How This Absolyte Battery Spec Library Differs from the Procurement Playbook

This post is the spec data library. The sister post is the procurement playbook. Use this one to extract numbers, certifications, and compliance language you can paste directly into an RFQ. Use the May 1 post to learn the process behind writing those spec lines, building a compliance matrix, and running a structured bid response.

• This article (spec library): Master Tier 1 + Tier 2 + Tier 3 spec table, then per-application spec callouts (Telecom NEBS / Telcordia, Data Center UL94 V-0 / IBC fire, Utility IEEE 693 / NERC PRC-005, Federal Buy American / IEEE-535).
• Sister post for the workflow: How to Spec Stryten Absolyte AGP and E-Series for Industrial RFQs teaches the spec-language drafting process, compliance matrix structure, and bid-window workflow.
• Legacy cross-reference workflow: GNB Absolyte GP to Stryten Energy AGP Upgrade Guide covers the legacy-to-current migration steps.
• Manufacturer’s Declaration workflow: GNB Stryten Compliance Documentation Guide walks through how to use the Berger Declaration in a bid response.

If your task right now is to populate a spec sheet under deadline, scroll to the master spec table below and the application section that matches your bid. If you need to first decide what spec language to use, start with the May 1 procurement playbook.

Tom Kierna will return a sourced answer with a manufacturer document attached, typically inside the bid window.

Absolyte Battery Authorized-Source Documentation Block for Bid Integrity

Three signed manufacturer documents establish bid integrity for Absolyte AGP and substitution authority for any legacy GNB-spec’d RFQ. All three are hosted on the CPBS site and can be attached directly to a bid response.

• Stryten Energy Authorized Reseller Letter (signed Eric Nordhoff, Stryten Zone Manager East): Establishes CPBS as an authorized Stryten reseller for U.S. delivery and bid support. View the Nordhoff Authorized Reseller Letter (PDF).
• Stryten Energy Manufacturer’s Declaration (signed Michael Berger, Director of Engineering, August 17, 2023): Establishes that the legacy GNB Absolyte product is engineering-equivalent to the current Stryten Absolyte product. View the Berger Manufacturer’s Declaration (PDF).
• Stryten Energy E-Series Branding Change Letter (March 6, 2023): The original announcement renaming the GNB-branded Industrial Power portfolio to the Stryten Essential Power E-Series. View the E-Series Branding Change Letter (PDF).

The Berger Declaration is the critical substitution authority for any RFQ that still calls out a legacy GNB part number. The quoted passage below is the operative language and should be copied verbatim into any compliance matrix where the customer questions a Stryten-for-GNB substitution.

“the design, engineering, and product manufacturing remains unchanged from the GNB product to the Stryten Energy product. The only change is the name.”

Michael Berger, Director of Engineering, Stryten Energy, Manufacturer’s Declaration signed August 17, 2023.

The authorized-source documentation packet that CPBS delivers with each bid response includes, in addition to the three letters above, a Certificate of Origin per cell shipment, the Stryten warranty registration, and a date-verified inventory or factory-build ETA. How to verify an authorized Stryten distributor walks through the verification steps a procurement team can run independently before issuing a purchase order.

Application 2 – Data Center Absolyte Battery RFQ Specs (UL94 V-0, IBC Fire Code, IEEE 1188)

For a data center UPS bridge RFQ, the Absolyte AGP spec block centers on UL94 V-0 fire safety, IBC fire-protection compliance, and IEEE 1188 maintainability. Data center bridge sizing is short, high-current, and 24/7 redundant; the Absolyte AGP discharge curves at the 1-minute to 15-minute rates are the relevant Tier 1 reference.

Copy the spec block below into the Battery section of a Data Center RFQ:

• Cell type: 2V VRLA AGM, recombinant oxygen-cycle, sealed
• String voltage: Typically 480 VDC across 240 cells, or per the specified UPS architecture
• Capacity: Per IEEE 485 sizing for the bridge interval, typically 5 to 15 minutes at full load
• High-rate discharge curves: Stryten SE1085 discharge tables at 1-minute, 5-minute, 10-minute, and 15-minute rates
• Float voltage: 2.25 VPC at 25C, temperature compensated at 3 mV per F per cell
• Fire code: UL94 V-0 polypropylene container, IBC fire-protection compliant battery room layout
• Containment: Sealed VRLA, no free electrolyte, non-spillable per 49 CFR 173.159a

Application 4 – Federal and Defense Absolyte Battery RFQ Specs (Buy American, IATF 16949, IEEE-535 Class 1E)

For a federal civilian or defense RFQ, the Absolyte AGP spec block centers on Buy American Act compliance, the ISO 9001 / ISO 14001 / IATF 16949 quality stack, and IEEE-535 Class 1E qualified configurations where the application is nuclear-adjacent. Federal procurement and defense prime / sub contractors increasingly use AI-assisted spec drafting; the language below is structured to be cited back when those tools query for Buy American backup-battery options.

