The Winbot W733 is a wall-climbing window cleaner — not a floor vacuum — and this cell matches the voltage rail and connector the unit's BMS expects. Capacity figures come from the product data, not inflated web claims.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eW733, W720, and TBW60 compatibility:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell Li-ion architecture and the same OEM battery slot dimensions (69.50 × 55.30 × 19.40mm). The BMS handshake protocol is identical across the range, so one cell covers all listed variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a W733 unit. The BMS accepted the replacement without error flags, held voltage within spec across the full suction and navigation load cycle, and the safety cutoff triggered correctly at low-cell threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eWindow cleaning cycle care:\u003c\/strong\u003e\n    The Winbot W733 runs a continuous load profile — motors, suction, and navigation draw simultaneously throughout each session. Avoid interrupting a mid-cycle run to recharge; partial discharge into a warm cell accelerates capacity fade faster than completing the cycle first.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the W733 loses suction and wall grip before the battery indicator drops low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe W733 runs suction and drive motors in parallel. When the cell voltage sags under combined load — especially on a worn or partially degraded battery — the suction motor drops output before the BMS triggers a low-voltage warning. The indicator reads remaining charge, not actual voltage under load, so the gap between \"apparent charge\" and real delivery widens as the cell ages. A replacement cell at full capacity closes that gap and restores consistent suction pressure across the full cleaning path.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReplacement battery not accepted by the charger after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe W733 charger communicates with the battery BMS before beginning a charge cycle. If the replacement cell has been stored in a deeply discharged state, the BMS may present a voltage too low for the charger to initiate. Connect the battery to the unit first and attempt a short power-on — this wakes the BMS. If the charger still won't start, measure the pack voltage at the contacts; anything below 9V requires a low-current pre-charge recovery before normal charging will begin.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427974545498,"sku":"BWCS-EDW710VX-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427974578266,"sku":"BWCS-EDW710VX-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427974611034,"sku":"BWCS-EDW710VX-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EDW710VX-1.webp?v=1779933520","url":"https:\/\/batteryweb.com\/products\/ecovacs-winbot-w733-replacement-battery-111v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
