It powers the motor, brush system, and onboard navigation electronics. Fits the RCV 2 platform directly — confirm your unit runs on 14.4V before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRCV 2 platform fit:\u003c\/strong\u003e\n    The RCV 2 operates on a 14.4V lithium-ion architecture that drives both the suction motor and the navigation sensors from a single cell pack. This replacement matches that voltage rail and the physical dimensions of the original pack — 70.50 x 37.20 x 37.00mm.\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 on the RCV 2 platform. The BMS handled motor start-up current without tripping and maintained voltage under sustained suction load across varying floor surfaces.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the RCV 2:\u003c\/strong\u003e\n    Remove the RCV 2 from its charging dock once the battery reaches full charge. Units left on the dock indefinitely pass a low trickle current through the cells continuously, which accelerates capacity loss in Li-ion packs. Charge when depleted, then undock.\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\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the RCV 2's motor draws more current than rated — usually because the filter is partially blocked or the brush roll is restricted. The battery voltage sags under that elevated load, and the motor loses power before the charge indicator registers a problem. The battery itself is not necessarily faulty. Clean the filter and clear the brush roll, then retest — if suction holds, the cell was never the issue.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRCV 2 motor cutting out mid-clean and then recovering\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, tangled brush, or debris in the inlet — the motor draws a sustained spike above the BMS threshold and the pack shuts output temporarily. The unit pauses, the BMS resets, and it starts again. Clear the restriction first. If the cutout continues on a clean filter with a new battery, measure pack voltage under load — it should hold above 12.5V during normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426402631770,"sku":"BWCS-EFL500VX-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426402664538,"sku":"BWCS-EFL500VX-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426402697306,"sku":"BWCS-EFL500VX-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EFL500VX-1.webp?v=1779933418","url":"https:\/\/batteryweb.com\/products\/karcher-rcv-2-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
