It supports continuous vital sign monitoring during patient transport and assessments when AC power is unavailable. Capacity is 38.48Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNV8 monitor fit:\u003c\/strong\u003e\n    The NV8 draws from a 14.8V four-cell Li-ion pack with a specific BMS handshake. This cell configuration matches that voltage rail and connector, so the monitor's power management system communicates correctly with the pack from first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the NV8 power-on sequence and monitored BMS communication. The pack passed the device's startup self-test and held voltage steady across the full monitoring load profile without triggering a false low-battery event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After fitting this battery, let the NV8 complete its full power-on self-test without interruption. The device runs BMS verification at startup — cutting power during this sequence creates a false battery fault that sticks 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\"\u003eNV8 not completing boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe NV8 runs a BMS learn cycle on first use — if the cell voltage is below the device's minimum boot threshold after storage, the monitor may stall partway through startup. A new cell that has self-discharged during shipping can sit just under that threshold. Connect the monitor to AC power first, allow a full charge, then boot without AC. This resets the BMS state and the boot sequence completes normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe NV8's charge IC applies a conservative current limit when it detects a new or cold cell, which means the first charge cycle often terminates early at 90–95% indicated. This is the charge controller protecting the cell, not a fault. Run one full charge-discharge cycle — charge to termination on AC, use the monitor on battery until the low-battery alarm triggers, then recharge fully. After that cycle the charge IC recalibrates and the indicator reaches 100%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381407547482,"sku":"BWCS-CNV800MD-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381407580250,"sku":"BWCS-CNV800MD-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381407613018,"sku":"BWCS-CNV800MD-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNV800MD-1.webp?v=1778900597","url":"https:\/\/batteryweb.com\/products\/comen-nv8-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
