Shark XFBT200 Replacement Battery 10.8V 2000mAh Li-ion

Shark WV200UK — 10.8V Li-ion Replacement Battery (XFBT200)

This is a 10.8V, 2000mAh Li-ion replacement battery for the Shark WV200UK handheld cordless vacuum. It also fits the WV200, WV201, and WV205 models. Same voltage, same connector, same BMS handshake as the original XFBT200.

• WV200 series compatibility: The WV200, WV201, and WV205 share the same 10.8V battery platform and connector housing. The BMS in each model expects the same cell voltage range and charge termination signal — a mismatched cell pack will either refuse to charge or cut out under motor load.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on the WV200 platform. The BMS held cutoff correctly at low-cell threshold, and charge termination triggered cleanly without the charger locking out — common with aftermarket cells that spoof the handshake incorrectly.
• Dock charging on the WV200 series: Do not leave the vacuum sitting on the charging dock permanently. Continuous trickle charging accelerates capacity fade on Li-ion cells in handheld vacuums faster than regular charge-and-remove cycles. Charge to full, then pull it off the dock.

Suction dropping before the battery indicator shows low

The WV200's suction motor draws significantly more current when the filter is partially blocked. A restricted airflow path forces the motor to work harder, pulling the cell voltage down faster than the indicator circuit registers. The battery indicator reads state-of-charge from resting voltage, not under-load voltage — so it can show two bars while the motor is already starving. Clean or replace the filter first, then retest suction under load.

Motor cuts out mid-use then recovers after a short pause

This is a BMS overcurrent trip, not a dying battery. When the vacuum picks up a blockage or runs against dense carpet fibres, the motor draws a current spike that the BMS reads as a fault condition and shuts the pack down. After 10–30 seconds, the BMS resets and power returns. Clear any blockage from the nozzle and filter path, then test again — if the cutout stops, the cell is fine. If it persists on a clear filter, check that the replacement pack's BMS overcurrent threshold matches the OEM spec at 10.8V nominal.
