Shark Navigator SV116N Replacement Battery 10.8V 3000mAh

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

This is a 10.8V, 3000mAh Ni-MH replacement battery for the Euro Pro Shark Navigator SV116N Freestyle and SV1106N cordless vacuums. It slots into the same bay as the original XBT1106N pack and restores cordless operation. Capacity is drawn from the product specification — 3000mAh, 32.4Wh.

• SV116N and SV1106N platform: Both models run the same 10.8V cell arrangement with an identical connector and BMS handshake requirement. One replacement battery covers either unit without any modification.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the SV116N platform. The BMS accepted the charger handshake correctly, cell balancing completed without fault flags, and the motor controller received a stable voltage rail throughout discharge.
• Dock charging habit on Shark stick vacuums: Leaving the SV116N on the charging dock continuously accelerates Ni-MH capacity fade. Ni-MH cells are sensitive to trickle overcharge in a way Li-ion packs are not. Charge fully, then remove from the dock until the next use.

Suction dropping before the battery indicator reaches low on the SV116N

Ni-MH cells under increased motor load will sag in voltage before the fuel gauge registers a low-battery state. On the SV116N, a partially blocked filter forces the motor to draw harder to maintain airflow, which pulls more current and triggers early voltage sag. The result is a noticeable drop in suction while the indicator still shows charge remaining. Check and clean the foam and felt filters first — on a clear filter, the battery voltage holds closer to its rated rail under the same motor load.

Motor cutting out mid-clean and then recovering after a pause

This is a BMS overcurrent trip, not a dead battery. When the SV116N motor sustains high current draw — usually from restricted airflow caused by a blocked filter or a partial blockage in the nozzle — the BMS cuts the circuit to protect the cells. A short pause lets the BMS reset and the motor restarts. The fix is to clear the blockage and clean the filter so sustained draw stays within the BMS threshold. If the cutout continues after the filter is clean, measure resting pack voltage after a full charge — it should read at or above 12.9V on a healthy Ni-MH pack at this cell count.
