Which Devices Are Compatible with CR1616 Batteries?
CR1616 batteries power devices requiring compact, high-energy cells. Common applications include car key fobs, fitness trackers, LED lights, calculators, and medical tools like thermometers. Always check your device’s manual for voltage and size requirements. Tenergy’s CR1616 is interchangeable with equivalent cells like Panasonic CR1616 or Energizer 1616 but offers cost savings in bulk packs.
How Long Do Tenergy CR1616 Batteries Last?
Under typical use, Tenergy CR1616 batteries last 1–3 years, depending on device power demands. In low-drain gadgets like watches, they may exceed three years. The lithium chemistry ensures consistent voltage output until depletion, avoiding gradual declines seen in alkaline batteries. Storage in cool, dry conditions preserves shelf life.
Battery longevity also depends on usage frequency. Devices activated intermittently (e.g., key fobs) conserve power more effectively than constantly running gadgets. Temperature extremes can reduce performance – avoid exposing batteries to environments below -20°C or above 60°C. For optimal results, replace all batteries in multi-cell devices simultaneously to prevent uneven power distribution.
| Device Type | Average Lifespan |
|---|---|
| Car Key Fob | 2-3 years |
| Digital Thermometer | 18-24 months |
| Fitness Tracker | 12-18 months |
Are Tenergy CR1616 Batteries Rechargeable?
No. Tenergy CR1616s are single-use, non-rechargeable lithium batteries. Attempting to recharge them can cause leakage, overheating, or rupture. For reusable options, consider NiMH button cells, but ensure compatibility with your device’s voltage requirements (most 3V devices won’t support 1.2V NiMH).
How to Safely Store and Handle CR1616 Batteries?
Store batteries in their original blister cards until use. Avoid extreme temperatures and humidity. Keep away from metal objects to prevent short-circuiting. When installing, use clean gloves to avoid oil transfer. Dispose of depleted cells at recycling centers—lithium batteries shouldn’t be tossed in household trash due to environmental risks.
What Are the Alternatives to Tenergy CR1616 Batteries?
Alternatives include Panasonic CR1616, Energizer 1616, and Sony CR1616. While performance is similar, Tenergy’s 10-pack offers better value for frequent users. For devices requiring slightly different sizes, consider CR1620 (thicker) or CR1632 (higher capacity), but verify fitment first.
Why Choose a 10-Pack with Two Blister Cards?
The dual-blister packaging ensures freshness by sealing five batteries per card. This reduces oxidation risks and extends shelf life. It’s cost-effective for households with multiple devices or professionals needing backups. Separate cards also simplify organization—use one card now, store the other for future needs.
This packaging design minimizes exposure to air and moisture compared to loose battery storage. Each blister card acts as a protective barrier while maintaining easy access. The divided format also helps users track consumption – when the first card is empty, it serves as a visual reminder to reorder before fully depleting stock.
| Packaging Type | Advantage |
|---|---|
| Single Blister | Compact storage |
| Dual Blister | Extended freshness |
| Bulk Container | Lower per-unit cost |
Expert Views
“Tenergy’s CR1616 packs strike a balance between affordability and reliability,” says a battery industry consultant. “Lithium chemistry’s stable discharge curve makes them superior to alkalines in critical applications like medical devices. The two-card packaging is smart—it minimizes waste for users who don’t need all 10 cells immediately.”
FAQ
- Q: Can I use CR1616 instead of CR2032?
- A: No. CR2032 batteries are thicker (3.2mm vs. 1.6mm) and have higher capacity. Using mismatched sizes may damage devices.
- Q: Do Tenergy batteries come with a warranty?
- A: Yes. Tenergy offers a 1-year warranty against defects. Contact their support for replacements.
- Q: Are these batteries mercury-free?
- A: Yes. Tenergy CR1616s comply with RoHS standards, eliminating mercury, cadmium, and lead.
