Lincoln Electric Viking Replacement CR2450 Lithium Battery

Keep Your Viking Helmet Ready to Arc

Don't let a dead battery interrupt your workflow or compromise your safety. The Lincoln Electric KP4491-1 VIKING™ CR2450 Lithium Battery is the factory-specified replacement power source for your trusted Viking welding helmet. Designed for professional welders who demand consistency, this battery delivers the energy needed to drive the high-speed electronics within your auto-darkening lens. With a 620 mAh capacity, this lithium coin cell offers extended service life, reducing the frequency of replacements and ensuring your helmet is ready to go whenever you are.

This battery is more than just a generic coin cell; it is selected by Lincoln Electric to support the specific power management systems of the Viking series. It works alongside the helmet's integrated solar panel, which helps to recharge and extend the life of the battery during use. This dual-power system is a hallmark of the Viking line, providing the reliability needed for long shifts and complex fabrication tasks. When the battery eventually depletes, the replacement process is quick and tool-free on most models, allowing you to get back under the hood with minimal downtime.

The KP4491-1 is compatible with the most popular models in the Lincoln Electric range, including the industry-leading Viking 3350, the versatile 2450, and the compact 1840 series. Please note that certain advanced models, such as the Viking 3250D FGS and specific generations of the 2450 and 1840 series, may require two batteries for operation. We recommend keeping a spare set in your gear bag or shop locker. By using genuine Lincoln Electric consumables, you ensure that your ADF maintains its rated optical clarity and switching speeds, providing you with the best possible view of the puddle and the highest level of protection.
