What Are the Key Features of Tenergy CR2025 Batteries?
Tenergy CR2025 batteries offer a 3V voltage output, 170mAh capacity, and a 10-year shelf life. The two-card packaging (5 batteries per card) includes tamper-proof seals for freshness. Constructed with lithium manganese dioxide chemistry, they operate in temperatures from -30°C to 60°C and meet IEC 60086-4 safety standards for steady performance in low-drain devices.
The advanced lithium manganese dioxide chemistry ensures minimal voltage drop during discharge cycles, making these batteries particularly effective for medical devices requiring stable power output. Each battery undergoes rigorous quality testing, including load simulation and temperature stress tests, to verify performance consistency. The stainless steel casing provides enhanced corrosion resistance compared to standard nickel alloys used in budget batteries, ensuring reliable contact points even after years of storage.

How Does Tenergy CR2025 Compare to Other Lithium Coin Cells?
Unlike alkaline alternatives, Tenergy CR2025 batteries maintain voltage stability under load, with 30% higher energy density. Compared to CR2032 cells, the CR2025 has a slimmer profile (2.5mm vs 3.2mm thickness) but lower capacity (170mAh vs 225mAh). Both share similar applications, though CR2025 fits devices requiring thinner power sources like hearing aids or compact sensors.
| Feature | CR2025 | CR2032 |
|---|---|---|
| Thickness | 2.5mm | 3.2mm |
| Capacity | 170mAh | 225mAh |
| Ideal Use | Wearables | Motherboards |
Why Choose Bulk Packaging for Coin Batteries?
The 10-pack dual-card system reduces per-unit cost by 40% versus single purchases. Separate cards minimize oxidation risks from repeated opening, preserving unused batteries. This packaging meets commercial users’ needs for inventory management while providing consumers with backup cells for multiple devices like car remotes and digital thermometers.
Businesses managing multiple devices benefit from batch coding on each card, enabling precise expiration date tracking across installations. The card design also reduces workplace accidents – technicians can safely carry individual cards instead of loose batteries. For consumers, the divided packaging serves as a built-in storage system: keep one card in a kitchen drawer for household gadgets and another in a toolbox for outdoor equipment. This separation prevents accidental mixing of new and used cells, a common issue with traditional multi-packs.
“Tenergy’s dual-card CR2025 packaging addresses a critical need in the battery market—balancing accessibility with preservation. The separation of cells into two groups significantly reduces oxidation compared to traditional 10-packs. For healthcare devices requiring fresh batteries, this design ensures at least one card remains factory-sealed until needed.”

FAQs
- Q: Can CR2025 batteries be used interchangeably with CR2032?
- A: No—CR2025 is 0.7mm thinner. Only use if device specifications allow vertical space adjustment.
- Q: How long do Tenergy CR2025 batteries last in continuous use?
- A: In a typical car key fob (3mA load), expect 6-12 months depending on usage frequency.
- Q: Are these batteries airport-safe?
- A: Yes—lithium content per cell (≤1g) meets FAA carry-on limits. Keep in original packaging for security checks.
