Panasonic CR1225-VBY2 3V Lithium Coin Cell Battery with Vertical PCB Solder Pins (50mAh, LiMnO2)

Ensure long-term backup power for your Real-Time Clocks (RTC) and non-volatile memory chips with the genuine CR1225-VBY2 lithium manganese dioxide ($\text{LiMnO}_2$) coin cell battery. Featuring factory-welded vertical 2-pin solder legs, this 3V primary battery ($50\text{ mAh}$ capacity) is engineered for direct wave soldering onto printed circuit boards without requiring a separate battery holder.

Manufactured with high-purity lithium chemistry, the CR1225-VBY2 provides an extremely low self-discharge rate ($<1\%$ per year at room temperature), allowing reliable operation over extended service lives up to 10 years. Its vertical pin orientation optimizes PCB surface footprint in space-critical applications such as smart gas/water meters, automotive control modules, industrial PLCs, medical monitoring devices, and security hardware.

Key Features:

• Pre-Welded Vertical Solder Pins: Directly solders onto circuit boards (THT) for maximum mechanical vibration resistance.
