Technical Specifications Analysis
Both CR2016 and CR2032 have a diameter of 20mm, but their thickness differs significantly (1.6mm vs. 3.2mm). This is similar to comparing a coin and a button. CR2032 weighs 40% more than CR2016 (approx. 3g vs. 2.1g). This size difference directly affects device compatibility. Ultra-thin smart cards may deform if forced to use CR2032 (Figure 1 shows a 50% thickness difference in side view comparison).
| Model | Capacity | Typical Usage Scenario |
| CR2016 | 90mAh | Car key remote (10 uses/day) lasts 8 months |
| CR2032 | 240mAh | Smartwatch (daily data sync) lasts 12 months |
A capacity bar chart shows that CR2032 holds 2.6 times more energy than CR2016. However, in ultra-low power devices such as mini electronic scales, CR2016 is preferable due to its smaller size.
Both batteries have a nominal voltage of 3V, but their discharge curves reveal key differences. CR2032 maintains a stable output of 3.0-2.8V across 80% of its battery life (blue curve in Figure 2), whereas CR2016 starts to drop noticeably below 50% capacity (red curve). This makes CR2032 more suitable for medical devices requiring stable voltage.
Product Advantage Comparison 1: Panasonic CR2032 uses laminated technology, maintaining 90% capacity even at -30°C, far exceeding the industry average.
In emergency replacements, using CR2016 instead of CR2032 will cause:
Product Advantage Comparison 2: Energizer CR2032 features exclusive Power Seal technology, reducing self-discharge to 3% per year, retaining 75% capacity even after 10 years in storage.
Used batteries should be disposed of through:
Product Advantage Comparison 3: GP batteries use an eco-friendly formula, with heavy metal content 42% lower than EU standards, certified by EPBA Green Label.
| Brand | Extreme Temperature Performance | Annual Self-Discharge Rate |
| Panasonic | 90% efficiency at -30°C | ≤5% |
| Energizer | Stable operation at -20°C | 3% |
| Tianqiu | Best performance at 25°C | 8% |
Three steps to identify genuine products:
A four-dimensional comparison shows that CR2032 is the preferred power source for smart devices due to its high capacity and stability. However, CR2016 remains irreplaceable in ultra-thin applications. Consumers should choose IEC60086-certified leading brand products for both performance and safety.

In most devices requiring a single CR2016 battery, the CR2032's greater thickness prevents proper insertion into the original battery housing/slot intended for CR2016 cells.
CR2016 and CR2032 batteries, despite having identical diameters and voltage capacities, cannot be interchanged due to variations in their thickness.
In most cases, replacing a CR2016 with a CR2025 is possible provided the device's battery compartment has sufficient space for the increased thickness of the CR2025. Nevertheless, following the manufacturer's specified battery type remains the optimal practice for device compatibility and safety.
