Over 35% of aftermarket Shark vacuum battery returns happen because the buyer ordered the wrong connector. Shark quietly revised models like the RV700, RV720, RV750, and RV850 mid-generation, meaning two robots with the exact same model number might have entirely different wiring plugs.
How to Check Your Plug (30-Second Inspection) Unscrew the 2 screws on your Shark's bottom battery door, pull the battery out, and count the metal pin slots inside the white plastic clip:
• 2 Wires (Red/Black) & 2 Slots: You have the 2-Pin RVBAT700.
• 3 Wires (Red/White/Black) & 3 Slots: You have the 3-Pin RVBAT700.
• 2 Wires (Red/Black) & 2 Slots: You have the 2-Pin RVBAT700.
• 3 Wires (Red/White/Black) & 3 Slots: You have the 3-Pin RVBAT700.
