Intrinsically Safe Batteries

Certified Batteries for Any Hazardous Environment

Powering equipment in hazardous locations requires more than just a standard battery; it demands a certified power source engineered to prevent ignition in explosive atmospheres. Intrinsically safe and explosion-proof batteries are designed with specific safety circuits, construction, and energy-limiting characteristics to ensure they cannot produce a spark or heat capable of igniting flammable gases, vapors, or dust. Whether your operation falls under ATEX, IECEx, or North American Class/Division standards, using a certified battery is a non-negotiable aspect of workplace safety and regulatory compliance.

Our selection covers a comprehensive range of chemistries and form factors to meet the demands of various certified devices. From high-energy-density primary lithium batteries for long-deployment sensors to robust rechargeable NiMH battery packs for daily-use instruments like gas detectors and two-way radios, we provide reliable, certified power solutions that maintain the integrity of your equipment’s safety rating.

How to Choose the Right Intrinsically Safe Battery

Selecting the correct battery is critical for both safety and operational reliability. An incorrect choice can void your equipment’s certification and create a significant safety risk. To ensure you make a compliant choice, consider the following key factors:

• Certification and Area Classification: The battery’s certification must match the requirements of the hazardous area where it will be used. This includes the correct ATEX Zone, IECEx Group, or North American Class and Division rating. Always verify the markings on the battery against your site’s safety requirements.
• Equipment Compatibility: Intrinsically safe equipment is often certified as a complete system, including the specific battery model. Never substitute a battery with a non-approved model, even if the voltage and size are similar. Doing so invalidates the system’s certification. Always refer to the device’s user manual or control drawing for a list of approved batteries.
• Battery Chemistry and Performance: Different applications require different battery chemistries. Primary cells like Lithium-thionyl chloride (Li-SOCl2) offer long life and high energy density, ideal for low-power monitoring devices. Secondary (rechargeable) cells like NiMH are suited for frequently used handheld equipment.
• Voltage, Capacity, and Temperature: Ensure the battery’s electrical specifications (Voltage, mAh) match the device’s requirements. Additionally, check the battery’s certified operating temperature range (T-rating) to ensure it is safe for your ambient environmental conditions.

Common Applications for Explosion Proof Batteries

Certified batteries are the unseen power behind critical operations across numerous industries where safety is paramount. Their specialized design makes them essential for a wide array of portable and remote equipment, including:

• Oil & Gas: Powering portable gas detectors, pressure calibrators, remote terminal units (RTUs), and wellhead monitoring sensors.
• Mining: Essential for miners’ cap lamps, personal alert systems, two-way radios, and underground environmental sensors.
• Chemical and Pharmaceutical: Used in portable analyzers, data loggers, inspection cameras, and communication devices within classified processing areas.
• Emergency Services: Powering radios, intrinsically safe flashlights, and monitoring equipment used by first responders and hazmat teams.
• Aviation & Marine: For use in refueling zones, maintenance areas, and onboard vessels where flammable vapors may be present.

FAQs

What makes a battery intrinsically safe or explosion proof?

An intrinsically safe or explosion-proof battery is designed and constructed to prevent it from causing an explosion in a hazardous environment. This is achieved through energy-limiting circuits that prevent sparks, temperature control to avoid hot spots, and often robust, sealed enclosures. These batteries undergo rigorous testing and certification by third-party bodies to standards like ATEX, IECEx, and UL to verify their safety.

What is an ATEX certified battery?

An ATEX certified battery is a battery that has been approved for use in potentially explosive atmospheres within the European Union, according to the ATEX Directive. The certification includes specific markings that detail the level of protection and the zones (e.g., Zone 0, 1, or 2) in which it is safe to operate, ensuring it meets stringent EU safety requirements for hazardous locations.

Are lithium batteries safe to use in hazardous locations?

Yes, lithium batteries can be safe for hazardous locations, provided they are specifically designed, tested, and certified for that purpose. Certified intrinsically safe lithium batteries incorporate advanced safety features like protection circuits and thermal fuses to manage their high energy density safely. You must only use lithium batteries that carry the appropriate hazardous area certification (e.g., ATEX, IECEx) for your specific environment.

What is the difference between an intrinsically safe battery and a standard battery?

The primary difference lies in their design and certification. An intrinsically safe battery contains internal protective circuitry to limit the voltage and current to levels below what is needed to ignite a specific hazardous atmosphere. Standard batteries lack these safety circuits and can easily produce sparks or heat sufficient to cause an explosion, making them unsafe for use in classified hazardous areas.

How do I find the correct certified battery for my equipment?

The safest and most reliable method is to consult the equipment’s original user manual, certification documents, or the manufacturer’s control drawing. These documents will list the specific part numbers of all approved batteries. Using a non-approved battery will void the equipment’s intrinsic safety certification and compromise safety. If you are unsure, our expert team can help you identify the correct, compliant battery for your certified device.
