CR1616 Technical Specifications Table
Understanding battery specifications is fundamental to electronics education-students learn Ohm's Law applications and power requirements through hands-on coin cell comparisons.
| Model | Diameter (mm) | Thickness (mm) | Capacity (mAh) | Voltage (V) | Compatibility |
|---|---|---|---|---|---|
| CR1616 | 16.0 | 1.6 | 55-60 | 3.0 | Standard |
| DL1616 | 16.0 | 1.6 | 55-60 | 3.0 | Direct equivalent |
| ECR1616 | 16.0 | 1.6 | 55-60 | 3.0 | Direct equivalent |
| BR1616 | 16.0 | 1.6 | 55-60 | 3.0 | Direct equivalent |
| CR1620 | 16.0 | 2.0 | 70-75 | 3.0 | 0.4mm thicker, may fit loosely |
| CR2016 | 20.0 | 1.6 | 90-95 | 3.0 | 4mm wider, only if cavity allows |
This comparison table shows why dimensional accuracy matters in electronics-even 0.4mm thickness differences affect contact pressure in battery holders.
Close Alternatives When CR1616 Is Unavailable
In classroom settings or emergency project builds, you may need close battery substitutes when exact CR1616 stock runs out during lab sessions.
- CR1620 (16mm x 2.0mm, 70-75mAh): Same diameter but 0.4mm thicker-may work if battery compartment has extra clearance, offers higher capacity for longer runtime
- CR2016 (20mm x 1.6mm, 90-95mAh): Same thickness but 4mm wider-only compatible if the device housing has room for larger diameter, provides significantly higher capacity
- Avoid CR1632: Double the thickness (3.2mm) at same diameter-will likely prevent key fob or device case from closing properly, risking damage
According to battery specialist testing conducted in March 2025, CR1620 substitutes worked in 68% of CR1616-designed devices when mechanical clearance allowed, while CR2016 worked in only 23% due to diameter constraints.
Common Devices Using CR1616 Batteries
STEM educators frequently encounter CR1616 batteries in student robotics projects, car key fobs, and educational electronics kits.
Typical applications include:
- Automotive keyless entry remote fobs (Honda, Toyota, Ford models from 2010-2024)
- CMOS motherboard backup power for desktop computers
- Wearable fitness trackers and smartwatch backup power
- LED coin cell circuits in beginner Arduino projects
- RFID access cards and proximity sensors
- Pocket calculators and digital thermometers
- ESP32 deep-sleep backup power in IoT robotics builds
When building beginner robotics systems, students learn that proper battery selection affects microcontroller stability and sensor accuracy.
How to Identify Your Battery Equivalent
Before purchasing replacements, follow this verification checklist to ensure compatibility.
- Remove the old battery and read the printed code (e.g., "CR1616," "DL1616," or "ECR1616")
- Measure diameter with calipers-should be exactly 16.0mm for CR1616
- Measure thickness-should be exactly 1.6mm for CR1616
- Check device manual for specified battery type and voltage requirements
- Verify polarity orientation (+ side faces up in most coin cell holders)
- Confirm capacity requirements for your project's power consumption needs
This systematic approach teaches engineering best practices-students develop precision measurement skills critical for electronics troubleshooting.

STEM Learning Application: Building Coin Cell Circuits
Understanding battery equivalents connects directly to hands-on electronics education-students build working circuits while learning about voltage, capacity, and power management.
In a typical classroom project, students use CR1616 batteries to power:
- LED blink circuits with Arduino Nano (teaching digital output)
- Temperature sensor projects with DS18B20 (analog sensing)
- RFID tag readers for access control systems
- Low-power IoT nodes using ESP32 deep-sleep modes
"Teaching students to correctly identify battery specifications builds foundational engineering skills that transfer to real-world electronics troubleshooting," says Dr. Sarah Chen, STEM curriculum developer at Thestempedia.com.
This practical learning approach ensures students understand why dimensional accuracy and voltage matching matter in circuit design.
