Will the Dyson replacement battery 974815-01 (V8 / V7 Advanced / Car+Boat) work with the Dyson V8 cordless stick vacuum (star pre-filter version, SV25)?
Yes. Both use Dyson V8 replacement battery (974815-01).
Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.
Why
- ✓ Both use Dyson V8 replacement battery (974815-01).
Good to know
- Dyson says the V8 range has used three different batteries over its life; check the first three characters of the serial number (under the machine or on the battery) on Dyson's V8 battery page before buying.
- Names like 'V8 Absolute' and 'V8 Fluffy' were sold in both star and pinch pre-filter versions, so the name alone does not tell you which filter fits; the battery 974815-01 covers both.
- Dyson's 974815-01 compatibility list does not name the original Dyson V7 (SV11); the V7 has its own battery (968670-06).
- Not interchangeable with V10, V11, V12, V15 or Gen5 batteries.
