It slots into the battery bay and connects to the same BMS interface as the original cell. Voltage, capacity, and connector format match the product data above.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eR750-2200pa, G800, and G850 platform:\u003c\/strong\u003e\n    These three models share the same 14.4V battery bay, connector pinout, and BMS communication protocol — which is why a single cell covers all three. Swapping between a G800 and an R750-2200pa does not require any adapter or firmware change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles, confirmed the BMS handshake completed correctly, and checked that the protection circuit triggered at the expected undervoltage threshold without nuisance tripping during normal motor load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the R750-2200pa and G800:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. These models trickle-charge the cell continuously when docked, which accelerates capacity fade faster than charging only when the battery is depleted. Charge to full, then remove from the dock.\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\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Coredy R750-2200pa and G800 regulate suction motor speed based on available voltage from the cell. When the battery ages or a filter is partially blocked, the motor draws more current than rated, causing the cell voltage to sag under load. The vacuum reads this sag as reduced power available and drops suction — even though the indicator still shows charge remaining. Cleaning or replacing the filter is the first step; if suction recovers, the cell was not the root cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and then recovering after a pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a depleted battery. When sustained restricted airflow forces the motor to pull above the protection circuit's current threshold, the BMS disconnects the cell to prevent cell damage. The vacuum powers back on after a short rest because the BMS resets once current demand drops. Clear the dustbin and filter, then restart — if the cut-out stops occurring, the restriction was the cause, not the cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426438774874,"sku":"BWCS-CNS591VX-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426438807642,"sku":"BWCS-CNS591VX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426438840410,"sku":"BWCS-CNS591VX-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNS591VX-1.webp?v=1779933286","url":"https:\/\/batteryweb.com\/products\/coredy-r750-2200pa-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
