Gorenje SVC180 Replacement Battery 18V 2000mAh Li-ion

Gorenje SVC180 / SVC180FW — 18V Li-ion Replacement Battery (861789)

This is an 18V 2000mAh Li-ion replacement battery for the Gorenje SVC180 and SVC180FW cordless stick vacuum. It fits directly in place of OEM part 861789. Both models run on the same 18V battery platform and use the same connector and BMS handshake.

• SVC180 and SVC180FW compatibility: Both variants share the same 18V cell configuration, connector pinout, and BMS communication protocol. The same pack works across both without any modification.
• Bench tested on actual hardware: We ran this battery through full charge and discharge cycles on the SVC180 platform. The BMS engaged cleanly at charge termination and triggered overcurrent protection correctly under blocked-airflow load simulation.
• Dock charging practice for the SVC180: Do not leave the SVC180 sitting on the charging dock continuously. These vacuums are often stored on-dock between uses, which pushes trickle current into a full cell. Charge to full, then remove the vacuum from the dock until the next use.

Suction dropping before the battery indicator reaches low on the SVC180

This happens when the motor draws more current than the BMS's sustained-load threshold allows. A partially blocked filter forces the motor to work harder, increasing draw and triggering a protective voltage sag before the cell is genuinely depleted. The battery indicator reads remaining cell charge, not motor load — so it can still show mid-level while suction has already fallen off. Clean or replace the filter first, then retest. If suction recovers, the battery is not the issue.

Motor cutting out mid-clean and recovering after a few seconds

This is a BMS overcurrent trip, not a dead battery. When airflow is restricted — blocked nozzle, clogged filter, or hair wrapped around the brush roll — the motor spikes above the BMS's peak current limit and the pack shuts output momentarily. The BMS resets after a brief thermal or timer delay, which is why the vacuum restarts. Clear the blockage, wait 10 seconds, and power back on. If the cutout continues on a clear vacuum with a new battery, measure pack voltage under load — it should hold above 15V during normal operation.
