It replaces OEM part numbers NT-L14S1P-PA, NT-LI4S1P-PA, 022-000069-00, and 022.01.000069-00. The battery restores power to the Virgo unit when the original cell depletes or fails.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVirgo platform compatibility:\u003c\/strong\u003e\n    All four OEM part numbers listed map to the same 14.8V four-cell lithium-ion configuration used across Virgo variants. The connector, BMS handshake protocol, and voltage rail are identical across these part numbers — swapping between them does not require firmware changes or calibration steps.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the Virgo's full charge-discharge sequence and monitored BMS communication at each stage. The protection circuit responded correctly to charge termination and low-voltage cutoff without triggering false fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, allow the Virgo to complete its full power-on self-test cycle without interruption. Medical devices run BMS verification at startup, and cutting power mid-sequence can register a false battery fault that persists 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\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Virgo runs a BMS handshake during startup to verify cell chemistry and state of charge. A new replacement cell that has partially self-discharged during storage can report a state-of-charge value the device interprets as a fault, stalling the boot sequence before it completes. Charge the battery fully before the first boot — the charge IC applies a conservative limit on new cells, so the first charge cycle may stop short of 100% on the indicator. After one complete charge-discharge cycle, the BMS recalibrates and the boot sequence proceeds normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis alarm fires when the BMS self-test threshold is set against OEM cell chemistry parameters, and a new replacement cell hasn't yet passed a conditioning cycle. The Virgo's charge IC reads internal resistance during startup — a fresh cell out of storage shows higher impedance than a cycled one, which the device flags as low capacity even at full charge. Run one complete charge-discharge cycle before clinical use. After that cycle the impedance reading drops into the accepted range and the alarm clears at a normal charge level above 14.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381394210906,"sku":"BWCS-NRT690MD-1","price":125.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381394243674,"sku":"BWCS-NRT690MD-2","price":149.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381394276442,"sku":"BWCS-NRT690MD-3","price":167.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NRT690MD-1.webp?v=1778900564","url":"https:\/\/batteryweb.com\/products\/northern-virgo-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
