3M Speedglas G5 Battery and Filter Guide
The 3M Speedglas G5 series is the current generation flagship from Speedglas, built around a modular platform where the same ADF filter works across the G5-01, G5-02, and G5-03 helmet shells. If you are moving from the 9100 series to the G5, the first thing to know is that the battery is different - and there is only one of them, not two.
The G5 ADF Battery: One CR2450, New Part Number
The G5 series ADF uses a single CR2450 battery. The 3M part number for this battery is 44-0320-00 (also referenced as 602000 in some 3M catalogs).
This is a different part number from the 9100 series battery (04-0320-00), even though both are CR2450 chemistry. The G5 ADF requires only one battery, compared to the two required by the 9100 series ADF.
Key battery specs:
- Chemistry: CR2450 3V lithium
- Quantity required: 1 (one battery per ADF)
- Compatible with: G5-01 and G5-01VC welding filters
- Availability: 3M authorized distributors, specialized welding safety suppliers, Amazon
The G5 battery is located within or near the ADF filter cartridge. 3M has an official YouTube video titled “Speedglas G5-03E: How to install the battery & cover lenses” that demonstrates the replacement procedure for the G5-03 series. A similar process applies to G5-01.
G5 Filter Compatibility: Cross-Model
One of the G5 series’ most useful design decisions is filter cross-compatibility:
G5-01 filters fit the G5-03 helmet, and G5-03 filters fit the G5-01 helmet.
This simplifies parts stocking across mixed fleets. A shop running both G5-01 and G5-03 helmets can stock a single ADF filter part number. The G5-01/03TW welding filter (part number 610021) fits both G5-01, G5-03 Pro, G5-03 Pro Air, and G5-03 E helmets.
The G5 series includes:
- G5-01: Standard lightweight configuration
- G5-02: Different shell/form factor; uses G5-02 specific front cover (08-0700-63) but compatible ADF
- G5-03 Pro: Professional grade with enhanced features
- G5-03 Pro Air: Integrated air supply for clean-air applications
- G5-03 E: Slim lightweight version
Cover Lenses for the G5 Series
Outside Cover Lens - Shared with 9100 Series
The outside protection plate for the G5 series is the same 06-0200-51 used across the 9100 series. This cross-compatibility is a real practical benefit - users upgrading from a 9100 to a G5 can continue using the same outside cover lenses.
Variants available:
- 06-0200-51 - standard, 10/pack
- 06-0200-52 - scratch-resistant, 10/pack
- 06-0200-53 - high-temperature, 10/pack
Inside Cover Lenses: G5-Specific
The inside protection plates for the G5 series are different from the 9100 series inside plates. G5 inside plates are ADF-specific - verify the correct part number for your G5 ADF variant through 3M’s parts catalog at 3m.com/speedglas.
G5-02 Front Cover - 08-0700-63
The G5-02 uses a shell-front replacement part (08-0700-63) that is specific to its form factor and is not shared with G5-01 or G5-03.
G5 ADF Bluetooth Feature
The G5 welding filters include Bluetooth connectivity to the 3M Connected Equipment app. Through the app, users can:
- Access additional ADF settings and fine-tuning
- View welding statistics and arc time documentation
- Access help documentation and maintenance reminders
The Bluetooth is part of the ADF filter electronics, not a separate module. It functions on the same CR2450 battery that powers the ADF. Battery life with Bluetooth active is adequate for normal use, but if battery life seems shorter than expected, Bluetooth connectivity adds a marginal drain.
Adflo Battery: Separate System for G5 Pro Air
The G5-03 Pro Air variant integrates with the Adflo PAPR system. If you are running a G5-03 Pro Air, the Adflo has its own separate lithium-ion rechargeable battery (heavy-duty part 837631, approximately 10-13 hours runtime). This is entirely separate from the ADF CR2450 battery (44-0320-00). Both need to be maintained independently.
For standard G5-01 and G5-03 Pro/E (non-Air) configurations, there is no PAPR battery - only the single CR2450 ADF battery.
G5 Series vs 9100 Series: Key Differences
| Feature | G5 Series | 9100 Series |
|---|---|---|
| ADF battery | 1x CR2450 (44-0320-00) | 2x CR2450 (04-0320-00) |
| Outside cover lens | 06-0200-51 (shared) | 06-0200-51 (shared) |
| Inside cover lens | G5-specific | Variant-specific |
| Filter cross-compat | G5-01 ↔ G5-03 | Not cross-compat |
| Bluetooth | Yes | No |
| Natural Color Tech | Yes (G5 ADF) | 9100XXi only |
Where to Buy G5 Parts
G5 series parts are available from:
- 3m.com/speedglas - full parts catalog, Bluetooth app download
- Haus of Tools (hausoftools.com) - stocks 44-0320-00 battery
- Enviro Safety Products (envirosafetyproducts.com)
- JAM Industrial Supply (jamindustrialsupply.com)
- Amazon - search “Speedglas G5 battery 44-0320-00”
Because the G5 is a relatively new platform (introduced around 2020-2022), availability at some regional welding supply houses may be more limited than the 9100 series. Online ordering from 3M-authorized sources is reliable.
Maintenance Schedule
Before each shift: Verify the ADF low-battery indicator is not flashing (check per ADF user instructions). Inspect inside and outside cover lenses for damage.
Monthly: Clean sensor windows with a soft cloth and isopropyl alcohol. Check headband ratchet function.
As needed: Replace outside cover lens (06-0200-51) when spatter-pitted or scratched. Replace inside cover lens when fogged or scratched. Replace battery (44-0320-00) when the low-battery indicator flashes consistently.
Annually: Replace ADF battery proactively in heavy-use environments regardless of indicator status.
Frequently Asked Questions
What battery does the 3M Speedglas G5 use? A single CR2450 3V lithium battery, 3M part number 44-0320-00. Unlike the 9100 series which uses two batteries (04-0320-00), the G5 ADF uses only one.
Is the G5 battery (44-0320-00) the same as the 9100 battery (04-0320-00)? Both are CR2450 chemistry, but the part numbers are different and the G5 requires one while the 9100 requires two. Do not interchange part numbers when ordering.
Do G5-01 and G5-03 filters work in each other’s helmets? Yes. 3M confirms that G5-01 filters fit G5-03 helmets and vice versa. This cross-compatibility simplifies parts inventory.
Can I use the 9100 outside cover lens (06-0200-51) in my G5 helmet? Yes. The 06-0200-51 outside protection plate is shared across both the 9100 and G5 series.
Does the G5 have Bluetooth? Yes. The G5 ADF filters include Bluetooth connectivity to the 3M Connected Equipment app for extended settings, statistics logging, and documentation.
What is the G5-03 Pro Air? The G5-03 Pro Air is the version of the G5-03 helmet designed for use with the Adflo PAPR system, providing combined welding and respiratory protection. It includes a face seal for positive-pressure air supply and uses both the standard G5 ADF battery and a separate Adflo lithium-ion battery.
