It slots into the IR-384P's battery compartment and powers the thermal detector, display, and onboard processing electronics. Capacity matches the original spec at 2200mAh (16.28Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIR-384P platform fit:\u003c\/strong\u003e\n    The IR-384P draws simultaneously from the thermal detector array, the LCD display backlight, and the image processing board. This battery's 7.4V nominal rail and cell configuration match the BMS handshake the camera expects — the camera will reject cells that fall outside its voltage recognition window on startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery under combined detector and display load. The BMS held the output rail steady through the thermal detector's constant heating draw and flagged low-battery correctly before the protection circuit cut off.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration tip:\u003c\/strong\u003e\n    After inserting a fresh battery, power on the IR-384P and let it sit idle for 60 seconds before taking any measurements. The thermal detector needs the internal electronics to stabilise before the baseline calibration is accurate — readings taken in the first 30 seconds on a cold start can be off by several degrees.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eThermal accuracy affected at low battery on the IR-384P\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe IR-384P's thermal detector array is voltage-sensitive. As cell voltage drops toward the lower end of the discharge curve — typically below 6.8V under load — the detector's heating element receives less stable power, and temperature readings can drift by a measurable margin before the battery indicator shows critical. This means the camera can appear to have usable charge remaining while thermal data accuracy is already compromised. Replace or recharge the battery when the indicator reaches one bar rather than waiting for a shutdown warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eIR-384P shutting down mid-inspection on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS interprets the combined peak draw of the display, detector array, and image processor as an overcurrent event and trips the protection circuit. It is most common in high-ambient-temperature environments where the camera housing is already warm, because heat raises the internal cell resistance and amplifies the apparent load spike. The fix is to power the camera off for 30 seconds to let the BMS reset, then restart. If shutdowns repeat in the same conditions, check that the battery contacts are clean — oxidised contacts increase resistance and push the load reading over the BMS threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426114043994,"sku":"BWCS-DLT300SL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426114076762,"sku":"BWCS-DLT300SL-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426114109530,"sku":"BWCS-DLT300SL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DLT300SL-1.webp?v=1779930364","url":"https:\/\/batteryweb.com\/products\/rno-ir-384p-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
