The OiD124345-1900 is a premium-grade polymer lithium-ion battery cell engineered as a core power component for manufacturers developing equipment intended for use in hazardous or potentially explosive environments.
Produced by Shenzhen Jianheng Technology Co., Ltd, this cell is designed to deliver stable electrical performance, predictable energy behavior, and robust safety characteristics, supporting system-level explosion protection and intrinsically safe (IS) design concepts.
In hazardous area applications, explosion protection is achieved at the complete device level, not by individual components alone.
The role of the battery cell is to provide electrical stability, controlled energy release, and consistent behavior under stress, forming a reliable foundation for safety engineering.
The OiD124345-1900 supports this approach through:
Stable nominal voltage (3.7 V) with a flat discharge profile
Limited continuous charge and discharge capability (0.5C), facilitating current control
Low internal resistance to minimize heat generation
Strict factory voltage control to ensure predictable integration behavior
This lithium-ion cell is a component.
Final ATEX, IECEx, or other explosion protection certifications are obtained at the complete device level, through appropriate system design incorporating certified protective circuits, current limiting, thermal management, and safety barriers.
Shenzhen Jianheng Technology provides detailed technical data and test information to support customers’ safety engineering and certification processes.
| Parameter | Specification | Value for IS-Oriented Design |
|---|---|---|
| Nominal Voltage | 3.7 V | Stable voltage platform |
| Rated Capacity | Min. 1900 mAh | Predictable energy budgeting |
| Max Charge Voltage | 4.2 V | Standard Li-ion integration |
| End-of-Discharge Voltage | 3.0 V | Controlled depth of discharge |
| Max Continuous Charge Current | 0.5C (950 mA) | Easier current limiting |
| Max Continuous Discharge Current | 0.5C (950 mA) | Supports energy control |
| Internal Resistance | ≤ 80 mΩ | Reduced internal heating |
| Nominal Energy | 7.03 Wh | Suitable for low-power IS devices |
| Mode | Temperature Range | Condition |
|---|---|---|
| Charging | 15 ~ 45°C | 0.5C CCCV |
| Charging (Low Temp) | 5 ~ 15°C | 0.2C CCCV |
| Discharging | -10 ~ 45°C | 0.2C – 0.5C |
Charging below 0°C is not permitted due to lithium plating risk and reduced cycle life.
The following tests demonstrate the inherent robustness of the cell, providing a reliable basis for device-level explosion protection design:
Overcharge resistance (no fire, no explosion)
Over-discharge tolerance
Thermal cycling (-40°C to 75°C)
Mechanical shock and vibration
Drop test (1.0 m)
High temperature & high humidity exposure
Low pressure (aviation transport conditions)
These results confirm the cell’s suitability as a high-reliability power component in safety-critical designs.
(For Certified Equipment)
Portable gas detectors and air quality monitors
Intrinsically safe sensors and transmitters
Inspection and maintenance instruments for oil & gas facilities
Industrial IoT devices intended for hazardous locations
Emergency and safety equipment
All applications require appropriate certified protective circuitry and system-level approval.
