Buyers who need a different fit

This pack suits owners of the listed Shark hand vacuums who want a direct replacement with overcharge, over-discharge, over-voltage and short-circuit protection. It will not fit other Shark models or vacuums from other brands that use a different connector or voltage.

Voltage and capacity

The decisive specification is the 18.0V 3000mAh rating, which must match the original battery label on your device. Confirm the XBT779 part number before ordering to ensure correct compatibility.

Questions about this item

How long will the 3000mAh 18.0V Ni-MH pack run before the over-discharge protection cuts power?

The built-in protection stops discharge once the pack reaches its safe lower limit, so the vacuum will shut off instead of draining the cells below that point.

Does the 908.7 g battery get hot during a full day of cleaning?

The pack includes over-voltage and short-circuit safeguards that limit heat build-up, and the Ni-MH chemistry runs cooler than older chemistries under continuous load.

My Shark hand vac uses part number XBT779 — will this SV780 replacement fit without an adapter?

Yes, the SV780 is built to the exact dimensions of the original XBT779 cell, so it slides straight into the SV780, VX33 and Pet Perfect II models.
