The CP302752 Li-MnO₂ Pouch Cell is designed for electronic products that need more energy than an ultra-thin card-style cell can provide while still maintaining a low-profile mechanical design.
With a maximum thickness of 3.0 mm, a narrow 27 mm width, and a 52 mm length, CP302752 distributes its 1030 mAh nominal capacity across an elongated footprint. This geometry is particularly useful for wearable, adhesive, strip-shaped, or concealed electronic devices where battery thickness and width are tightly controlled.
A Slim Battery for Narrow Product Designs
Many compact products are not limited by total internal area, but by the thickness and width available for the battery.
CP302752 addresses this constraint with a narrow pouch construction that can be positioned along the length of a sensor, wearable patch, label, or compact electronic module.
This makes it especially attractive for products that need to remain:
- thin against the body or surface
- narrow enough for concealed installation
- lightweight
- free from the cylindrical bulge created by conventional cells
The result is greater freedom when designing electronics around an elongated or low-profile enclosure.
Balanced Energy and Discharge Performance
CP302752 provides 1030 mAh nominal capacity, a maximum continuous current of 300 mA, and a maximum pulse discharge current of 500 mA.
This electrical profile makes it suitable for products that operate at relatively low average power but periodically activate functions such as:
- sensor measurement
- wireless communication
- display updates
- data processing
- status indication
- alarm transmission
Compared with ultra-thin pouch cells optimized primarily around minimum thickness, CP302752 provides additional energy and current capability while remaining only 3.0 mm thick.
Wearable & Medical Electronics
The narrow, flat form factor is particularly relevant to body-worn electronics where device thickness directly affects comfort and usability.
Potential applications include:
Wearable Monitoring Patches
Suitable for selected ECG, temperature, biosensor, and other monitoring patches that require a flat primary battery integrated close to the body.
Compact Diagnostic Devices
Can be considered for disposable or portable diagnostic electronics where a conventional cylindrical battery would increase product thickness.
Medical Sensor Modules
Useful in selected low-profile sensing devices that combine continuous monitoring with intermittent processing or wireless communication.
Battery suitability for medical applications must be verified as part of the finished device’s electrical, safety, mechanical, and regulatory qualification process.
Slim IoT & Security Sensors
CP302752 can also be integrated into compact sensors designed to disappear into the surrounding environment.
Examples include:
Door & Window Sensors
The narrow cell profile is suitable for security sensors installed along frames, edges, or other restricted spaces.
Environmental Sensors
Applicable to thin temperature, humidity, light, or occupancy sensors mounted on walls, equipment, packaging, or furniture.
Wireless Status Sensors
Can support compact IoT nodes that remain in standby for extended periods and periodically wake to measure or transmit data.
Electronic Labels & Smart Packaging
The combination of a flat profile and moderate pulse capability also makes CP302752 relevant to selected electronic labels and intelligent packaging applications.
Possible uses include:
- electronic shelf labels
- smart logistics labels
- anti-tamper packaging
- shipment condition indicators
- compact wireless identification devices
Its elongated shape can be easier to integrate along the edge or rear surface of a label than wider pouch-cell formats.
Where CP302752 Fits in the Pouch Cell Range
CP302752 occupies a useful position between extremely thin cells and thicker high-current pouch batteries.
It is a strong candidate when a project requires:
- approximately 3 mm maximum battery thickness
- a narrow battery footprint
- more than 1 Ah nominal capacity
- moderate continuous current capability
- intermittent wireless or sensing loads
For applications where absolute minimum thickness is the priority, a thinner pouch cell may be preferable. Where substantially higher continuous or pulse current is required, a larger high-power format may provide greater electrical margin.
