We are proud to announce the official launch of the OID503860, a high-performance 1250mAh 3.7V lithium-ion battery that has successfully achieved intrinsic safety (IS) certification at an extreme operating temperature of -40°C. This milestone product is engineered to deliver reliable, safe power for portable electronic devices operating in the world's most challenging hazardous environments.
In hazardous area applications, power sources are often the limiting factor in device design. Batteries must not only provide sufficient runtime but also meet stringent safety requirements to prevent ignition in potentially explosive atmospheres. The OID503860 achieves both — combining a practical 1250mAh capacity with full intrinsic safety compliance down to -40°C, a temperature at which most lithium-based batteries experience severe performance degradation or fail safety testing altogether.
This dual achievement — high energy density plus extreme low-temperature safety certification — positions the OID503860 as a best-in-class power solution for hazardous area equipment manufacturers and system integrators worldwide.
The OID503860 has undergone rigorous evaluation by accredited testing laboratories and has passed all required intrinsic safety assessments at -40°C ambient temperature. Energy levels in both normal operation and simulated fault conditions remain safely below ignition thresholds for target gas groups, ensuring reliable protection in Zone 0, Zone 1, and Zone 2 hazardous areas.
With a nominal voltage of 3.7V and a rated capacity of 1250mAh, the OID503860 delivers 4.625 watt-hours of usable energy — an ideal balance between compact form factor and operational runtime. This makes it perfectly suited for portable gas detectors, communication handsets, headlamps, and other essential safety equipment.
The cell chemistry has been specially formulated to maintain discharge performance at sub-zero temperatures. Unlike standard Li-Ion cells that experience significant voltage sag and capacity loss in cold conditions, the OID503860 maintains stable output characteristics across its entire certified operating range.
While the -40°C certification is the headline feature, the OID503860 is also rated for continuous operation up to +60°C, providing reliable performance across an exceptionally broad temperature window suitable for arctic, desert, and everything in between.
The battery incorporates a multi-layer protection circuit module (PCM) that guards against overcharge, over-discharge, short circuit, and over-current conditions. This PCM is integral to the intrinsic safety design and has been validated as part of the full certification process.
The OID503860 is designed to power a wide range of portable and handheld equipment used in hazardous locations:
The OID503860 has been designed and tested in accordance with the IEC 60079 series of standards for explosive atmospheres. Third-party certification confirms compliance with intrinsic safety requirements applicable to portable battery-powered equipment.
