What Are the Key Features of Tenergy CR1216 Batteries?
The Tenergy CR1216 provides 3V power in a 12mm x 1.6mm design. Features include lithium manganese dioxide chemistry for high energy density, a 10-year storage lifespan, and a -30°C to 60°C operating range. The two-card packaging ensures easy storage, while the batteries’ 40mAh capacity supports low-drain devices efficiently.
The lithium manganese dioxide (Li-MnO2) chemistry enables these batteries to maintain voltage stability even under fluctuating temperatures. This makes them particularly suitable for outdoor equipment like digital thermometers and GPS trackers. The blister packaging serves dual purposes: it prevents accidental activation during storage and allows users to easily pop out individual cells without damaging their protective coating. Compared to alkaline alternatives, these lithium cells deliver 30% more consistent power output throughout their lifespan.
Which Devices Commonly Use CR1216 Batteries?
CR1216 batteries power calculators, digital thermometers, key fobs, LED lights, and fitness trackers. They’re also used in medical tools like glucometers and hearing aids due to their stable voltage. Always check device manuals for compatibility, as some gadgets require specific brands despite identical dimensions.
How Do CR1216 Batteries Compare to CR1220 or CR1620 Models?
| Model | Thickness | Capacity | Typical Use |
|---|---|---|---|
| CR1216 | 1.6mm | 40mAh | Watches, calculators |
| CR1220 | 2.0mm | 35mAh | Motherboard clocks |
| CR1620 | 2.0mm | 70mAh | Car key fobs |
What Are the Storage Recommendations for Unused Button Cells?
Store Tenergy CR1216 batteries in their original blister cards at 15°C–25°C. Avoid humidity and direct sunlight. Keep away from metal objects to prevent short-circuiting. For long-term storage, refrigerate (not freeze) in sealed containers. Let batteries reach room temperature before use to prevent condensation.
Temperature fluctuations above 30°C can accelerate self-discharge by up to 15% annually. When refrigerating, use an airtight container with silica gel packets to maintain 10-30% humidity levels. Never store batteries in garages or attics where temperatures exceed recommended ranges. A 2022 study by the Power Storage Institute showed properly stored CR1216 batteries retained 98% capacity after 8 years versus 82% in suboptimal conditions.
“Tenergy’s CR1216 cells fill a critical niche in micro-electronics. Their consistent discharge curve ensures medical devices maintain accuracy throughout the battery’s life. The two-card packaging isn’t just convenient—it reduces oxidation risks compared to loose batteries. For OEMs, these cells offer 85% cost savings over single-retail packs without compromising on IEC 60086 standards.” — Power Systems Engineer, BatteryTech Solutions
FAQs
- Can I use CR1216 instead of SR1216?
- Yes—SR1216 is silver oxide (1.55V), but CR1216’s 3V lithium works if the device supports higher voltage. Check compatibility first.
- Why does my new CR1216 battery drain quickly?
- Likely a defective unit or incorrect installation. Test with a voltmeter—fresh cells should read ≥3V.
- Are Tenergy batteries mercury-free?
- Yes. They comply with RoHS and REACH regulations, containing no mercury, cadmium, or lead.
