These handheld units are used for industrial diagnostics, building envelope inspections, and electrical system analysis. Capacity is 4200mAh (25.2Wh) — taken from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePalm IR 225 \/ 500 shared platform:\u003c\/strong\u003e\n    These models draw from the same 6V battery rail and use the same physical form factor and connector. The detector heating element, display backlight, and signal processing board all run off this single cell pack — which is why voltage stability across the discharge curve matters more here than in a standard camera.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge-discharge cycles on a Palm IR 225 unit. The BMS held cutoff voltage correctly under combined detector-plus-display load, and cell balance across the Ni-MH stack stayed within spec through repeated cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation warm-up on the Palm IR 225:\u003c\/strong\u003e\n    Allow the camera to run for 60 seconds after power-on before taking any thermal readings. The uncooled detector array needs the internal electronics to reach a stable baseline temperature — readings taken immediately after startup will show calibration drift and inaccurate delta-T values.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eThermal camera shutting down mid-inspection on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Palm IR 225 draws current from three simultaneous loads: the detector heating element, the LCD display, and the onboard processing electronics. At peak draw — typically when the display refreshes a high-contrast thermal scene — the combined current spike can trigger the BMS protection circuit even when nominal charge looks healthy. This is not a faulty battery; it is a protection trip caused by instantaneous load exceeding the pack's rated discharge threshold. If this happens, power off fully, wait 10 seconds, and restart — the BMS resets on a clean power cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eThermal image accuracy degrading before the low-battery indicator appears\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Palm IR 225's detector array is voltage-sensitive — as cell voltage sags under load, the detector's internal reference signal shifts slightly, which shows up as reduced thermal contrast and inaccurate temperature readings before the camera's firmware triggers a low-battery warning. The low-battery threshold is calibrated to cell voltage at rest, not under detector load. If readings start drifting or hot spots look cooler than expected, check voltage under load — below 5.4V under active detector draw, swap the battery rather than continuing the inspection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426125348954,"sku":"BWCS-TPM280SL-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426125381722,"sku":"BWCS-TPM280SL-2","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426125414490,"sku":"BWCS-TPM280SL-3","price":72.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TPM280SL-1.webp?v=1779930385","url":"https:\/\/batteryweb.com\/products\/raytheon-raytheon-palm-ir-225-replacement-battery-6v-4200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
