Frequently Asked Questions
How often should I replace the Dyson V15 Detect battery pack?
Dyson suggests replacing the V15 Detect battery pack Every 2-3 years under normal use — sooner with pets or daily heavy use. Signs it's due: Short runtime, not charging.
How long should the V15 Detect battery last, and why did my runtime drop?

Do I have to buy the genuine Dyson part, or will a compatible one work?
Yes — a compatible (aftermarket) battery pack works well in the Dyson V15 Detect as long as it's made for this exact model. Look for 4.3+ stars with plenty of reviews, and confirm the listing names your exact model.
How much does a Dyson V15 Detect battery pack cost?
Compatible battery pack options for the Dyson V15 Detect start around $79.10. The prices in the table above are checked against Amazon regularly; multipacks usually cost less per unit.
