This genuine Dyson V7 battery is a direct replacement for SV11/V7 vacuum models. These batteries are original Dyson batteries unlike cheaper batteries that fail to work correctly. The battery is easy to replace and includes 4 new fastening screws to use when installing the battery.
For best results inspect your filter. Many times batteries fail prematurely because of improper maintenance. A poorly maintained filter will cause the vacuum to work harder and thus hotter damaging the battery's cells.
