The Dyson 206340 is a replacement battery pack for Dyson cordless vacuums. It is meant to restore runtime when the original pack no longer holds a charge or the vacuum will not start. It is a genuine Dyson part rather than a third-party cell, which matters for fit and for keeping the vacuum's charging behavior unchanged. Buyers should confirm the part number matches their model, since Dyson cordless batteries are not interchangeable across generations.

This is a replacement battery for Dyson cordless vacuums. It is meant for a vacuum that will not turn on, will not hold a charge, or has poor battery life.
Battery wear is a normal part of a cordless device's lifespan, and swapping in a new battery replaces one that is dead or dying.
