KP4491-1 - Lincoln Electric Viking Replacement CR2450 Lithium Battery

Reliable Power for Precision Welding Protection

The Lincoln Electric KP4491-1 CR2450 Lithium Battery is a critical component for maintaining the safety and performance of your Viking auto-darkening welding helmet. In the demanding environment of industrial fabrication, the reliability of your personal protective equipment is paramount. This high-quality lithium coin battery is engineered specifically to meet the power requirements of Lincoln Electric's advanced Auto-Darkening Filters (ADF). With a substantial capacity of 620 mAh, it provides a robust energy reserve that ensures your lens switches from light to dark in a fraction of a millisecond, protecting your vision from harmful UV and IR radiation every time you strike an arc.

Unlike generic batteries that may suffer from inconsistent voltage output, this genuine Lincoln Electric replacement part is designed to work in harmony with the solar assist technology found in Viking helmets. The battery acts as a primary power source that is supplemented by the solar panel during welding, a synergy that significantly extends the operational life of the cell. This ensures that your helmet remains responsive even during low-amp TIG welding or in obstructed lighting conditions where the solar panel alone might not suffice.

Compatibility is key when selecting maintenance parts for your safety gear. The KP4491-1 is the designated replacement for a broad spectrum of the Viking lineup, including the premium 3350 Series, the 3250D FGS, the 2450 and 2450D Series, and the 1840 Series. Installing the correct battery is essential not just for power, but for maintaining the validity of your equipment's warranty and performance certifications. Whether you are performing heavy structural welding or intricate maintenance work, ensuring your helmet has a fresh, high-capacity power source is the first step in guaranteeing a safe and productive workday.
