ATEX Intrinsically Safe Battery 3.6V 6700mAh
A Power System Component for Sensors in Hazardous (Classified) Areas

Product Overview
The IST4-213868SY is a 3.6V 6.7Ah intrinsically safe lithium battery pack engineered as a power system component for sensors and instrumentation operating in hazardous (classified) areas. Rather than a repurposed consumer battery, this solution is purpose-designed for applications where energy limitation, fault tolerance, and long-term stability are critical to explosion risk control. It is widely suitable for industrial environments requiring intrinsically safe power solutions, such as oil & gas, chemical processing, and process automation.

Key Advantages for Hazardous Area Applications
Engineered for Intrinsically Safe Systems
  • Designed around intrinsic safety (IS) energy-limiting principles
  • Supports T4 temperature class design targets
  • Controlled voltage, current, and thermal behavior to minimize ignition risk
Reliable Power for Sensors & Instrumentation
  • Stable 3.6V output optimized for low-power industrial sensors
  • Ideal for long-term operation of transmitters, detectors, and monitoring devices
  • Consistent performance in continuous duty cycles
Low Self-Discharge & Extended Service Life
  • Reduced standby energy loss
  • Longer maintenance intervals in hard-to-access installations
  • Supports energy-efficient and low-carbon operational strategies
Multi-Layer Safety Protection
  • Short-circuit protection
  • Over-charge protection
  • Over-discharge protection
  • Over-current protection
  • Over-temperature protection
These safeguards are essential for battery operation in hazardous areas, where fault energy must remain strictly controlled.

Safety Design & Compliance Framework
This battery is engineered in accordance with international intrinsically safe design concepts used in ATEX and IECEx systems.
Energy Limitation by Design
Key electrical parameters are intentionally constrained to support intrinsic safety objectives:
  • Nominal voltage (3.6V) selected to limit available electrical energy
  • Continuous discharge current ≤ 1.6A to restrict fault energy
  • Peak discharge current < 3A to prevent transient ignition scenarios
Thermal Risk Management
  • Controlled current paths and internal resistance
  • T4-aligned temperature behavior under normal and abnormal conditions
  • Protection circuitry designed to prevent thermal runaway escalation
Component Role in Certified Equipment
This battery is designed and tested as a component for incorporation into end equipment seeking ATEX / IECEx certification for use in:
  • Gas atmospheres (Zone 0 / 1 / 2)
  • Dust atmospheres (Zone 21 / 22)
Final certification and zone approval reside with the complete apparatus, as defined by applicable standards.

Why Choose an Engineered Intrinsically Safe Battery Pack?
Aspect Standard Lithium Battery Engineered IS Battery Pack
Energy Control Unrestricted Intentionally limited
Fault Behavior Unpredictable Defined & managed
Certification Support None Designed for certified systems
Thermal Risk Higher Controlled
Long-Term Reliability Variable Application-specific
In hazardous areas, how energy behaves during faults matters more than nominal capacity. This product is designed accordingly.

  • Gas Detection Systems
    Reliable power for fixed gas detectors monitoring explosive atmospheres, supporting continuous safety instrumented system (SIS) operation.
  • Process Instrumentation
    Backup or primary power for field instruments deployed in classified zones.
  • Monitoring & Control Devices
    Long-life power source for distributed sensing nodes in hazardous locations.

Customization & Integration Support
Our engineering team provides application-specific support, including:
  • Capacity and form-factor customization
  • Connector and harness options
  • Discharge profile optimization for sensor loads
  • Pre-certification technical review of power system design to support end-equipment approval processes

Frequently Asked Questions
Is this battery ATEX certified?
This battery is designed as a component for ATEX/IECEx certified equipment. Final certification applies to the complete device.
Can it be used in Zone 0 or Zone 1 areas?
It is designed for integration into equipment targeting these zones. Approval depends on the final system design.
What is the difference between explosion-proof and intrinsically safe batteries?
Explosion-proof relies on containment; intrinsically safe limits energy to prevent ignition. This product follows the intrinsically safe design philosophy.
Can you support integration into our sensor housing?
Yes. We provide technical support during the design and pre-certification phase.
