It replaces the original cell when capacity has faded and the robot no longer completes its cleaning cycle. Dimensions are 132.00 × 38.60 × 36.80mm — confirm against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eConga 9590, 9990, and 10090 share this cell:\u003c\/strong\u003e\n    All three models run the same 14.4V rail and use the same physical form factor and BMS communication protocol. A pack that seats and handshakes correctly in one will do the same in the others.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a Conga 9990 unit. The BMS handshook with the charger without fault codes, the voltage held stable through the motor-start surge, and the protection circuit tripped correctly at the low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the Conga platform:\u003c\/strong\u003e\n    Do not leave the robot sitting on the charging dock between cleaning sessions permanently. Continuous trickle charge on this cell chemistry accelerates capacity fade. Charge to full, run a cycle, and repeat — do not use the dock as a storage cradle.\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 shows low on the Conga 9990\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Conga's suction motor draws significantly more current when airflow is restricted — a partially blocked filter forces the motor to work harder, which pulls the cell voltage down faster than the indicator expects. The indicator is calibrated against a clean-filter current draw profile, so voltage sag under restriction reads as normal until the cell is nearly flat. The result is noticeably weaker suction well before the low-battery alert fires. Clean or replace the HEPA filter first — if suction recovers, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-run and then recovering after a few seconds\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a battery failure in most cases. When the brush roll or intake is partially blocked, the motor current spikes above the BMS protection threshold and the pack shuts the output to protect the cells. After a few seconds the BMS resets and the motor restarts. Clear any debris from the brush roll and intake, then check that the filter is not clogged. If cut-outs stop after cleaning, the pack is functioning correctly. If cut-outs continue on a clear machine, check that resting cell voltage is above 12.8V before assuming a faulty pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426401321050,"sku":"BWCS-CNS959VX-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426401353818,"sku":"BWCS-CNS959VX-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426401386586,"sku":"BWCS-CNS959VX-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNS959VX_1.webp?v=1779933099","url":"https:\/\/batteryweb.com\/products\/cecotec-9990-spin-revolution-ultra-power-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
