Optrel CR2032 lithium battery (1 pc): genuine power supply for your welding helmet
Genuine Optrel CR2032 lithium batteries are a basic requirement for the correct operation of the advanced auto-darkening filters (ADF) in your helmet. In professional welding, where milliseconds decide whether your eyes stay safe, a reliable power source matters as much as the quality of the optics. This set is more than a spare energy supply: it gives you the certainty that Optrel protection technology will work with certified precision every time you strike an arc.

Technology details
Reliable power for key ADF technologies
Modern auto-darkening filters (ADF) in Optrel helmets use a hybrid power system that combines solar cells with lithium batteries. The battery is not just an emergency backup: it is the component that keeps the filter ready to work immediately, especially for the first weld of the day or in poor lighting. The stable voltage from a genuine CR2032 battery ensures a fast and precise response from advanced systems such as ShadeTronic® and Autopilot. Non-genuine replacements with non-standard characteristics can delay darkening or make the protection shade unstable, which is a direct risk to your eyesight. Genuine cells are the basis for keeping the certified safety level and full performance of your helmet.
