It slots in as a direct swap for OEM part number BP-INCU II. The INCU II relies on this pack to sustain temperature-controlled incubation cycles when mains power is interrupted.\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 7.4V battery bay, connector pinout, and BMS handshake protocol — one pack covers both platforms without any hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the INCU II platform. The BMS communicated correctly with the instrument's charge controller, and the protection circuit responded as expected to over-voltage and over-current conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation cycle for the INCU II:\u003c\/strong\u003e\n    After fitting a new pack, run one complete incubation cycle at your standard set-point temperature before relying on backup power. The instrument maps battery state during an active thermal cycle, and skipping this step can trigger early low-battery warnings before any real capacity loss occurs.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the INCU II drops out during incubation with no apparent warning\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe INCU II heater element draws a short surge current each time the thermal controller fires to maintain set-point temperature. An aged or partially discharged cell can't sustain that surge — internal resistance rises, the terminal voltage dips below the BMS cutoff threshold, and the unit shuts down mid-cycle. This isn't a firmware fault or a heater fault; it's a cell-level voltage collapse under load. A fresh 10200mAh pack restores the current headroom the heater circuit expects. If shutdowns continue after fitting a new pack, check the charger output voltage — it should read between 8.2V and 8.4V at the charging port.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eINCU II won't power on after the battery sat unused for several months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge over time, and a pack left in storage or in a shelved instrument can drop below the BMS recovery threshold — typically around 2.5V per cell. When that happens, the protection circuit stays latched in shutdown and the instrument sees no battery at all. Connect the INCU II to mains power first and leave it on charge for at least four hours without pressing the power button. This allows the charger to push a low trickle current through the BMS latch and bring the cells back above the 3.0V-per-cell recovery floor. If the charge indicator still doesn't respond after four hours, measure the pack voltage at the connector — anything below 5.0V total indicates the cells need a forced recovery charge or the pack should be replaced.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360657408090,"sku":"BWCS-FBP653XL-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360657440858,"sku":"BWCS-FBP653XL-2","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360657473626,"sku":"BWCS-FBP653XL-3","price":82.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FBP653XL-1.webp?v=1778616161","url":"https:\/\/batteryweb.com\/products\/fluke-biomedical-incu-ii-incubator-replacement-battery-74v-10200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
