SUIDIAN / BATTERY ASSEMBLY
The connection matters.
Share your device requirements. Define the cell, interface and package together before sample evaluation.
- Electrical profile
- Voltage, average current, pulse peak and cut-off voltage.
- Physical interface
- Dimensions, cell layout, lead length, connector and polarity.
- Sample evaluation
- Drawing approval, test conditions and acceptance criteria.
APPLICATION REQUIREMENTS
Start with the duty cycle.
Application examples guide selection. Compatibility and operating life require device-specific evaluation.
Water & gas metering
Transmission interval, pulse load, temperature and life target.
IoT & wireless sensors
Communication load, available space and environmental limits.
Industrial equipment backup
Equipment model, original battery, voltage, connector and polarity.
QUALITY / PRODUCT DOCUMENTATION
Evidence for the exact configuration.
Match the documents to your model, assembly and intended shipment.
Cell data
