It fits the VC-RCX1, VC-RVD1, VC-RVD2, and VC-RV1 among others. When the original cell degrades and suction drops off early in a clean, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVC-RCX1 and VC-RVD series compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V rail, physical connector, and BMS communication protocol, which is why a single cell pack covers the full group. Swapping voltage or connector type between these variants causes immediate BMS rejection at power-on.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on the VC-RCX1 platform under simulated carpet and upholstery loads. The BMS held voltage correctly through full discharge cycles without false low-battery cutoffs, and the charge handshake with the original dock completed without error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline for this vacuum:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock continuously between uses. The VC-RCX1 dock does not drop to a true maintenance mode — prolonged dock contact pushes a trickle charge into the cells that accelerates capacity fade. Charge to full, then remove it.\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 motor in the VC-RCX1 draws more current when airflow is restricted — a partially blocked filter can push draw well above the rated operating current. The BMS reads this spike as an unsafe load and begins throttling output voltage before the fuel gauge has time to register a problem. The result is weak suction with a battery indicator that still shows half charge or more. Clean or replace the filter first, then retest — if suction restores immediately, the battery was not the fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-use and then recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the motor encounters sustained resistance — thick carpet, a partial blockage, or a clogged filter — current draw spikes past the BMS threshold and the pack shuts output to protect the cells. After 10–30 seconds the BMS resets and power returns. The fix is to clear the restriction before the next run. If the cutouts continue on a fully clear airpath, measure resting pack voltage after a full charge — it should read 16.4V or above.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428028481626,"sku":"BWCS-TRX100VX-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428028514394,"sku":"BWCS-TRX100VX-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428028547162,"sku":"BWCS-TRX100VX-3","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TRX100VX-1.webp?v=1779933918","url":"https:\/\/batteryweb.com\/products\/toshiba-vc-rcx1-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