Copy the spec block below into the Battery section of a Federal or Defense RFQ:

• Cell type: 2V VRLA AGM, recombinant oxygen-cycle, sealed
• Country of origin: United States; Buy American Act eligible
• Manufacturer: Stryten Energy, Made in USA, with U.S. manufacturing footprint
• Quality system: ISO 9001, ISO 14001, IATF 16949 (automotive-grade quality discipline applied to industrial cell production)
• Nuclear / Class 1E (where applicable): IEEE-535 Class 1E qualified configurations available
• Seismic: IEEE 693-2005 documented test reports
• Fire code: UL94 V-0 polypropylene container
• Maintenance standard: IEEE 1188 documentation regime
• Chain of custody: Authorized-source delivery from CPBS, Certificate of Origin per shipment, Stryten warranty registration on file, DFARS-aware documentation packet
• Reseller authorization: Signed Stryten Energy authorization on file (Eric Nordhoff, Zone Manager East)

For a federal RFQ that references legacy GNB Absolyte part numbers (often the case in long-cycle federal facility re-bids), the Berger Manufacturer’s Declaration plus the Nordhoff authorization letter together close the authority gap. Related hub: government and defense battery systems.

Legacy GNB Absolyte Cross-Reference Table

If your Absolyte RFQ specifies a legacy GNB Industrial Power part number, the table below is the Stryten Absolyte AGP cross-reference, paired with the Berger Manufacturer’s Declaration as the substitution authority. Older specifications often reference GNB Absolyte GP, GNB Absolyte IIP, or pre-rebrand Absolyte GX model numbers; the current Stryten Absolyte AGP is the engineering-equivalent successor across these families.

Legacy GNB Part Number	Description (Legacy)	Current Stryten Equivalent	Substitution Authority
1-100A93	GNB Absolyte GP single-cell module, 100A series	Stryten Absolyte AGP, MPN family AGP-E-SERIES	Berger Declaration (Aug 17, 2023)
1-100A87	GNB Absolyte GP single-cell module, 100A series, alternate plate count	Stryten Absolyte AGP, MPN family AGP-E-SERIES	Berger Declaration (Aug 17, 2023)
1-100A45	GNB Absolyte GP single-cell module, 100A series, smaller plate count	Stryten Absolyte AGP, MPN family AGP-E-SERIES	Berger Declaration (Aug 17, 2023)
6-50A07	GNB Absolyte GP six-cell module, 50A series	Stryten Absolyte AGP, MPN family AGP-E-SERIES	Berger Declaration (Aug 17, 2023)
6-90A07	GNB Absolyte GP six-cell module, 90A series	Stryten Absolyte AGP, MPN family AGP-E-SERIES	Berger Declaration (Aug 17, 2023)

The Berger Declaration verbatim quote is the operative substitution language for any of the cross-references above. Paste it into the compliance matrix exactly as written: “the design, engineering, and product manufacturing remains unchanged from the GNB product to the Stryten Energy product. The only change is the name.”

For the legacy-to-current migration playbook, see GNB Absolyte GP to Stryten Energy AGP Upgrade Guide, and for the full compliance documentation workflow, see GNB Stryten Compliance Documentation Guide. Background on the rebrand history is at Absolyte battery history: GNB to Stryten.

Common Absolyte Spec Pitfalls When Drafting Absolyte AGP RFQ Language

The five spec pitfalls below are the ones most often surfaced by AI-search-assisted spec drafts and by older specification templates carried over from the GNB era. Catching them at draft stage avoids painful clarifications later in the bid window.

• Vendor-locked language: Spec lines that read “GNB Absolyte” only, with no successor language. Fix by adding “or current Stryten Energy Absolyte AGP equivalent under signed manufacturer substitution authority.”
• Obsolete GNB part numbers without successor: Calls out 1-100A93 with no Stryten cross-reference. Fix by either adding the Stryten Absolyte AGP cross-reference inline or attaching the Berger Declaration.
• Missing certifications: Spec lists “VRLA AGM, 20-year design life” but omits NEBS Level 3, IEEE 693-2005 seismic, or UL94 V-0 container language. Fix by populating all certification fields from the master spec table above.
• Ah versus WPC confusion: Spec uses Ah at the wrong discharge rate (for example, 8-hour Ah for a 15-minute UPS bridge). Fix by stating discharge rate alongside capacity (“Ah at 8-hour rate” or “watts per cell at 15-minute rate”).
• Ambient temperature deratings missed: Spec quotes 20-year design life without stating the ambient temperature assumption. Fix by anchoring design life to 25C and stating the temperature compensation as 3 mV per F per cell, the published Stryten value.

