approximately 30 battery factories are currently planned, being constructed, or operational in the United States alone; 13 of them are expected to open by 2025.

The '13 by 2025' figure matches the US DOE's December 2021 projection of 13 new battery-cell gigafactories by 2025 (reported by Electrek), reprinted without attribution, so under D30 it reads as a quoted third-party figure. Independently, D23 fails: the edition names no list for the '~30 factories', so the scope cannot be fixed, and no public tally of US battery-cell plants operational at end-2025 on a defined list was found (looked for DOE VTO Fact of the Week updates, Argonne Li-ion supply-chain database summaries, news tallies).
Test: D16 numeric rule on a count: number of those US battery factories open by 31 Dec 2025 within 10% of 13 = hit, within 25% = partial.
Grader B: hit
Dallas Fed (March 2026): 12 plants operating and 23 at various stages of construction - i.e. ~35 total, matching the edition's ~30 frame. 13 vs 12: error +8% -> hit. Alternative reading (the DOE's 2021 list of 13 NEW plants all open by 2025) would be a miss: Ford BlueOval City TN, BlueOval SK Kentucky 2, VW Chattanooga, a GM-LG fourth plant were not open and Stellantis-LG is in Canada. The edition does not cite the DOE list, so the operating-count reading is graded.
Test: Count of operating US battery (cell) gigafactories at end-2025 within 10% of 13 (D16 numeric, count).
