Engineering Breakthroughs: Why Design with Our CR1220?
1. High-Density 38mAh Capacity in a Compact Frame
By optimizing the internal cathode-anode ratio and utilizing ultra-pure manganese dioxide, our CR1220 achieves a true 38mAh capacity. This provides up to 15-20% longer operational life than standard commercial coin cells under equivalent low-current pulses.
2. -20°C to 70°C Weather-Proof Operation
From unheated outdoor commercial security gates in winter to blistering hot telecom enclosures in mid-summer, this battery maintains a flat, dependable 3V discharge profile. Its optimized electrolyte prevents thermal contraction and volatile expansion.
3. Anti-Corrosion & Anti-Leakage Shielding
Designed for enterprise hardware, our CR1220 features a heavy-duty casing and a proprietary heat-resistant leakage-proof seal. It guarantees that valuable circuitry is safe from corrosive acid leaks over its entire 10-year shelf life.
