It replaces the original cell pack when capacity has degraded to the point the unit can no longer complete a full cleaning cycle. Voltage and connector match the original so the onboard BMS accepts the swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePUCRC660, PUCRC675, PUCRC850 compatibility:\u003c\/strong\u003e\n    These three models share the same 14.4V battery bay, connector pinout, and BMS communication protocol. One cell pack covers all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on a PUCRC-series unit. The BMS accepted the cell, balanced across all nodes, and the vacuum completed full floor passes without a mid-cycle cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on robotic vacuums:\u003c\/strong\u003e\n    Do not leave the PUCRC660 sitting on the dock between uses indefinitely. Continuous trickle charging accelerates capacity fade in lithium cells faster than normal cycle wear. Charge to full, then remove from the dock until the next run.\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 PUCRC660's motor draws harder when airflow is restricted — a partially clogged filter or blocked intake forces the motor to pull more current than rated. The BMS reads that surge as an abnormal load and throttles power to the motor before the battery gauge reflects the actual cell state. The result is noticeably weaker suction while the indicator still shows mid-charge. Clear the filter and check the dustbin seal before assuming the battery is at fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-run then restarts on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the vacuum hits a carpet edge or sustained resistance, motor current spikes briefly above the BMS threshold and the pack shuts output to protect the cells. The BMS resets automatically once current drops, which is why the unit restarts seconds later. Check the brush roll for tangled hair or debris and clean the filter — both cause the sustained high-draw condition that triggers the trip repeatedly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428006985818,"sku":"BWCS-TVR500VX-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428007018586,"sku":"BWCS-TVR500VX-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428007051354,"sku":"BWCS-TVR500VX-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TVR500VX-1.webp?v=1779933850","url":"https:\/\/batteryweb.com\/products\/pure-clean-pucrc660-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
