15984 - Jackson Safety CR2450 Lithium Replacement Batteries (2-Pack)

Technical Overview of Jackson Safety 15984 Batteries

The Jackson Safety 15984 represents a specific configuration of the CR2450 lithium manganese dioxide coin cell, optimized for use in high-performance auto-darkening welding filters (ADF). These batteries are the designated OEM power source for Jackson's advanced digital lens systems, specifically the NexGen and Insight series. The CR2450 form factor offers a significant capacity advantage over smaller coin cells (such as the CR2032), providing a nominal voltage of 3.0V and a high capacity that supports the sophisticated electronics found in modern variable-shade lenses.

Reliable power delivery is critical for the safety and functionality of an ADF. The Jackson 15984 batteries are engineered to maintain a stable voltage curve even under the intermittent high-drain conditions triggered when the welding arc is struck and the sensors activate the liquid crystal display shutter. A stable power supply ensures that the switching speed—the time it takes for the lens to darken—remains within the millisecond specifications required to protect the user's eyes from flash burn. These batteries are rated to provide up to 800 hours of active use, depending on the specific settings and frequency of arc starts utilized by the operator.

This product is supplied as a package of two batteries. Since many professional-grade ADFs, including the NexGen, may require two batteries to operate (or the user may wish to carry a spare), this packaging configuration ensures that the technician has the necessary components to restore full functionality to their PPE immediately. The lithium chemistry provides excellent shelf-life characteristics, allowing these batteries to be stored in a tool crib or maintenance locker for extended periods without significant degradation of charge. It is important to note that due to lithium battery transport regulations, these items generally have restrictions regarding air shipment.

Installation of the 15984 batteries into compatible Jackson Safety helmets is straightforward, typically involving a slide-out tray or a coin-slot battery cover located on the interior of the ADF cartridge. Proper polarity must be observed during installation to prevent damage to the lens electronics. These cells are non-rechargeable primary batteries and should be disposed of according to local environmental regulations regarding lithium batteries.
