It runs the suction motor and navigation system from the same voltage rail as the factory unit. OEM part numbers CONG1002, 49CE1401, 1090-00000, and 35019072 all cross-reference to this cell configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eConga 990 \/ 950 \/ 1090 \/ 1190 compatibility:\u003c\/strong\u003e\n    These models share a common 14.4V bus, the same physical connector, and a BMS handshake protocol that this cell supports. Swapping voltage or skipping BMS compatibility will cause the charger to reject the pack or the robot to shut down mid-cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the Conga 990 charge and discharge cycle on the bench. The BMS accepted the charger handshake on first connect, held voltage under simulated motor load, and triggered overcurrent protection correctly when the motor draw spiked above threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for Conga robots:\u003c\/strong\u003e\n    Conga models left permanently on the charging dock trickle-charge continuously once full. This degrades cell capacity faster than any other single factor. Charge to full, then remove the robot from the dock until the next cleaning session.\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 990\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Conga 990's suction motor draws current in proportion to airflow restriction. When the filter is partially blocked, the motor pulls harder to maintain suction — this increases current draw and causes the cell voltage to sag under load well before the charge indicator registers low. A degraded battery accelerates this sag because its internal resistance is higher, so the voltage drop under the same load is steeper. The robot's protection circuit reads this voltage dip as low battery and reduces motor power as a safety measure. Clean or replace the filter first, then retest — if sag persists on a new filter, the cell itself needs replacing.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a charging fault. When the Conga's intake is partially blocked — often by hair wrapped around the brush roll or a clogged filter — the motor sustains a high-draw state that pushes current above the BMS threshold. The BMS cuts the circuit to protect the cell, then resets once current drops and temperature normalises. The fix is mechanical: clear the blockage, remove debris from the brush roll, and check the filter. If the motor cuts out again on a clean unit, measure resting cell voltage — anything below 12.8V at rest on a fully charged pack points to a weak cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428022190170,"sku":"BWCS-CNS990VX-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428022222938,"sku":"BWCS-CNS990VX-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428022255706,"sku":"BWCS-CNS990VX-3","price":50.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNS990VX-1.webp?v=1779933899","url":"https:\/\/batteryweb.com\/products\/cecotec-conga-990-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
