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.
