It carries OEM part numbers JW-Y4S3P-6.6 and RRC2024. Capacity is rated at 112.32Wh, matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVG60 and VG70 platform fit:\u003c\/strong\u003e\n    Both ventilator models share the same 14.4V battery bay, connector pinout, and BMS communication protocol. One cell format serves both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on the VG60 platform and confirmed the BMS handshake completes correctly. The protection circuit responded to load within spec — no false low-voltage cutoffs during steady draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test procedure:\u003c\/strong\u003e\n    After fitting this battery, let the VG60 or VG70 complete its full startup self-test without interruption. The device runs a BMS verification sequence at boot. Interrupting it mid-cycle can register a false battery fault that stays latched until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVG60 low-battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe VG60's charge IC applies a conservative current limit on cells it hasn't profiled before. On the first charge cycle, the battery may reach the charge termination voltage before the BMS records a full-capacity baseline. The ventilator then reads state-of-charge against an incomplete reference and trips the low-battery alarm even though the cell is physically full. Run one complete charge-to-discharge cycle under normal ventilator operation and let the BMS update its capacity register. The alarm threshold should clear by the second full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVG60 failing to power on after battery storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the pack voltage drops below approximately 10V — roughly 2.5V per cell — the VG60's BMS will not initiate a charge cycle to prevent damage to over-discharged cells. The device appears completely dead: no display, no alarm, no response to the power button. Connect the ventilator to mains power and leave it on charge for at least two hours before attempting to power on. Most BMS circuits include a trickle pre-charge mode that recovers cells sitting between 2.0V and 2.5V per cell; confirm the charge LED activates within the first five minutes of connection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381463646298,"sku":"BWCS-PHD202MD-1","price":324.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381463679066,"sku":"BWCS-PHD202MD-2","price":384.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381463711834,"sku":"BWCS-PHD202MD-3","price":429.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHD202MD-1.webp?v=1778901015","url":"https:\/\/batteryweb.com\/products\/aeonmed-respirator-vg60-replacement-battery-144v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
