It slots into the same bay, matches the OEM connector, and communicates with the robot's BMS using the same handshake as the factory cell. Capacity is sourced from the product specification — 3350mAh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eConga 11090 platform compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V cell architecture, connector pinout, and BMS communication protocol. The N160-4S1P cell configuration runs a 4S1P lithium arrangement, which means all four models draw from the same voltage rail and accept the same replacement pack 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 the Conga 11090 platform. The BMS engaged current limiting correctly during motor start and released cleanly after the load settled. No false low-battery cutoffs were triggered during sustained floor navigation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline for the Conga 11090:\u003c\/strong\u003e\n    Do not leave the robot parked on the charging dock indefinitely between cleaning sessions. The Conga 11090's dock delivers a trickle charge when the battery is full, which accelerates capacity fade in Li-ion cells. Charge to full, then remove the unit from the dock until the next 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\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the Conga 11090, motor voltage sag can occur well before the battery indicator signals a low state. When the filter is partially blocked or the brush roll is restricted, the motor draws above its rated current. The BMS interprets this sustained over-draw and begins throttling output voltage to protect the cells, which the robot translates as reduced suction power rather than a fault. Clean the filter and check the brush roll for hair wrap before assuming the battery is at fault — a clean airway drops motor current back into the normal operating band.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the Conga 11090 transitions from hard floor to thick carpet, or encounters a blockage, the motor load spikes sharply. If that spike exceeds the BMS overcurrent threshold — typically for more than a few seconds — the BMS disconnects the output to protect the cells, and the robot stops. It recovers once the BMS resets, usually within 10–30 seconds. Clear any obstruction from the intake, verify the filter is clean, and confirm the battery terminals are seated firmly before assuming a faulty cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426405122138,"sku":"BWCS-CNR119VX-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426405154906,"sku":"BWCS-CNR119VX-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426405187674,"sku":"BWCS-CNR119VX-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNR119VX-1.webp?v=1779933099","url":"https:\/\/batteryweb.com\/products\/cecotec-conga-11090-replacement-battery-144v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
