It replaces OEM part 88520 across the Eternal Genesis, Ultimate Genesis, Original, and Immortal Genesis variants, plus 16 additional Conga 7490 models. Capacity is drawn from verified product data at 2600mAh (37.44Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eConga 7490 series compatibility:\u003c\/strong\u003e\n    All listed Conga 7490 variants share the same 14.4V battery bay, connector pinout, and BMS handshake protocol. The same cell pack fits across this generation without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through full charge and discharge cycles on a Conga 7490 unit. The BMS handled cell balancing correctly, and the robot completed navigation cycles without mid-run voltage drop or unexpected shutdown.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habits on this robot:\u003c\/strong\u003e\n    Do not leave the Conga 7490 sitting on its dock indefinitely between uses. This robot's dock maintains a trickle charge once full, which accelerates capacity fade in Li-ion cells. Charge to full, then remove — only redock when the battery is depleted or you are starting a scheduled clean.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low on the Conga 7490\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Conga 7490 motor draws significantly more current when airflow is restricted — a blocked filter or partial blockage at the brush roll forces the motor to compensate. As current demand rises, cell voltage sags under load even though the battery reports adequate charge. The BMS reads this voltage sag as a low-battery condition and begins reducing power to the motor. Clean the HEPA filter and check the brush roll channel before assuming the battery is at fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRobot cuts out mid-clean then recovers after sitting for a minute\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a flat battery. When suction is sustained under restriction — typically a clogged filter or carpet fibres jamming the brush — current draw exceeds the BMS protection threshold and it cuts the circuit. The robot goes dark, then recovers once the BMS resets and cell voltage rebounds. Fix the restriction first. If the cutout continues on an unrestricted floor with a new battery, check that cell voltage under load stays above 12.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426384937050,"sku":"BWCS-UTC500VX-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426384969818,"sku":"BWCS-UTC500VX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426385002586,"sku":"BWCS-UTC500VX-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UTC500VX-1.webp?v=1779933315","url":"https:\/\/batteryweb.com\/products\/cecotec-conga-7490-eternal-genesis-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
