CR1220 vs CR1225 Evolution: The Ultra-Dense CR1225 3V 50mAh Lithium Coin Cell for Industrial Automation, Telecom, and Enterprise Security
In the architecture of modern enterprise hardware, spatial efficiency is everything. When a standard 12mm cell lacks the longevity your circuit demands, the CR1225 3V 50mAh Lithium Manganese Dioxide (LiMnO2) Battery steps in.
Measuring a precise Φ12.5 × 2.5mm, this form factor capitalizes on a slight 0.5mm height increase over the CR1220 to deliver an incredible 30% boost in energy density (50mAh). It is the ultimate micro-power reservoir engineered specifically for high-availability industrial, communication, and security systems that require absolute operational autonomy.

The CR1225 Advantage: Engineering Highlights
1. Enhanced 50mAh Payload for Extended Lifecycles
By expanding the internal vertical volume to 2.5mm, this cell holds a richer formulation of high-purity LiMnO2. For design engineers, this translates directly to fewer field maintenance cycles and a guaranteed 10+ year service life for passive backup applications.
2. High-Fidelity Voltage Stability under Pulse Loads
Equipped with low internal resistance, our CR1225 prevents "voltage dip" during sudden current spikes. When an enterprise printer or telecom hub runs a self-diagnostic or flashes wireless data packets, the voltage stays flat and reliable.
3. All-Weather Kinetic Engineering (-20°C to 70°C)
From unheated outdoor security arrays in sub-zero winters to hot, unventilated server racks and industrial printing floors, our proprietary organic electrolyte ensures chemical kinetics remain stable without cell swelling or capacity drop-offs.

Frequently Asked Questions
Are CR1220 and CR1225 batteries interchangeable?
They share the same diameter of 12.5mm and nominal voltage of 3V. However, the CR1225 is 2.5mm thick, whereas the CR1220 is 2.0mm thick. If your device's battery holder has the vertical clearance to accommodate the extra 0.5mm, the CR1225 is a superior upgrade because it provides 50mAh instead of 38mAh, extending your device's life by roughly 30%.
Why is the CR1225 preferred for industrial printer motherboards?
Industrial printers generate considerable heat and vibration during continuous operation. Our CR1225 features a rugged stainless-steel casing and an operating temperature ceiling of 70°C. This, paired with its 50mAh capacity, ensures the printer's internal memory and real-time clock remain intact for up to a decade without requiring maintenance.
What is the shelf life of your factory-direct CR1225 battery?
Thanks to our precision crimp-sealing tech and ultra-pure raw materials, the self-discharge rate is kept below 2% per year under standard storage conditions. This yields an optimal shelf life of 10 years from the date of manufacture.
