EP35AQ 7.2V 3100mAh Intrinsically Safe ATEX Battery with IP68-Rated Enclosure for Hazardous Areas

EP35AQ 7.2V Intrinsically Safe ATEX Battery Explosion Proof Power for Hazardous Areas
7.2V 3100mAh Intrinsically Safe ATEX Battery Explosion Proof Power for Hazardous Areas
Explosion Proof Battery for Hazardous Area Handheld Equipment
The EP35AQ is a 7.2V 3100mAh lithium polymer battery pack engineered for intrinsically safe and ATEX-oriented systems used in explosive and hazardous areas such as oil & gas facilities, mining, petrochemical plants, and gas station handheld equipment.
Using premium lithium polymer cells and a precision 2S1P pack architecture, EP35AQ is designed to support hazardous area power solutions requiring controlled energy release, predictable behavior, and compliance-aligned integration with ATEX battery systems.

Core Advantages
Engineered for Intrinsic Safety and ATEX-Compatible Power
Intrinsic Safety & ATEX Design Principles
The EP35AQ pack is engineered in accordance with intrinsic safety and ATEX design principles, referencing GB3836 / Ex ib IIB T4 energy limitation standards and ATEX system integration requirements.
Rather than relying solely on external mechanical barriers, our safety approach focuses on limiting electrical energy, current, and thermal output at the cell, circuitry, and pack architecture levels, minimizing ignition risk even under fault conditions.
This makes EP35AQ suitable as an ATEX battery component within certified handheld devices and hazardous area battery systems.

Branded Lithium Polymer Cells with Low Self-Discharge
  • Uses 3.6V 3100mAh lithium polymer cells
  • Polymer chemistry offers enhanced mechanical stability and reduced leakage risk compared with cylindrical chemistries
  • Low self-discharge ensures predictable stand-by performance
These qualities make the EP35AQ ideal as a reliable explosion proof battery pack for mission-critical handheld equipment.

Multi-Level Protection Circuitry
Integrated battery protection provides:
  • Overcharge protection (OVP)
  • Over-discharge protection (UVP)
  • Over-current protection (OCP)
  • Short-circuit protection (SCP)
All protection thresholds are precisely configured for intrinsically safe and ATEX system requirements, ensuring multilayer safety from cell level to pack architecture.

Rugged Packaging for Harsh Environments
  • IP68-rated enclosure for dust and water resistance
  • Wide operating temperature range: -10 °C to +55°C (discharge)
  • Stable performance under humid and vibration-prone industrial conditions

Long Life and Low TCO
  • Low self-discharge for long standby storage
  • Optimized cycle profile for extended service life
  • Lower total cost of ownership (TCO) supports sustainability

Frequently Asked Questions (FAQ)
Q1: What does "ATEX battery" mean?
An ATEX battery refers to a battery component designed to support the requirements of ATEX-compliant systems used in explosive atmospheres. EP35AQ is engineered to support ATEX system integration when paired with certified intrinsically safe equipment.
Q2: Is this battery "ATEX certified"?
EP35AQ is designed following intrinsically safe and ATEX-oriented design principles. Certification status depends on system-level testing of the complete device or solution in which the battery is integrated.
Q3: Can EP35AQ replace a standard 7.2V battery in my device?
Not without proper evaluation. In hazardous areas, the entire device must meet intrinsic safety or ATEX certification. EP35AQ is intended as a power component within such systems.
Q4: How many charging cycles can EP35AQ sustain?
Under standard test conditions (0.2C charge / 0.5C discharge), EP35AQ typically provides 500+ cycles with >80% capacity retention, depending on usage conditions.
Q5: Where is this ATEX-compatible battery most commonly used?
Common applications include oil & gas inspections, mining safety equipment, hazardous site analysis tools, portable communications in Zone-classified areas, and other handheld devices requiring controlled energy power solutions.
