Product Description
OID503860 1250mAh 3.7V Intrinsically Safe Li-Ion Battery

The OID503860 is a high-performance rechargeable lithium-ion battery specifically engineered for hazardous environments where safety and reliability are non-negotiable. With intrinsic safety (IS) certification and proven operation at extreme low temperatures down to -40°C, this battery delivers consistent power in the world's most demanding industrial settings.

Key Features
  • Intrinsic Safety Certified: Designed to prevent ignition in flammable atmospheres, meeting stringent IS standards for hazardous area operation.
  • Extreme Low Temperature Performance: Reliable discharge and charge capability at -40°C, ensuring uninterrupted operation in Arctic, high-altitude, and cold storage environments.
  • High Energy Density: 1250mAh capacity in a compact form factor, delivering 4.625Wh of usable energy for portable and space-constrained devices.
  • Long Cycle Life: Engineered for 500+ charge-discharge cycles with minimal capacity degradation, reducing total cost of ownership.
  • Stable Discharge Platform: Maintains 3.7V nominal voltage with flat discharge curve, ensuring consistent device performance throughout the discharge cycle.
  • Leak-Proof Construction: Robust sealed design with advanced electrolyte formulation prevents leakage even under thermal stress and mechanical vibration.
