Replacement Battery for Shark Ion Robots

This 3600mAh lithium battery replaces the RVBAT850 pack in compatible Shark Ion robot vacuums. It fits models RV1001AE, RV700_N, RV720_N, RV725_N, RV750_N, RV761, RV850, RV850BRN, RV850C, RV850WV, RV851WV, RV871, RV871C, R75, R85 and RV1000S. Installation requires removing two screws and swapping the connector. Built-in protection circuits guard against short circuit, over-current, over-charge, over-voltage and overheat.

Two-Prong Connector Limits Compatibility

The battery uses a 2-prong connector, so it will not work with robots that use the 3-prong RVBAT700 pack. Models RV700, RV720, RV750 and RV755 are explicitly excluded. Buyers must verify both the robot model and the original battery part number before ordering.

Check Model and Connector Before Ordering

Confirm that your robot is listed above and that the existing battery shows part number RVBAT850 with a 2-prong plug. If the original battery has a 3-prong connector or carries the RVBAT700 label, this pack is not compatible. When uncertain, compare the connector and part number directly.

Questions about this item

How do I choose between the 2-prong and 3-prong versions for my Shark Ion robot?

This battery only fits models with a 2-prong connector such as RV1001AE, RV700_N, RV720_N, RV725_N, RV750_N, RV761, RV850, RV850C, RV850WV, RV851WV, RV871, R75, R85 and RV1000S; it will not work with RV700, RV720, RV750, RV755 or any RVBAT700 battery.

What runtime can I expect from the 3600mAh capacity in my robot vacuum?

The 3600mAh lithium cell restores the original run time for compatible Shark Ion robots, letting the vacuum complete a full cleaning cycle on a single charge.

What does the 2-prong connector mean for installation and charging?

The 2-prong plug matches the robot's battery port exactly; remove two screws, swap the connector and the built-in protection circuits handle short-circuit, over-current, over-charge, over-voltage and overheat safety during charging.
