Dyson V12 replacement battery FAQ
How long does the Dyson V12 battery last per charge?
In Eco mode, around 45 minutes with a standard capacity pack. Higher-capacity batteries offer longer runtimes. Using Boost mode can significantly reduce runtime.
Why is my Dyson V12 battery draining quickly?
An ageing battery, frequent use of Boost mode or storage in high temperatures can shorten runtime. A higher-capacity replacement battery offers more power for longer cleaning sessions.
Can I change the Dyson V12 battery myself?
Yes. The Click-in mechanism allows tool-free replacement at home.
Will a V11 or another V12 battery fit my Dyson V12?
Sometimes, yes. If the battery shares the Click-in design and voltage, it may be compatible. Always verify the part number (e.g. 970425-01, 970938-01, 355983) and battery type (Click-in) before buying.
