Choosing the Right Model
Choose CR2016 if you need:
- Thinnest profile (1.6mm) for ultra-compact designs
- Low-power backup applications
- Space-constrained PCB layouts
- 90mAh capacity sufficient for your application
- Available in both vertical and horizontal tab configurations
Choose CR2025 if you need:
- Medium capacity (165mAh) for extended backup time
- Balance between size and capacity
- Standard 20mm diameter, 2.5mm height
- Horizontal tab configuration for easy PCB mounting
- Most common size for timer and PLC applications
Choose CR2032 if you need:
- Maximum capacity (220mAh) for longest backup time
- Most popular button battery size
- Higher current capability for demanding applications
- Horizontal tab configuration for standard PCB layouts
- Best choice for critical backup power needs
Installation Guidelines
Soldering Tips:
- Use low-temperature soldering (max 260°C)
- Solder quickly (less than 3 seconds per joint)
- Avoid overheating the battery
- Ensure proper polarity: positive (+) side is larger, flat surface
- Negative (-) side has the rim/edge
PCB Mounting:
- Verify tab orientation matches your PCB design
- Clean PCB pads before soldering
- Use flux for better solder joints
- Inspect solder joints for quality
- Test voltage after installation
