It slots into the same position as the original pack and runs through the same BMS handshake the charger expects. Use the capacity figure above — 2600mAh — as the reference spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePVCR-0726W \/ PVCR-0926W platform fit:\u003c\/strong\u003e\n    These models share a 14.4V battery architecture with a common connector and BMS communication protocol. A replacement cell that does not match the voltage rail and handshake will either refuse to charge or trigger an immediate fault on the dock.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the PVCR platform. The BMS held cutoff correctly at low-cell voltage and accepted charge without triggering dock fault indicators.\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 permanently. Cordless vacuums on continuous dock charge accumulate trickle-charge stress faster than most users expect. Charge to full, then remove from the dock until the next use.\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\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the BMS threshold allows under load — typically caused by a partially blocked filter, not a failing battery. The BMS reads the increased current draw as a stress event and starts throttling output voltage before the fuel gauge registers low. Clean or replace the filter first. If suction recovers fully after that, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean 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 sustains restricted airflow, current spikes past the BMS protection threshold and the pack disconnects to prevent cell damage. The pause lets the BMS reset and re-engage. Check the filter and brush roll for blockage before replacing the battery. If the cutout stops after clearing the restriction, the original pack may still have usable capacity left.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428027990106,"sku":"BWCS-EDN620VX-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428028022874,"sku":"BWCS-EDN620VX-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428028055642,"sku":"BWCS-EDN620VX-3","price":50.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EDN620VX-1.webp?v=1779933901","url":"https:\/\/batteryweb.com\/products\/polaris-pvcr-0726w-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
