It replaces OEM part BP-INCU II directly. The INCU II runs continuous thermal regulation cycles, so the battery must hold voltage consistently under sustained sensor and heater-control load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eINCU II and Radiant Warmer Analyzer compatibility:\u003c\/strong\u003e\n    Both instruments share the same BP-INCU II battery format, voltage rail, and connector. The BMS handshake is identical across both platforms, so one cell pack serves either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the INCU II's thermal regulation load profile. The BMS held the 7.4V rail stable under the continuous heater-control and sensor draw without triggering a protection cutoff at any point during discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation calibration on the INCU II:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the instrument menu before using it in the field. The INCU II maps battery state during calibration. Skipping this step causes premature low-battery warnings during the first incubation session, even when the pack is fully charged.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the INCU II sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the INCU II sat unused long enough, the pack voltage can drop below the BMS recovery threshold — typically around 2.5V per cell. At that point, the BMS enters sleep mode and the instrument shows no charge activity even when connected to the charger. To recover the pack, connect it to the OEM charger and leave it for at least 30 minutes before checking for a charge indicator. If the charger still shows no activity, the cells have dropped below the recovery floor and the pack needs replacement.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eINCU II display showing an inconsistent battery percentage immediately after reboot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe INCU II estimates charge level by reading cell voltage at startup. A new pack has a different voltage-to-capacity curve than the degraded original, so the instrument's internal threshold map is temporarily out of sync. This causes the percentage indicator to jump or read low even on a full charge. Running the calibration cycle through the instrument menu forces the INCU II to re-map its thresholds to the new cell, which resolves the inconsistent readout. After one full calibration, the display should track accurately across the discharge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360656818266,"sku":"BWCS-FBP653SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360656851034,"sku":"BWCS-FBP653SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360656883802,"sku":"BWCS-FBP653SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FBP653SL-1.webp?v=1778616161","url":"https:\/\/batteryweb.com\/products\/fluke-biomedical-incu-ii-incubator-replacement-battery-74v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
