Industrial-grade, safety-focused rechargeable 18650 cylindrical lithium cell built on IMR chemistry for low-drain professional devices that demand reliability, thermal stability, and predictable performance in challenging environments.
The Uniross IMR18650-1200 is built on Lithium Manganese Oxide (IMR) chemistry, offering a safer alternative to cobalt-based ICR cells — delivering stable operation, reduced thermal risk, and consistent output across a wide temperature range. With a 1200 mAh capacity, ≤60 mΩ impedance, and a 600 mA maximum continuous discharge rating, this cell is ideal for instrumentation, sensing equipment, portable meters, emergency lighting, and low-power medical monitoring devices where safety and longevity matter more than high-current delivery.
Key Advantages
Enhanced Thermal Safety — IMR chemistry provides superior structural stability under stress, reducing the risk of thermal runaway and ensuring dependable performance in mission-critical environments. (“IMR – Lithium Manganese”)
Consistent Low-Drain Output — Optimised for continuous discharge up to 600 mA, making it well-suited for professional devices with steady, moderate power requirements. (“Max. Continuous discharge current: 600 mA”)
Low Internal Impedance — With ≤60 mΩ, the cell maintains stable voltage delivery for sensors, monitoring devices, and precision electronics. (“Impedance: ≤60 mΩ”)
Standardised Charging Compatibility — Fully compatible with standard 4.2V CC/CV charging systems, simplifying integration into existing battery architectures. (“Charge cut-off voltage: 4.2V”)
Wide Operating Temperature Range — Reliable performance from –20°C to 60°C discharge, suitable for field equipment and industrial environments. (“Discharge: –20°C ~ 60°C”)
Ideal Applications
Industrial sensors & measurement instruments
Portable diagnostic and monitoring devices
IoT gateways (low-power)
