
- Boosts consumer confidence
With certification, UL identifies known lithium battery failures and design flaws. Manufacturers can rectify design flaws to prevent serious injury from lithium battery explosion and fires.
Consumers in any market can look for the recognizable UL mark to verify that the e-cigarette complies with UL’s stringent safety standards requirements.
UL 8139 testing procedures include:
- Battery management system evaluation for normal use and foreseeable misuse
- Mechanical stress testing
- Accidental activation
- Compatibility with interconnected systems
- Environmental resilience
UL is recognized as a global leader in battery safety testing. Our engineers are experienced in battery technology and test batteries to UL Standards as well as international, national, and regional regulations.
UL worked with the Consumer Protection Safety Commission (CPSC), the U.S. Food and Drug Administration (FDA), Health Canada and the American National Standards Institute (ANSI), as well as other industry stakeholders to develop UL 8139.
Testing and certification can be conducted at the following UL laboratories – Guangzhou, China, Ise, Japan, Northbrook, Ill. and Research Triangle Park, NC, USA.
