It fits directly into the handheld unit and restores power to the motor for floor, carpet, and upholstery cleaning. Capacity is 1800mAh (17.28Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePUCRCX70 Version 2 fit:\u003c\/strong\u003e\n    This battery matches the 9.6V rail and connector layout specific to the Version 2 handset. The BMS communicates charge state to the vacuum's indicator circuit, so the battery level display behaves the same as the factory cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the PUCRCX70 Version 2 platform. The BMS held cutoff voltage cleanly at the low end and accepted a full charge without triggering the charger's fault indicator.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging practice for LiFePO4 cells:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. LiFePO4 cells in cordless vacuums develop capacity fade faster under continuous trickle charge than those removed from the dock once fully charged. Charge to full, then disconnect.\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\"\u003eThis happens when a partially blocked filter forces the motor to draw more current than rated. The BMS reads the elevated draw as a discharge stress event and reduces output voltage to protect the cell — suction drops, but the indicator still shows charge remaining. Clean or replace the filter first. If suction recovers immediately after, the battery is not the cause. If suction stays weak with a clean filter, measure terminal voltage under load — it should hold above 9.0V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-run 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 suction airflow is restricted — blocked filter, stuck debris in the path — the motor works harder and pulls a current spike the BMS treats as a fault. It cuts power, the motor cools briefly, and the BMS resets, allowing the vacuum to restart. Clearing the blockage stops the cycle. If the cutout continues on a clean, unobstructed vacuum, check that the replacement cell's BMS trip threshold matches the motor's start surge by confirming charger compatibility first.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427985129562,"sku":"BWCS-PCX700VX-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427985162330,"sku":"BWCS-PCX700VX-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427985195098,"sku":"BWCS-PCX700VX-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PCX700VX-1.webp?v=1779933649","url":"https:\/\/batteryweb.com\/products\/pure-clean-pucrcx70-version-2-replacement-battery-96v-1800mah-lifepo4","provider":"BatteryWeb","version":"1.0","type":"link"}
