GNB Absolyte batteries are now manufactured under the Stryten Energy brand. While the name has changed, the proven AGM technology and performance remain the same. CPBS supplies and services both legacy GNB Absolyte and current Stryten Absolyte battery systems.
🎯 Quick Answer. Yes, GNB Absolyte batteries are still made and still available. They are simply sold under a new name. Stryten Energy (formerly GNB Industrial Power, a division of Exide Technologies) manufactures the identical battery on the identical line. GNB Absolyte GP is now Stryten Absolyte AGP.
Key facts:
- Same battery, new name: GNB Absolyte GP is now Stryten Absolyte AGP, confirmed by the August 2023 Berger Manufacturer’s Declaration.
- Still in production: made in the USA under ISO 9001:2015, with the same plates, Lead-Calcium-Tin alloy, containers, factory, and engineers.
- Who makes it now: Stryten Energy, the renamed former GNB Industrial Power industrial portfolio.
- Where to buy it: through an authorized Stryten distributor. CPBS is an authorized Stryten Energy reseller with a signed authorization letter on file.
- Lead time: 8 to 10 weeks domestic, longer internationally with 50% down at order.
- Legacy warranty: factory terms transferred with the rebrand; CPBS routes warranty questions through the Stryten warranty desk.

If you manage a facility running a legacy GNB Absolyte battery string, you have probably searched for a replacement and found that GNB appears to have vanished. The reassuring reality is simpler than it looks: the line was never discontinued. The brand was renamed. This guide explains what happened, proves the battery is unchanged, and gives you a verified path to buy and service both legacy GNB Absolyte and current Stryten Absolyte systems.
The guidance here draws on Tom Kierna, Battery Systems Specialist at CPBS, who spent 15 of his 40-plus years in industrial batteries on the GNB and Stryten side of the desk through this exact transition. CPBS is the battery division of Advanced Technical Services Inc. (ATS), founded 1981, ISO 9001 certified, headquartered in Chicago, and an authorized Stryten Energy reseller.
The Short Answer: GNB Is Now Stryten, and the Battery Is Unchanged
GNB Absolyte was not discontinued. Stryten Energy (formerly GNB Industrial Power, a division of Exide Technologies) makes the same battery under the Stryten name. The product you knew as GNB Absolyte GP is sold today as Stryten Absolyte AGP. Same plates, same Lead-Calcium-Tin alloy, same flame-retardant polypropylene containers, same manufacturing line, same factory, same engineers.
The single most important proof point is the Manufacturer’s Declaration of Design Continuity, signed August 17, 2023 by Stryten Director of Engineering Michael Berger. Berger states it plainly: “the design, engineering, and product manufacturing remains unchanged from the GNB product to the Stryten Energy product. The only change is the name.” That single sentence is the substitution authority procurement teams, warranty desks, and authorities having jurisdiction cite when a legacy GNB part number appears on a drawing and a current Stryten part number arrives on the truck.

The GNB to Stryten Brand Transition Timeline
Four dates explain how GNB Absolyte became Stryten Absolyte. The ownership changed hands twice and the brand was retired, but the product never left the line.
- 2000: Exide Technologies acquires GNB Technologies, folding the GNB industrial battery portfolio into Exide Industrial.
- August 2020: Atlas Holdings acquires Exide Industrial Americas and renames the business Stryten Manufacturing.
- 2022 to 2023: the GNB brand is officially retired as the portfolio transitions to Stryten Energy branding.
- March 6, 2023: Stryten issues the formal rebrand announcement renaming the GNB-branded industrial portfolio. GNB Absolyte GP becomes Stryten Absolyte AGP.
Five months later, on August 17, 2023, the Berger Declaration formalized that the rename carried zero design change. For the documentation trail in depth, see the CPBS GNB to Stryten compliance documentation guide.
What Stayed the Same, and What Changed
Every aspect of the physical product stayed the same. Only the paperwork changed. This is the distinction that matters when you are deciding whether a current Stryten Absolyte AGP cell will drop into a rack built for GNB Absolyte.
