CPSC proposes making UL battery standards mandatory
The US Consumer Product Safety Commission published a notice of proposed rulemaking, not a final rule, to make lithium-ion micromobility electrical systems meet modified UL standards. Do not treat this as already in force.
Federal Register document 2026-12749 (91 FR 38162, CPSC Docket CPSC-2025-0012, RIN 3041-AE10) published June 24, 2026. Written comments were due August 24, 2026. The docket page showed comments no longer being accepted (62 comments). There is no final rule or effective date in this NPR.
What the proposal would cover
- E-bikes, to a modified UL 2849:2020
- Personal e-mobility devices including e-scooters, to a modified UL 2272:2024
- User-replaceable LEV battery packs, to a modified UL 2271:2023
- Conversion-kit components and aftermarket chargers as described in the NPR
CPSC would require those systems to comply with the applicable voluntary standards with modifications (examples in the NPR include tamper-resistant enclosures, a post-discharge charge test, a reverse-polarity test, and expanded labeling). The incident backdrop cited in the NPR: 227 unique incidents 2019–2023, including 39 fatalities.
For buyers. Keep treating UL 2272 (kick scooters) and UL 2849 / 2271 (e-bikes) as the certification language to check on a product page. Federal mandatory adoption is proposed, not yet the law.
