It fits the Conga 5090, 5490, 6090, and 7090 models. Capacity figures are taken directly from the product specification — 76.96Wh total.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eConga 5090–7090 compatibility:\u003c\/strong\u003e\n    These four models share the same 14.8V battery rail, connector pinout, and BMS communication protocol. The MH1-4S2P-300S cell pack slots into each chassis without modification and the robot's charge management system reads the replacement cell correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on a Conga unit. The BMS reported cell balance correctly, the robot completed navigation passes without mid-cycle cutoff, and charge termination triggered at the expected voltage ceiling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on Conga robots:\u003c\/strong\u003e\n    Do not leave the Conga sitting on its dock between uses permanently. These robots return to dock automatically, so the charger stays active continuously — this trickle charges the Li-ion pack and accelerates capacity fade. Charge to full, then remove the dock power 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 on Conga 5090\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA partially blocked filter forces the Conga's motor to draw significantly more current than rated. The BMS reads this spike as a high-load event and throttles output voltage to protect the cells — the robot loses suction while the indicator still shows charge remaining. This is not a battery fault. Clean or replace the HEPA filter first, then retest. If suction holds steady after filter service, the pack is functioning correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eConga motor cuts out mid-clean and then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a motor failure. When the vacuum hits a carpet edge or a blockage, suction restriction spikes the motor's current draw. The BMS trips the output circuit to prevent cell damage, then resets once current drops back within range. Check the brush roll for hair wrap and clear the filter before the next run. If trips continue on a clean unit, verify the pack resting voltage sits above 14.0V before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426412396634,"sku":"BWCS-CNS549VX-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426412429402,"sku":"BWCS-CNS549VX-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426412462170,"sku":"BWCS-CNS549VX-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNS549VX-1.webp?v=1779933160","url":"https:\/\/batteryweb.com\/products\/cecotec-conga-5090-replacement-battery-148v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
