Dyson's current replacement battery for V8 stick vacuums (both star and pinch pre-filter versions), V7 Advanced and Car+Boat.
- 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).