What stayed the same:
- AGM separator technology (absorbed glass mat under compression)
- Plate design and Lead-Calcium-Tin alloy
- 20-year design life at 25 degrees C float
- Capacity ratings (104 to 4,800 Ah at the 8-hour rate) and discharge profiles (1 minute to 24 hours)
- Container footprint, external dimensions, and terminal hardware
- Charge profile: 2.25 VPC float, final discharge 1.75 to 1.94 VPC
- Flame-retardant polypropylene container (UL94 V-0, 28% Limiting Oxygen Index)
- United States manufacturing line, factory, engineers, and QA teams
What changed (paperwork only):
- Label brand: “GNB” replaced with “Stryten”
- Document headers on spec sheets and manuals
- Customer service contact information
- Distributor paperwork (reseller letters re-issued under Stryten)
- Part number prefixes on procurement documents
The full technical picture is documented in the Stryten Absolyte AGP battery review.
Legacy GNB Absolyte to Stryten Absolyte AGP Cross-Reference
Companion cross-reference guide: holding a specific legacy part number right now? The step-by-step conversion path, where to find the number, what it tells you, and the 5-data-point worksheet that returns a confirmed match, lives in GNB Absolyte Part Number Cross-Reference: How to Find Your Stryten Absolyte AGP Replacement Model.
Legacy GNB Absolyte part numbers map directly to current Stryten Absolyte AGP equivalents. The cells in every row below are physically and electrically interchangeable with the legacy GNB part they replace: identical footprint, terminal geometry, AGM construction, charge behavior, and capacity profile.
| Legacy GNB Part Number | Current Stryten Absolyte AGP Equivalent | Module Configuration | Typical Application |
|---|---|---|---|
| 1-100G93 / 1-100A93 | Stryten Absolyte AGP 100A93 equivalent | 100 Ah series, 3-cell module | Telecom -48VDC plants |
| 1-100A87 | Stryten Absolyte AGP 100A87 equivalent | 100 Ah series, 3-cell module | Telecom and data center UPS |
| 1-100A45 | Stryten Absolyte AGP 100A45 equivalent | 100 Ah series, 3-cell module | Data center UPS, utility |
| 6-50G07 / 6-50A07 | Stryten Absolyte AGP 6-50A07 equivalent | 600 Ah series, 6-cell module | Data center, utility substation |
| 6-90A07 | Stryten Absolyte AGP 6-90A07 equivalent | 900 Ah series, 6-cell module | Utility substation, large UPS |
The legacy G-series and A-series families both map to the current Absolyte AGP line. If your exact legacy part number is not listed, it almost certainly still has a current equivalent. Send the nameplate to Tom and he will confirm the match against the Stryten cross-reference. The oil and gas GNB to Stryten cross-reference covers wellsite and SCADA configurations, and the GNB Absolyte GP replacement guide walks the broader part family.
How to Verify Authentic Stryten Absolyte
Confirm you are buying genuine, current-production Stryten Absolyte through four checks. The brand transition created an opening for gray-market and aged stock, so verification protects both your warranty and your uptime.
- The label: current cells carry Stryten Energy branding. Legacy GNB-labeled stock still in a warehouse may be years old, which erodes the 20-year design life clock before the string ever sees a load.
- The distributor: buy from an authorized Stryten distributor that can produce a signed authorization letter. Read the authorized Stryten distributor verification guide for the full vetting checklist.
- Certificate of origin: request documentation confirming US manufacture and the production date.
- Date-verified inventory: confirm the manufacture date so you are not buying cells that have aged on a shelf.
Specification and procurement detail is collected in the CPBS battery specifications and procurement guide.
The Authorized Distributor Landscape and Where CPBS Fits
Stryten Energy (stryten.com) sells industrial Absolyte through a network of authorized distributors, and CPBS is one of them. CPBS is authorized as a Stryten Energy reseller per a signed authorization letter from Eric Nordhoff, Stryten Zone Manager East, covering the complete Stryten Essential Power line including Absolyte.
