Shark Pet Perfect SV70Z Replacement Battery 14.4V 2200mAh

Euro Pro Shark Pet Perfect Bagless — 14.4V Ni-MH Replacement Battery (XB14726)

This is a 14.4V, 2200mAh Ni-MH replacement battery for the Euro Pro Shark Pet Perfect Bagless vacuum cleaner. It fits the SV70Z and related SV70 series models, including the Shark Sweeper SV70 and EV729. When the original cell loses capacity or stops holding a charge, this unit restores the vacuum to working order.

• SV70 series fitment: The SV70Z, SV70, and EV729 share the same 14.4V battery platform, connector pinout, and BMS handshake. One cell covers the full range of these models without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the SV70Z platform. The BMS accepted the handshake from the charger correctly, and the motor drew current within the expected range under suction load without triggering overcurrent cutoff.
• Dock charging habit on the SV70 series: Do not leave the vacuum sitting on the charging dock between every use. The SV70 charger continues to trickle charge once the cell is full. Remove the vacuum from the dock when the charge cycle completes to slow capacity fade.

Suction dropping before the battery indicator reaches low on the SV70Z

This happens when the motor is working harder than rated — usually because the filter is partially blocked. A restricted filter forces the motor to draw more current, which causes voltage to sag at the cell before the indicator circuit registers a low state. The result is weak suction even with a battery that reads as charged. Clean or replace the foam and felt filters first, then retest suction under the same carpet load.

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

This is a BMS overcurrent trip, not a dead battery. When the motor sustains a high current draw — usually from a blockage in the nozzle or a clogged filter — the BMS shuts the output to protect the cell. The pack resets after the thermal or current condition clears, which is why the vacuum works again after a brief rest. Clear any blockage in the suction path, check the filter, and confirm the cell voltage reads at or above 14.4V after a full charge before ruling out the battery itself.
