Assessment as of July 10, 2026
Section 4865's first hard deadline is January 1, 2028, covering new acquisition programs. The triggering signal for this assessment is an absence: no public implementation artifact has appeared since the statute's own DFARS revision window passed.
The FY2025 NDAA was enacted approximately December 20, 2024. Section 4865 directs DFARS revision within 180 days of enactment, yielding an approximate mid-June 2025 target. That window closed over a year ago. No DFARS clause, no eCFR entry, no acquisition.gov guidance, no contracting-officer flowdown language for Section 4865 battery-sourcing compliance has appeared in any checked public route as of July 10, 2026. Targeted searches of Defense News, Breaking Defense, National Defense Magazine, and C4ISRNET for April through July 2026 coverage of 4865 implementation returned nothing in checked routes. The statute is fully specified. So is the waiver architecture. But the connective tissue between them, the mechanism by which a contracting officer would actually enforce the 95% non-FEOC functional-cell-component cost threshold, does not visibly exist.
Proof-Stack Completeness
Supplier count alone understates the problem. The gap is better measured by proof-stack completeness: the layered evidence chain a contracting officer will eventually need to determine compliance. That chain requires at minimum five layers:
- Cell-origin documentation
- Component-cost-origin tracing to the 95% non-FEOC threshold
- FEOC technology-license status verification
- Qualification evidence (FAT, QPL, or equivalent)
- Recurring production procurement at compliant volume
No visible domestic or allied supplier satisfies all five layers in the public record.
| Supplier | Cell Origin (1) | FEOC Cost Tracing (2) | License Verification (3) | Qualification (4) | Production Volume (5) |
|---|---|---|---|---|---|
| EnerSys / Bren-Tronics | Visible (10-K) | Not visible | Not visible | Not visible | Not visible |
| Ultralife | Ambiguous — uses "qualified cell manufacturers" | Not visible | Not visible | Not visible | Not visible |
| Korean makers (LGES, Samsung SDI, SK On) | Allied-nation status partially relevant | Potentially addressable | Not visible | Zero artifacts | Zero artifacts |
| QPL-32565 | Active since Jan 2017 | — | — | No public product rows | — |
EnerSys/Bren-Tronics is the strongest domestic asset following the $206.4M Bren-Tronics acquisition completed July 2024. The FY2026 10-K establishes domestic manufacturing capability. It does not reference Section 4865, does not disclose a compliance file, and does not publicly confirm MIL-PRF-32565 qualification for 6T Li-ion.
Ultralife Corporation reported $16.9M in Q1 2026 government/defense revenue, 36% of total quarterly revenue. Its FY2025 10-K states it markets Li-ion batteries "comprising cells manufactured by qualified cell manufacturers." That language raises the FEOC-origin question for its cell supply chain rather than resolving it. No Ultralife filing references MIL-PRF-32565, QPL-32565, or Section 4865.
Korean makers have zero public defense qualification artifacts. Allied-nation status potentially addresses layer two (FEOC cost-origin tracing) but does nothing for layer four (FAT/QPL qualification). These are separate gates operating on separate timelines, and no Korean maker has a visible FAT pathway for any U.S. military battery specification. Earnings references to "defense applications" remain unconfirmed positioning, not evidence of qualified supply.
QPL-32565 is active. MIL-PRF-32565 is active. No qualified manufacturer is visible in public QPL metadata; restricted entries may exist but are not assessable from public sources. Nine years without a publicly visible qualified supplier is a data point about the 6T lane's readiness for any compliance overlay.
The compliance repository due January 1, 2027 defines "covered sourcing requirements" as §§4862–4864 and Title 41 Chapter 83. Section 4865 is not listed. Batteries may be excluded from the reporting infrastructure by what appears to be a drafting gap.
Nothing Moved, and That Is the Signal
The Army SBIR A254-P050 closed for Phase I applications on May 13, 2026. No award notice has appeared in checked public routes as of this writing. The SBIR.gov API was returning HTTP 429 during this check, so the finding is "no award surfaced," not "no award exists." Typical Phase I award lag may explain the absence.
A254-P050 is a Phase I solicitation, up to $250K, targeting thermal-runaway mitigation and battery prognostics for MIL-PRF-32565 6T batteries. These are feature gaps. No active MIL-PRF-32565 production solicitation or delivery-order contract appeared on SAM.gov in this check. Phase I is exploratory interest. Only Phase III or follow-on production contracts indicate procurement volume. The 6T lane has the former and none of the latter.
The Requalification Drag
Compliance remediation operates as a second derivative on qualification velocity. A program currently using cells with FEOC supply-chain exposure must swap cells or materials to satisfy 4865. Under Army FAT rules, any change in cell design, material, process, or facility requires a new first article. The act of achieving compliance restarts the qualification clock.
The resulting delay is estimated at 18–36 months. This is practitioner judgment based on SBIR phase durations and FAT process structure, not a published DoD average. No public DoD source provides a standard FAT completion timeline for battery qualification.
Programs closest to compliance are those that never had FEOC exposure. Programs that need to remediate face the longest path. The waiver channel accommodates this dynamic without shortening it. Statutory waiver architecture: SecDef authority, delegable only to USD(A&S), one-year duration, system-or-battery-specific, no per-waiver public disclosure required, congressional briefing by December 1, 2028. No public waiver request mechanism has been specified.
2029 and 2031 Status Lines
January 1, 2029 (standard batteries/NSN items): No significant change. The same proof-stack gaps apply with twelve additional months of runway. The QPL-32565 vacancy is most directly relevant here. No new signal.
January 30, 2031 (existing programs of record): No significant change. The RDT&E exemption covers current pipeline activity but not production procurement. The longer timeline helps only if implementation machinery and qualification pipelines begin moving. Neither is visible.
Blue UAS and Battery Compliance
Blue UAS platform certification satisfies platform-access evidence but leaves battery-compliance evidence unaddressed. A drone on the cleared list may contain cells with FEOC supply-chain exposure. The companion summary covers this distinction in depth.
Eighteen months remain. The statute specifies what must be true. The waiver architecture specifies what happens when it cannot be. Between those two structures sits the space where contracting officers, program managers, and suppliers will actually operate. As of July 10, 2026, that space is empty in the public record, and the waiver channel appears to be the default operating model.
- Section 836 repository scope: The compliance repository due January 1, 2027 lists §§4862–4864 and Title 41 Ch. 83 as "covered sourcing requirements" but omits §4865, which could exclude batteries from the only mandated cross-program audit mechanism.
- Blue UAS battery provenance: EO 14307 directs monthly updates to the Blue UAS Cleared List and DCMA transition is underway, but no public list metadata exposes battery supplier, cell origin, or component-cost fields.
- A254-P050 award posting: The Army SBIR topic for 6T Li-ion battery technical gaps closed May 13, 2026 and Phase I awards have not yet appeared in checked public routes, though SBIR.gov API maintenance and typical posting lag may account for the delay.
- First public waiver artifact: No Section 4865 waiver request, template, SAM.gov modification, or Federal Register notice has surfaced in checked public routes, making the first visible waiver action the clearest signal of how DoD intends to bridge the mandate-supply gap.
