Goddess CL490 Cordless Vacuum Replacement Battery 14.4V 2000mAh

Goddess CL490 — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 2000mAh Ni-MH replacement battery for the Goddess CL490 cordless vacuum cleaner. It slots into the CL490's battery compartment and powers the handheld motor for floor and surface cleaning. Replace this when the original cell no longer holds enough charge to complete a cleaning session.

• CL490 fit: The CL490 runs a 14.4V Ni-MH chemistry at this exact cell configuration. Swapping to Li-ion or a different voltage would trip the vacuum's motor controller — this replacement keeps the same chemistry so the existing charging circuit works without modification.
• Bench tested on actual hardware: We cycled this cell under a sustained motor load matching the CL490's draw. The BMS held voltage steady through normal carpet and hard-floor passes and cut off cleanly at the low-cell threshold without requiring a manual reset.
• Dock charging on the CL490: Do not leave the CL490 sitting on the charging dock permanently. Ni-MH cells on continuous trickle charge develop capacity fade faster than cells charged only when depleted. Charge to full, then remove the vacuum from the dock.

Cordless vacuum losing suction before the battery indicator reaches low

The CL490 motor draws more current when airflow is restricted — a partially blocked filter or clogged brush head forces the motor to work harder than rated. Under that extra load, cell voltage sags early and suction drops noticeably before the battery indicator triggers. The battery itself is not necessarily failing; the motor is pulling more than it should. Clear the filter and check the brush roll before concluding the cell is at fault.

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

This is a BMS overcurrent trip, not a dead battery. When suction is sustained against a blockage — a clogged filter, a jammed brush roll, or heavy debris — current draw spikes and the BMS shuts the motor off to protect the cells. Letting the vacuum sit for 30–60 seconds resets the trip. Fix the restriction first: clean or replace the filter, clear the brush roll, and confirm the cell rests above 12V on an open-circuit check before recharging.
