Which Dyson vacuums does this battery fit?

It is listed for Dyson cordless vacuums under the CS-DYC700VX part number. Check your vacuum's model and original battery part number against this code before buying, since Dyson uses different packs across its cordless lines.

Is this a genuine Dyson battery?

No. It is a Cameron Sino engineered replacement pack, not a Dyson-branded part. Dyson's own warranty does not cover third-party batteries.

How long will it run on a charge?

No runtime or capacity figure is published for this pack. Expect performance in the range of the original Dyson battery it replaces, with runtime falling as the pack ages.

How hard is it to install?

It is designed as a drop-in replacement, so installation is a direct swap of the old pack. No special tools beyond what removing the original battery requires.

Will it work with my Dyson charger?

It is built as a replacement for the Dyson cordless battery, so it is intended to charge with the vacuum's existing charger. Confirm the part number matches your model first.

Is it worth it versus a Dyson replacement?

If your vacuum still cleans well and only the battery has faded, a third-party pack is a cheaper way to keep it running. If you want Dyson-backed warranty and guaranteed fit, buy the branded pack.
