Electrolux EUP82MG 29.6V Cordless Vacuum Compatible Battery 2000mAh

Electrolux EUP82MG Series — 29.6V Li-ion Replacement Battery (140112530252)

This is a 29.6V 2000mAh (59.2Wh) lithium-ion battery for the Electrolux EUP82MG cordless stick vacuum and related models. It replaces OEM part numbers 140112530252, 140112530047, 140112530179, and 140112530278. The battery slots into the vacuum's power module and restores full motor and suction function.

• EUP82MG, EUP82RR, and 900278801 01 platform: These models share the same 29.6V battery rail, connector housing, and BMS handshake protocol. A replacement cell that matches those parameters will seat, communicate, and discharge correctly across the whole platform.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the EUP82MG platform. The BMS negotiated correctly, charge acceptance was normal, and the overcurrent protection tripped at the expected threshold under simulated motor load.
• Dock charging habit on cordless vacuums: Do not leave the vacuum on the charging dock permanently. Continuous trickle charging accelerates capacity fade on Li-ion cells at this voltage class. Charge fully, then remove from the dock until the next use.

Suction dropping before the battery indicator reaches low

On the EUP82MG, the motor draws higher current whenever the filter is partially blocked — even blockage that isn't visible. That extra draw pulls the cell voltage down under load before the battery gauge registers a problem. The vacuum loses suction noticeably while the indicator still shows a mid or high charge. Cleaning or replacing the filter restores normal current draw and brings performance back in line with the battery's actual state of charge.

Motor cutting out mid-clean and then recovering after a short pause

This is a BMS overcurrent trip, not a faulty battery. When the filter restricts airflow, the motor labours and pulls sustained current above the BMS threshold — the protection circuit cuts power to prevent cell damage. After a short pause, the BMS resets and the vacuum starts again. The fix is the filter, not the battery: clear any blockage and check the filter is seated correctly, then confirm the cell rests above 25V before restarting.
