It uses an INR18650M26 3S1P cell configuration — three 18650 cells in series — matching the voltage rail the motor controller expects. Capacity is 2600mAh (28.08Wh), direct from our sourcing spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eConga 750 and Slim series fitment:\u003c\/strong\u003e\n    These models share the same 10.8V motor bus, connector pinout, and BMS handshake protocol. The 3S1P cell arrangement keeps the pack within the chassis footprint while delivering the current the suction motor draws during a cleaning cycle.\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 890 Slim unit. The BMS correctly flagged overcurrent on a blocked-filter test and cut power cleanly — no thermal event, no false low-charge signal at full state of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for these models:\u003c\/strong\u003e\n    Do not leave the Conga on the charging dock continuously. These robot vacuums apply a trickle charge when docked and full — sustained trickle current degrades cell capacity faster than normal cycling. Charge to full, then remove from the dock until the next run.\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 Conga Slim models\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the suction motor draws more current than the BMS allows under load — usually caused by a partially blocked filter or brush roll, not a flat battery. The motor voltage sags under restriction, the BMS reads it as an overload condition, and it throttles output. Clean the filter and check the brush roll for hair wrap before assuming the battery is at fault. If suction recovers after cleaning, the pack is fine — the cell was never the problem.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-cycle and restarts after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When sustained suction restriction forces the motor to draw above the pack's rated discharge current, the BMS opens the circuit to protect the cells. It resets automatically once current demand drops. The fix is to clear the filter and check the inlet for blockages — a clean airpath keeps motor draw below the trip threshold. If cutouts continue on an unobstructed vacuum, verify the replacement pack's discharge rating matches the OEM spec of 10.8V \/ 2600mAh.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428018946138,"sku":"BWCS-CNS890VX-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428018978906,"sku":"BWCS-CNS890VX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428019011674,"sku":"BWCS-CNS890VX-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNS890VX-1.webp?v=1779933823","url":"https:\/\/batteryweb.com\/products\/cecotec-conga-750-replacement-battery-108v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
