3.6V 2000mAh ATEX and Intrinsically Safe Battery for Hazardous Areas
The IST4-103443 is a 3.6V 2000mAh intrinsically safe lithium battery, engineered specifically for hazardous area applications where ignition risk must be strictly controlled.
Designed for ATEX-compliant handheld POS terminals and financial payment devices, this battery provides stable power while meeting the stringent safety expectations of oil & gas, chemical, and other explosive environments.
Intrinsic Safety Engineering - How This Battery Prevents Ignition
Intrinsic safety works by limiting electrical and thermal energy to levels that are incapable of igniting a defined hazardous gas mixture, even under fault conditions.
Unlike standard lithium batteries, the IST4-103443 is engineered with:
Controlled energy output
Restricted surface temperature
Multi-layer electronic protection
This design philosophy ensures safe operation in hazardous areas where flammable gases or vapors may be present.
Hazardous Area Power Solution: Key Features & Certifications
Ex ib IIB T4 - Explained for Engineering & Compliance Teams
Ex ib Suitable for Zone 1 hazardous areas, where explosive atmospheres are likely to occur occasionally during normal operation.
Gas Group IIB Covers common industrial gases such as ethylene, widely encountered in petroleum, chemical, and industrial facilities.
Temperature Class T4 Ensures the maximum surface temperature remains below 135 °C, reducing ignition risk for temperature-sensitive gases.
This classification makes the battery a reliable intrinsically safe power solution for hazardous areas, particularly in regulated industrial and financial environments.

Frequently Asked Questions (FAQ)
What is the difference between an intrinsically safe battery and a standard lithium battery?
An intrinsically safe battery is designed to limit electrical and thermal energy to non-ignitable levels, even under fault conditions. Standard lithium batteries may pose ignition risks in hazardous areas.
Can this battery be used in Zone 0 hazardous areas?
No. The Ex ib protection level is suitable for Zone 1. For Zone 0 environments, an Ex ia certified battery is required.
Is this battery suitable for continuous industrial operation?
Yes. The low internal resistance and stable discharge profile support long-term, reliable operation in regulated environments.
A Reliable Intrinsically Safe Battery for Hazardous Area Projects
Selecting the correct power source is critical for compliance-driven projects. The IST4-103443 is not a general-purpose battery with added protection—it is a purpose-built intrinsically safe battery, engineered to support safe operation in hazardous areas.
