Gorenje SVC144FW 14.4V Replacement Battery 577276

Gorenje SVC144FW / SVC144FBK Series — 14.4V Li-ion Replacement Battery (577276)

This is a 14.4V, 3000mAh (43.2Wh) Li-ion battery pack for the Gorenje SVC144FW, SVC144FBK, VC2930, and VC2932-GS cordless stick vacuums. It replaces OEM part numbers 577276, 574791, and 728267. The pack slots into the same bay as the original and connects to the same BMS handshake the charger expects.

• SVC144FW, SVC144FBK, VC2930, VC2932-GS fit group: These four models share the same 14.4V motor rail, battery bay dimensions, and connector pinout. The BMS on each communicates the same charge-control signal, so one pack covers all four without modification.
• Bench tested on actual hardware: We cycled this pack through full discharge and recharge on the SVC144 platform. The BMS held cutoff at 10.8V under load and accepted charge current from the OEM dock without fault codes or interrupted charge cycles.
• Dock charging habit for this vacuum: The SVC144 series dock delivers a trickle charge once the pack reaches full. Leaving it on the dock continuously compresses cycle capacity faster than standard use. Charge to full, then remove from the dock until the next use.

Suction dropping before the battery indicator reaches low

The SVC144 motor draws more current when airflow is restricted — a partially blocked filter forces the motor to work harder, pulling the cell voltage down faster than the indicator tracks. The indicator reads state-of-charge, not real-time voltage sag, so the light stays green while suction is already weak. Wash or replace the filter first before assuming the battery is at fault. If suction recovers after a filter clean, the cell itself is likely fine.

Motor cuts out mid-clean then restarts after a few seconds

This is a BMS overcurrent trip, not a flat battery. It happens when sustained suction restriction — usually a near-blocked filter or a partial blockage in the nozzle — pushes current draw above the pack's trip threshold. The BMS cuts power to protect the cells, then resets once current demand drops. Clear the blockage and check the filter; if the cutout stops, the pack is working correctly. If it continues with a clean filter on flat floor, check that the replacement pack's BMS trip rating matches the OEM spec at 14.4V.
