Bissell ICONpet 2291 Replacement Battery 18.5V 5000mAh

Bissell ICONpet 2291 Series — 18.5V Li-ion Replacement Battery (69-0083-006)

This 18.5V Li-ion battery replaces part number 69-0083-006 in the Bissell ICONpet 2291, 2291A, 2291+, and P488 cordless stick vacuums. Capacity is 5000mAh (92.5Wh), matching the original cell specification. It fits the same connector and communicates with the same BMS as the factory pack.

• ICONpet 2291 series compatibility: The 2291, 2291A, 2291+, and P488 all run the same 18.5V power rail and share an identical battery connector and BMS handshake protocol. One cell fits all variants without adaptation.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on a 2291A unit. The BMS balanced cells correctly, thermal sensors responded normally, and the charger completed a full charge cycle without fault codes.
• Dock charging practice for the ICONpet: Do not leave the vacuum sitting on the charging dock continuously. The ICONpet dock delivers a low-level trickle current when the pack is full, and sustained trickle charging accelerates capacity fade in Li-ion cells. Charge to full, then remove the vacuum from the dock.

Cordless vacuum losing suction before the battery indicator reaches low

This happens when the motor draws more current than the BMS expects under a restricted airflow condition. A partially blocked filter forces the motor to work harder, spiking current draw and causing voltage to sag at the pack before the indicator registers a low state. The vacuum loses suction because available voltage drops below the motor's operating threshold, not because the cell is depleted. Clean or replace the filter and confirm pack voltage reads at least 18V under load before assuming the battery is at fault.

Motor cuts out mid-use and recovers after a few seconds

This is a BMS overcurrent trip, not a failed battery. When sustained suction blockage — mat fibres, dense pet hair, or a clogged post-motor filter — forces continuous high current draw, the BMS cuts output to protect the cells. The pack resets automatically once temperature and current normalise, typically within a few seconds. Clear the blockage, check both the pre-motor and post-motor filters, then restart. If the trip repeats on a clear airpath, check resting pack voltage; anything below 17.5V indicates a cell that needs replacement.