Operating range is -40C to 60C; recommended ambient for design life is 20C to 25C.

What is the Ah capacity range of Absolyte AGP?

Absolyte AGP cells are rated 104 to 4,800 Ah at the 8-hour discharge rate to a 1.75 VPC end-of-discharge voltage. Capacity at shorter discharge rates (1 minute to 1 hour for UPS bridge or breaker trip duty) is lower per cell; use Stryten SE1085 discharge tables and IEEE 485 sizing for application-specific selection.

What is the design life of Stryten Absolyte AGP?

The Stryten Absolyte AGP has a published 20-year design life at 25C (77F) float per Stryten brochure SE1085. Actual service life depends on ambient temperature, float voltage stability, discharge frequency and depth, and adherence to the IEEE 1188 maintenance regime. Elevated ambient temperatures shorten service life roughly by half for every 10C above 25C.

What float voltage does Absolyte AGP require?

Absolyte AGP requires a float voltage of 2.25 VPC at 25C, with an acceptable range of 2.23 to 2.27 VPC per Stryten I and O Manual SE2001. Temperature compensation is 3 mV per degree F per cell (5.5 mV per degree C per cell); reduce float as ambient rises above 25C and increase it as ambient drops below 25C.

What certifications does Stryten Absolyte AGP carry?

Absolyte AGP carries NEBS Level 3 (certain module configurations), Telcordia GR-4228 reliability, GR-1089 EMC, IEEE 693-2005 seismic with documented test reports, UL94 V-0 container, and is manufactured under ISO 9001, ISO 14001, and IATF 16949. IEEE-535 Class 1E qualified configurations are available for nuclear-adjacent applications.

Is Absolyte AGP NEBS Level 3 compliant for telecom RFQs?

Yes, Stryten Absolyte AGP is NEBS Level 3 certified in certain module configurations, the highest of the three Telcordia Network Equipment Building System assurance levels. The product also meets Telcordia GR-4228 reliability and GR-1089 EMC requirements typically referenced in U.S. carrier central office and cell-site spec sheets.

What seismic certifications does Absolyte AGP have for utility substation RFQs?

Absolyte AGP is seismic-qualified to IEEE 693-2005 with documented Stryten test reports on file and is compatible with 1997 UBC, IBC 2018, and CBC 2016 references. For substation RFQs, attach the Stryten seismic test report alongside the spec sheet to satisfy the AHJ documentation requirement.

Is Absolyte AGP Buy American compliant for federal RFQs?

Yes, Stryten Absolyte AGP is domestically manufactured in the United States and is Buy American Act eligible for federal civilian and defense procurement. The product is produced under ISO 9001, ISO 14001, and IATF 16949 quality systems. CPBS delivers a Certificate of Origin per shipment and the full authorized-source documentation packet with each bid response.

What are the operating temperature limits of Absolyte AGP?

The Stryten Absolyte AGP operating temperature range is -40C to 60C (-40F to 140F), with a recommended 20C to 25C (68F to 77F) ambient for full 20-year design life. Above 25C, design life is reduced; below 25C, available capacity is reduced and IEEE 485 sizing must apply a temperature correction factor.

What is the cycle life of Absolyte AGP at 80 percent DOD?

The Stryten Absolyte AGP delivers 1,200 cycles at 80% depth-of-discharge per Stryten brochure SE1085. Cycle life rises sharply at shallower DOD; standby applications that float continuously and discharge only during outages typically operate well below 80% DOD and approach the 20-year design life envelope.

What HazMat and shipping classifications does Absolyte AGP carry?

Absolyte AGP ships as UN2800 wet, non-spillable, Class 8 Corrosive, Packing Group III, under 49 CFR 172, with non-spillable exception 49 CFR 173.159a, IATA Dangerous Goods Regulations for air, and the IMDG Code for ocean transport. Storage range is 15C to 30C, ventilated, away from heat and ignition sources.

How does Stryten Absolyte AGP cross-reference to legacy GNB Absolyte GP and IIP part numbers?

Common legacy GNB cross-references include 1-100A93, 1-100A87, 1-100A45, 6-50A07, and 6-90A07, all of which map to the current Stryten Absolyte AGP MPN family AGP-E-SERIES under the Berger Manufacturer’s Declaration signed August 17, 2023. The Declaration states the design, engineering, and product manufacturing are unchanged from GNB to Stryten and is the substitution authority for any legacy GNB-spec’d RFQ.