Four things distinguish CPBS on a GNB-to-Stryten supply question:
- Signed reseller authorization available as attachable proof for procurement and audit files.
- ATS heritage: founded 1981, ISO 9001 certified, Chicago based, with 40-plus years of electronics expertise behind the battery division.
- Tom Kierna lived the transition: 15 years at GNB and Stryten means legacy part-number and warranty-status questions get a firsthand answer, not a guess.
- Primary-source documentation hosted in one place: CPBS hosts the three Stryten authority PDFs under permanent URLs and references them in every quote.
That documentation cluster is already cited in Google AI Overviews on authorized-distributor queries, which is why this supply guide extends the same authority to brand-availability questions.
Applications: Telecom, Data Center, Utility, Oil and Gas, and Government
Stryten Absolyte AGP serves every application legacy GNB Absolyte served. The compliance pedigree carried over with the design: UL Recognized, Telcordia GR-4228, NEBS Level 3 in certain configurations, seismic qualification (IEEE 693-2005, IBC 2018), and DOT 49 CFR 172 / UN 2800 shipping.
- Telecom: central office and -48VDC plants, front-terminal and hot-swap configurations.
- Data center: UPS strings, parallel cabinets, sized per IEEE 485-2020.
- Utility substation: control and relay backup, seismic-anchored in Zone 4 jurisdictions.
- Oil and gas: SCADA and wellsite backup in hazardous-location installations.
- Government and defense: Buy American compliant, with IEEE-535 Class 1E variants available.
For the broader flooded lineup that runs alongside Absolyte AGP, the Stryten E-Series selection guide covers the MCT, MCX, NXT, H1T, and PDQ flooded products.
Lead Times and Ordering
Stryten Absolyte AGP runs 8 to 10 weeks domestic from the US factory. Plan procurement against that window so a string at end of life is not running on borrowed time.
- Domestic (US): 8 to 10 weeks from the US factory.
- International: longer, typically with 50% down at order and the balance at port of entry.
- Custom seismic configurations: add engineering sign-off time.
CPBS confirms current lead time on every quote against Stryten production scheduling at the time of order. If a legacy string is already showing end-of-life signals, start the conversation early so the order clock and the battery’s remaining service life do not collide.
Warranty Status on Legacy GNB Absolyte
Factory warranty terms transferred with the rebrand. Legacy GNB Absolyte units remain covered under their original factory terms, and CPBS routes any legacy warranty question through the Stryten warranty desk. Because Tom Kierna worked inside both GNB and Stryten, he can advise on warranty conversion for an in-service legacy string and on whether a claim is best handled as a warranty matter or a planned replacement.
When a legacy string does reach end of life, spent GNB Absolyte cells route through Stryten’s closed-loop recycling network under DOT 49 CFR 172 and UN 2800, with lead-acid recovery running approximately 99 percent. When you are ready to plan the swap itself, the companion field guide to replacing GNB Absolyte batteries in telecom and data center facilities walks the full procedure step by step.
🎯 Bonus Step. Attach the three Stryten primary-source documents to your procurement file. Together they answer every legitimate availability, substitution, and warranty question on a GNB-to-Stryten supply decision.
- Stryten E-Series Branding Change Letter: the March 2023 rebrand announcement that formally renamed the GNB-branded industrial portfolio to Stryten.
- CPBS / ATS Stryten Energy Authorized Reseller Letter: the signed reseller authorization from Stryten Zone Manager East Eric Nordhoff confirming CPBS as an authorized Stryten channel.
- Manufacturer’s Declaration of Design Continuity: the August 2023 declaration signed by Stryten Director of Engineering Michael Berger stating that design, engineering, and manufacturing remain unchanged from GNB to Stryten.
CPBS hosts all three under permanent URLs and references them in every Absolyte quote.
