- Use only owner-access points and maintenance actions documented for the exact machine code.

Confirm the V7 handheld configuration
V7 handheld (HH11) is a bagless handheld body with direct-fit cleaning tools. Cataloged variants include V7 handheld with HEPA post filter, V7 handheld without HEPA post filter. The verified owner-service profile identifies it as the Dyson V7 HH11 dedicated handheld family. Match the machine code and serial label before ordering a filter, bin, direct-fit tool, battery where owner-replaceable, 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 battery pack specified for the exact machine code listed for V7 handheld (HH11). Screw-retained HH11 battery replaced only as a complete exact-match pack. Do not choose by retail family name or physical appearance alone.
Remove the old complete battery
Power the machine off, disconnect the charger, press the documented battery release, and withdraw the complete click-in or swappable pack without forcing it.
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.
