Jackson NexGen Welding Helmet Battery and Parts Guide
The Jackson NexGen is a workhorse helmet that brought digital ADF controls to a broader price point. It shares its battery platform with the Insight, uses the same 370 Speed Dial headgear, and is maintained with a compact set of part numbers. This guide covers everything you need.
Battery: CR2450, Part 15984
The NexGen ADF runs on CR2450 3V lithium coin cells. The official Jackson replacement is part 15984 - a pair of CR2450 cells sold together.
Part 15984 covers both the NexGen and the Insight series. If your shop has both helmets, one battery part number covers both.
Jackson’s recommendation: Use only Duracell or Energizer CR2450 cells. When the NexGen was designed, the battery compartment dimensions were validated against those two brands. Generic CR2450 cells can be slightly thinner and make poor contact with the spring terminals, causing intermittent ADF behavior that is difficult to diagnose.
One pair provides approximately 800 hours of use.
Installation:
- Open the battery compartment inside the ADF unit
- Remove the old pair of cells
- Install fresh cells with correct polarity
- Close the compartment
- Test darkening with an arc or IR remote
Where to buy: Part 15984 is available at jacksonsafety.com, cyberweld.com (9.65 for a pair as of last check), and Amazon.
Cover Lens Kit: Part 22606 (NexGen Lens Kit)
The NexGen uses its own cover lens kit. The 22606 NexGen lens kit provides:
- 5 outer cover lenses (5 in x 2 in)
- Designed specifically for NexGen ADF dimensions
The inner safety plate is available separately. For exact inner plate part numbers, check jacksonsafety.com or contact a Jackson distributor.
Replace outer lenses whenever they show scratches, pitting, or discoloration that reduces visibility or sensor responsiveness.
Lens Retainer: Part 15977
The NexGen and Insight share a lens retainer, part 15977. This is the clip or retention piece that holds the outer safety plate in position. If it breaks or is lost, replacement retainers are available at cyberweld.com (7.75).
Headgear: Part 20696
The 370 Speed Dial headgear (part 20696) fits the NexGen along with the Insight, TrueSight II, BH3, and other Jackson Safety models.
Features:
- Fine-tooth ratchet adjuster operable with gloves
- Three-position slider for lens distance adjustment
- Engineered detents for up and down positions
- Easy grip and turn rotation
NexGen ADF Replacement
The replacement ADF for the NexGen is part 16622 (NexGen EQC Auto-Darkening Lens). This is the complete replacement cartridge if the electronics fail. Confirm model compatibility at jacksonsafety.com before ordering, as NexGen variants exist.
Quick Parts Reference

| Headgear | 20696 | 370 Speed Dial |
| ADF Cartridge | 16622 | NexGen EQC replacement |
What the NexGen Does Well
The NexGen’s digital controls were ahead of its price class when it launched. Variable shade 9-13, adjustable sensitivity and delay, and a digital display made it a step up from analog competitors at the same price. It is TIG-capable at maximum sensitivity and covers all standard welding processes.
The NexGen’s one practical limitation is the need to stick with name-brand CR2450 cells. This is a small constraint but one that catches welders off guard when they grab a generic two-pack from a hardware store.
FAQ
What battery does the Jackson NexGen use? CR2450 coin cells, part 15984 (pair). Use Duracell or Energizer only.
How many batteries does the NexGen take? Two CR2450 cells per ADF unit, sold as a pair in part 15984.
Can I use generic CR2450 in the NexGen? Jackson says no. Generic cells may be thinner than spec and make intermittent contact. Use Duracell or Energizer.
What is the lens kit part number for the NexGen? 22606 for the outer lens kit (5 in x 2 in format).
Is the NexGen ADF compatible with the Insight shell? The NexGen and Insight are related but use different ADF cartridges (16622 vs 46128). Do not substitute between them without confirming fitment.
Does the NexGen work for TIG welding? Yes. Set sensitivity to maximum for low-amperage TIG arc detection.
Where can I buy NexGen replacement batteries? Jacksonsafety.com, cyberweld.com, and Amazon.
How long do the batteries last in the NexGen? Approximately 800 hours per pair under normal use conditions.

Storing the NexGen Between Sessions
The NexGen, like the Insight, has electronics that draw a small background current from the CR2450 pair even during storage. For welders who put the NexGen away for weeks or months between projects, the 800-hour rated battery life is misleading - it counts arc hours, not calendar time.
Remove the battery pair before extended storage. Slot them into a small bag in the helmet case so they are ready when you need them. If the helmet has been stored for more than two months with cells installed, start your next session with a fresh pair from part 15984.
Why Jackson Recommends Only Duracell and Energizer
The NexGen was designed and dimensioned at a time when only Duracell and Energizer CR2450 cells were available for dimensional validation. Off-brand CR2450 cells manufactured today may be within spec or may be fractionally thinner. When a cell is too thin, the spring contact in the NexGen’s battery compartment does not make reliable contact across the full face of the cell.
The result is intermittent ADF behavior - the helmet darkens sometimes and not others, or shows a false low-battery reading with cells that measure 3.0 volts at rest. This is not a helmet defect. It is a battery fitment issue. The fix is switching to Duracell or Energizer CR2450 cells.
This recommendation applies equally to the Insight. Both helmets share the 15984 battery part number and the same fitment history.
