Instructions
How to complete this repair
- Bright flashlight
- Power the vacuum off, disconnect its charger, and remove a detachable battery only when the exact owner guide describes that action.
- Use only owner-access points and maintenance actions documented for the exact machine code.
- Do not use or charge a swollen, leaking, cracked, wet, punctured, unusually hot, or impact-damaged battery.
- Replace the complete genuine battery assembly only. Never open the pack or replace individual cells.
Confirm the V8 configuration
V8 (SV10 / SV10E / SV25) is a bagless cordless body with a wand and powered cleaner head fitted to this machine. Cataloged variants include V8 Animal, V8 Absolute, V8 Origin. The verified owner-service profile identifies it as the Original Dyson V8 cordless family. Match the machine code and serial label before ordering a filter, bin, wand, cleaner head, battery, or charger; a retail family name can cover incompatible hardware.
Confirm that the battery is the likely fault
Record runtime and charging indicators, confirm the matching charger and outlet work, clean dry external contacts, and let the battery reach normal room temperature. A no-power symptom can also come from the charger, controls, airflow protection, or main body.
Match the replacement to the machine code
Order a complete machine-code-specific battery pack listed for V8 (SV10 / SV10E / SV25). Screw-retained battery with generation-specific fit; SV10E/SV25 and earlier V8 parts must be selected through Dyson's configuration selector. Do not choose by retail family name or physical appearance alone.
Remove the old complete battery
Power the machine off, disconnect the charger, and follow the exact owner guide to remove only the screws securing the complete external battery pack. Do not remove body or pack screws not identified in that procedure.
Install, charge, and test
Seat the exact replacement using the reverse documented method, confirm every latch or owner battery-cover screw is secure, and charge it with the matching charger. Make one normal test and stop for heat, odor, swelling, an error, or continued short runtime.
