Battery options & usable capacity
Ford’s 2021 US technical sheet explicitly lists 68 kWh usable for Standard Range and 88 kWh usable for Extended Range. These are original-specification references, not current battery measurements.

|---|---|---|
| 2021 US Standard Range — 68 kWh usable | 68 kWh | Manufacturer · Source |
| 2021 US Extended Range — 88 kWh usable | 88 kWh | Manufacturer · Source |
Charging capability
Verify the installed charging equipment and the specification for the exact model year. Use a recorded session and the correct SoC window to judge whether charging meets your needs.
| Reference | AC limit | DC peak |

Battery warranty
The cited US sheet lists eight years or 100,000 miles for the battery system. Eligibility, capacity provisions and exclusions require the full original warranty; this headline is not a coverage confirmation.
Things worth checking before purchase
- Confirm Standard Range or Extended Range and the original model year.
- Check that the battery has not been replaced with a different specification.
- Ask for completed campaigns and outstanding service actions in writing.
- Keep advertised range separate from a recent consumption sample and diagnostic battery evidence.
Turn the evidence into a useful estimate
Collect a full-charge range estimate and recent battery-side consumption from matching conditions. Select the exact reference in the calculator. Where usable capacity is not verified, enter it from the appropriate documentation. Original specifications remain separate from any diagnostic figure supplied by the seller.
EVVerity estimates are informational and are not a substitute for a professional battery diagnostic or pre-purchase vehicle inspection.
