Questions about this item

How do I install the 7.2V 3000mAh pack into my Shark vacuum, and what step do people often miss?

Slide the pack into the battery compartment until the latch clicks; the step many miss is fully seating the connector so the contacts align with the 7.2V terminals.

What maintenance or replacement will the Ni-MH 3000mAh battery need later?

Ni-MH cells self-discharge; store at half charge and recharge every three months if unused, and replace the pack when run-time falls below your cleaning needs.

What limit appears first during sustained use of the 21.6Wh pack?

The 3000mAh capacity determines run-time; under continuous high-power cleaning the pack will hit its voltage cut-off before thermal limits become an issue.
