It fits models listed under the Raytheon Thermal Imager line used for building inspections, electrical diagnostics, and field operations. Voltage and capacity match OEM spec exactly — no modifications needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRaytheon Thermal Imager compatibility:\u003c\/strong\u003e\n    These cameras share a 7.4V two-cell Li-ion configuration with a BMS that monitors both voltage rails and enforces a hard cutoff if either cell drifts. The HYLB-1061B form factor and connector match the original bay geometry, so the pack seats and latches correctly without forcing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge cycles on a Raytheon-class thermal camera load, monitoring BMS response under combined draw from the detector heating element and display backlight. Cell balance held within 30mV across both cells through repeated discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDetector warm-up after battery swap:\u003c\/strong\u003e\n    After inserting a fresh battery, allow the camera to run for at least 60 seconds before starting measurements. The uncooled thermal detector needs the internal electronics to reach a stable baseline temperature — readings taken too early will show elevated noise and drift in the infrared image.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eThermal accuracy degrading before the battery indicator shows low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eUncooled microbolometer detectors in thermal cameras are sensitive to supply voltage. As the pack approaches 6.8V — still above the BMS hard cutoff — the detector bias circuit starts receiving under-spec voltage, and temperature measurement accuracy begins to drift before any low-battery warning appears. This is not a fault with the battery; it is a characteristic of how the detector circuit is powered. If measurements start looking inconsistent or temperature deltas appear smaller than expected, check cell voltage directly. Swap the battery when resting voltage drops below 7.0V to keep measurements within spec.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera shutting down mid-inspection despite showing partial charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Raytheon thermal camera draws current from two parallel paths simultaneously — the detector heating element and the display backlight. Under peak combined draw, an aged or partially discharged cell can sag below the BMS protection threshold momentarily, triggering a hard shutdown even when the fuel gauge still reads 30–40%. This is a voltage sag event, not a capacity fault. A replacement pack with fresh cells eliminates the sag because internal resistance is lower. If shutdowns persist with a new pack, check that the battery contacts in the bay are clean and making full contact — verify pack voltage under load reads above 7.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426114601050,"sku":"BWCS-DLT300SL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426114633818,"sku":"BWCS-DLT300SL-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426114666586,"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\/maxkon-raytheon-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
