Jackson TrueSight II Battery and Lens Guide
Here is the most important fact about the Jackson TrueSight II before you read anything else: it does not use CR2450 coin cells. It uses two AAA batteries. If you walked into a welding supply house asking for a CR2450 for your TrueSight II, you walked out with the wrong thing. This guide covers the correct battery and every other replacement part for the TrueSight II.
Battery: Two AAA Batteries
The Jackson TrueSight II ADF runs on two standard AAA lithium batteries. They are included with the helmet. When they run out, replace them with AAA lithium cells from any hardware or welding supply store.
The TrueSight II’s battery compartment is located inside the ADF unit. The design accommodates AAA cells because the TrueSight II’s larger ADF body has room for the slightly larger cell format, and AAA lithium cells deliver more total capacity per cell than the CR2450 coin format.
Battery life rated at 3,000 hours - significantly longer per set than the typical 600-800 hours from a pair of CR2450 coin cells in comparable helmets.
This makes the TrueSight II particularly well-suited for production environments where battery maintenance overhead is a real consideration.
Why the TrueSight II Uses AAA Batteries
The TrueSight II’s large ADF - 3.25 in x 4.00 in, giving 13 square inches of viewing area - is one of the biggest in the industry. That ADF body physically accommodates the AAA format. The payoff is longer battery life and wider availability of replacement batteries.
AAA lithium cells can be bought at any grocery store, hardware store, or gas station. You will never be stuck searching for a specific coin cell part number at 7 PM when a welding job runs long.
Cover Lenses: External Safety Plate 30320
The outer safety plate for the TrueSight II is part 30320 - the TrueSight II External Safety Lens in clear polycarbonate. It measures approximately 2 in x 4.25 in.
This clear plate protects the ADF face from direct spatter. Replace it when scratched or pitted. Grainger stocks the 30320 (Grainger item 892UN4). The outer plate is also available at jacksonsafety.com and welding distributors.
ADF Cartridge: Part 46158
If the TrueSight II ADF fails, the replacement cartridge is part 46158 - the TrueSight II Series ADF Cartridge (4.00 in x 3.25 in).
46158 specs:
- Viewing area: 3.25 in x 4.00 in (13 sq in)
- Modes: Weld, Torch, Grind
- Shade range: 5-8 (cut/torch mode), 9-13 (weld mode), shade 3 (grind)
- 4 arc sensors
- TIG rated down to 3 amps
- Optical clarity: 1/1/1/1
- Auto-on ADF
- 5-year warranty on lens
- Built-in magnification lens holder
The 46158 replaces the entire ADF assembly, dropping into the existing TrueSight II shell.
Headgear: Part 20696
The 370 Speed Dial replacement headgear, part 20696, is compatible with the TrueSight II along with the Insight, BH3, NexGen, and other Jackson Safety models. It features a fine-tooth ratchet and three-position slider for precise fit adjustment.

The Verdict on the TrueSight II
The TrueSight II delivers the largest viewing area in the Jackson lineup, a 5-year ADF warranty, three operational modes (weld, torch, grind), and 3,000-hour battery life from two AAA cells. For welders who do mixed-process work or who spend long days at the machine, it is one of the most complete helmets in the mid-to-premium tier.
The one thing to know going in: the AAA battery format, while convenient, means the helmet body is slightly bulkier than coin-cell equivalents. For tight confined-space welding, this may matter.
