Miller CR2450 Lithium Replacement Battery for Auto-Darkening Helmets

Don't Get Caught in the Dark: Genuine Miller Replacement Batteries

There is nothing more frustrating for a welder than striking an arc only to find that their auto-darkening helmet isn't switching. A dead battery can stop production in its tracks and, more importantly, pose a safety risk. The Miller 217043 CR2450 Lithium Battery is the essential consumable every welder should have in their kit. Designed to deliver reliable 3-volt power, this battery ensures your helmet's sensors react immediately to the welding arc, every single time.

This isn't just any watch battery; it is a high-performance lithium cell selected by Miller Electric to power their top-tier welding hoods. Whether you are running a Miller Digital Infinity with its massive viewing area or the industry-standard Digital Elite, this battery provides the juice needed for clear optics and responsive controls. It features a robust 600 mA capacity, meaning fewer battery changes and more arc time. The battery is also built to withstand the rigors of the job site, functioning perfectly in extreme temperatures ranging from freezing cold to blistering heat (-22°F to 140°F).

Compatibility and Usage

Before purchasing, it is important to verify your helmet's requirements. This CR2450 battery fits a vast array of Miller and Hobart helmets. It is the correct part for:

• Miller T94 and T94i Series
• Miller Digital Infinity Series
• Miller Digital Elite and Elite Series
• Miller Performance Series
• Miller Weld-Mask 2
• Hobart Impact, Pro, Endeavor, and XVX Series

Important Note: Most of the high-end digital lenses require two (2) batteries to operate. This product is sold as a single unit, so we highly recommend purchasing a pair to ensure a complete replacement. Keeping a spare set in your tool bag is a smart move to avoid downtime. This battery does not fit the Miller Classic series or the older analog Pro-Hobby helmets.

Maintain the performance of your welding helmet with genuine Miller consumables. Using the correct battery prevents potential damage to the lens electronics and ensures the warranty on your expensive equipment remains valid. Shop with confidence and keep your vision protected with the Miller 217043.
