CP335849-V 3.0V 2300mAh Li-MnO2 Thin Cell Battery Technical Overview
The CP335849-V is a flat Li-MnO2 primary lithium battery designed for compact electronic products that require stable 3.0V power, long storage capability, and a thin mechanical profile.
Product Identity
According to the product specification PDF, the document applies to the Li-MnO2 Battery CP335849 supplied by VTC Power Co., Ltd. The model is listed as CP335849-V, and the assembled cell parameter table identifies the battery as CP335849-2300mAh. It is a single-cell assembly with stainless steel terminals and a nominal voltage of 3.0V.
Main Electrical Parameters
The nominal capacity is 2300mAh when discharged at a 1mA load to a 2V cut-off voltage at 23°C. The dispatch open-circuit voltage is specified between 3.10V and 3.3V. For current capability, the PDF lists a maximum continuous discharge current of 800mA and a maximum pulse discharge current of 1200mA under the stated test and pulse conditions.
| Parameter | PDF Value |
|---|---|
| Model | CP335849-V / CP335849-2300mAh |
| Chemistry | Li-MnO2 thin cell |
| Nominal Voltage | 3.0V |
| Nominal Capacity | 2300mAh |
| Discharge Cut-off Voltage | 2V |
Mechanical Design and Integration
The battery is specified with a maximum assembled size of 49mm(L) x 58mm(W) x 3.3mm(T) and an approximate weight of 22g. The drawing page shows tab geometry and confirms a slim flat-cell format. The handling section recommends ultrasonic welding or spot welding for tab connection with a PCM or other parts; manual soldering is restricted by temperature, time, and repeat limits to protect the cell body.
Temperature, Storage, and Self-Discharge
The operating temperature range is -40°C to +70°C. The recommended storage temperature is -5°C to +35°C with 45~75% relative humidity. The storage life is listed as 10 years under the recommended storage conditions, and the self-discharge rate is specified as ≤2% after one year of storage at 25°C.
Discharge Curve Summary
The PDF includes a typical discharge curve at 23°C±2°C with 5mA, 100mA, and 1000mA profiles. The chart indicates a flatter and longer discharge profile at lower current, while higher current discharge reaches the cut-off voltage earlier. The SVG below is a best-effort editable reconstruction from the PDF chart image, so numerical precision should be treated as approximate.
Application Fit
Based on the 3.0V primary lithium chemistry, 2300mAh capacity, thin profile, and current specifications, the CP335849-V is best positioned for compact electronics that need standby power, periodic sensing, or scheduled data transmission rather than continuous high-drain operation.
