Shark Navigator SV116N Freestyle 10.8V Replacement Battery XBT1106N

Shark Navigator SV116N Freestyle — 10.8V Ni-MH Replacement Battery (XBT1106N)

This is a 10.8V, 3000mAh Ni-MH replacement battery for the Shark Navigator SV116N Freestyle and related cordless stick vacuums. It fits the SV116N, SV1106N, SV1110, and SV1110N among others using OEM part XBT1106N. Swap it in when the original cell no longer holds enough charge to finish a cleaning session.

• SV116N Freestyle platform fit: These models share a common 10.8V battery bay, connector pinout, and BMS handshake. The XBT1106N part number spans the whole Freestyle line because Shark held the voltage rail and physical format consistent across that generation.
• Bench tested on actual hardware: We cycled this cell on an SV116N and confirmed the BMS accepted the replacement without fault codes. The motor spun up to full speed and the overcurrent protection responded correctly at the draw levels a restricted filter produces.
• Dock charging habit on Freestyle vacuums: Do not leave the SV116N sitting on the charging dock permanently. Ni-MH cells in continuous trickle charge develop capacity fade significantly faster than cells charged only when depleted. Charge to full, then remove the vacuum from the dock.

Suction dropping before the battery indicator shows low

A degraded Ni-MH cell can no longer sustain voltage under the motor's draw, even when resting voltage appears acceptable. The vacuum's motor runs slower, and suction drops noticeably — but the indicator still reads mid-charge because it measures resting voltage, not load voltage. This is voltage sag under load, not a full discharge. A fresh cell rated at the correct 10.8V and 3000mAh restores the voltage headroom the motor needs to hold full suction through a cleaning session.

Motor cutting out and then recovering mid-clean

If the motor stops for a few seconds then restarts on its own, the BMS has tripped its overcurrent protection and reset. This usually happens when suction is restricted — a clogged filter forces the motor to draw harder to maintain airflow, and the current spike triggers the cutoff. Check and clean the foam and felt filters before replacing the battery. If the cutout persists with clean filters and the battery is the original cell, measure resting voltage: anything below 10.0V on a nominally full pack confirms cell degradation.
