Direct replacement for Shark Ion robots

This 14.4 V lithium-ion pack replaces the original RVBAT850 cell used in Shark Ion robot vacuums. It delivers 3600 mAh capacity and a two-prong connector that matches the factory layout. The physical dimensions are 69.50 by 37.20 by 37.20 mm so it seats in the same compartment. Built-in circuitry guards against over-charge, over-discharge, over-current, over-voltage, over-load, over-heating and short circuits.

Suits owners of listed Shark Ion models

The pack fits Shark Ion robots carrying model numbers R75, R76, RV85, RV1000, RV1001, RV101AE, RV2001, RV2001WD, R3Z and R4Z. Buyers whose robot uses a three-prong battery connector cannot use this unit. Units that require a different voltage or form factor should look elsewhere.

Two-prong connector requirement

The single specification that decides compatibility is the two-prong plug on the battery. If the original battery in the robot shows a three-prong connector this pack will not connect. Verify the connector style before ordering.

Questions about this item

What comes with the BFKK RVBAT850 battery and do I need any extra parts?

The replacement battery ships as a single unit with a 2-prong connector. No additional cables, screws or tools are required for installation.

My robot is listed as an RV1001AE — is the 14.4 V 3600 mAh version the correct one?

Yes. The 14.4 V 3600 mAh (51.84 Wh) pack matches the original RVBAT850 specification for the RV1001AE, R75, R85, S87, RV751, RV1000, RV2001, RV2001WD, R3Z and R4Z models.

How does the 3600 mAh capacity translate to actual cleaning time once the battery is fitted?

The 3600 mAh rating restores the robot to its factory runtime; expect the same cleaning duration you had with a new original RVBAT850 pack under identical floor conditions.
