The Tenergy CR2032 Lithium Battery Cells 100pcs (20 Cards) offers a cost-effective, reliable power solution for high-demand users. These 3V lithium batteries provide stable voltage, long shelf life (10+ years), and compatibility with devices like key fobs, medical tools, and IoT sensors. Bulk packaging reduces per-unit costs by 40-60% compared to single packs.

How Does Bulk Packaging Preserve Battery Performance?
Vacuum-sealed blister cards (5 batteries/card) maintain 0% humidity exposure. Each card has oxidation-resistant nickel plating contacts and ESD-safe polymer layers. Accelerated aging tests show only 2% capacity loss after 5 years in original packaging vs. 8% in opened packs.
Advanced moisture barriers in the card packaging utilize 7-layer laminated foil construction, preventing electrolyte evaporation even in tropical climates. The individual battery compartments feature laser-perforated tear lines that maintain seal integrity until use. For industrial users, each card’s sequential numbering enables precise inventory rotation through FIFO (First In, First Out) systems.
| Packaging Feature | Performance Benefit |
|---|---|
| Vacuum sealing | Prevents oxidation |
| Nickel-plated contacts | Reduces insertion resistance |
| ESD-safe polymer | Protects against static discharge |
Where Are Tenergy CR2032 Batteries Manufactured?
Produced in ISO 9001-certified facilities using Japanese lithium manganese dioxide (Li-MnO2) chemistry. Raw materials sourced from Tier 1 suppliers: Umicore (cathodes), Sumitomo (electrolyte). Each batch undergoes 23 quality checks including discharge curve analysis and 5G vibration resistance testing.
The manufacturing process employs automated optical inspection (AOI) systems that perform 12-point dimensional checks on each cell casing. All production lines maintain Class 8 cleanroom standards, with particulate counts below 100,000 particles per cubic meter. Final assemblies undergo thermal cycling tests from -40°C to +85°C to simulate decade-long environmental stress in accelerated timeframes.
“Tenergy’s bulk CR2032 solution revolutionizes inventory management. Their card-based packaging allows precise expiration tracking – hospitals we work with reduced battery waste by 68% through lot-number rotation systems.”

FAQs
- Can I mix old/new Tenergy CR2032 batteries?
- No – mixing reduces overall performance by 15-30%. Always replace all batteries in a device group simultaneously.
- How to store unused CR2032 cards?
- Keep sealed cards at 10-25°C in low-humidity environments. Avoid temperature fluctuations exceeding ±5°C/day to prevent electrolyte degradation.
- Are these compatible with Panasonic devices?
- Yes – Tenergy CR2032 meets all IEC 60086-3 standards required by Panasonic, Sony, and Toshiba OEM specifications.
