These instruments share a common battery bay format and voltage rail across the platform. Capacity is sourced from product data at 3400mAh (36.72Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShared platform compatibility — MIRA XTR, MIRA P, NanoRAM, TacticID:\u003c\/strong\u003e\n    These four Raman spectrometers use the same 10.8V three-cell Li-ion configuration, matching connector footprint, and compatible BMS handshake protocol. Swapping across models in this family works because the instruments draw from the same voltage rail and expect the same cell-group reporting.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack against a simulated MIRA XTR load profile, including the current spike at laser module initialisation. The BMS held without tripping, and cell voltage balanced correctly through a full discharge-recharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on Raman instruments:\u003c\/strong\u003e\n    After installing a new pack, run a full instrument calibration cycle through the system menu before taking field measurements. The MIRA XTR maps battery state during calibration — skipping this step causes premature low-battery warnings to appear during your first measurement session, even with a fully charged pack.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff at laser module power-up on the MIRA XTR\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MIRA XTR fires its laser module during instrument initialisation, and this draw spike is the single largest current event the battery sees. A degraded or cold cell pack can't hold voltage through that spike, and the BMS interprets the sag as an undervoltage fault — cutting power before a scan begins. This replacement pack is spec'd to handle that initialisation surge without triggering cutoff. If the instrument shuts off at the exact moment the laser arms, check that cell voltage is above 10.5V before powering on in cold conditions.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePack not recognised after the instrument sat unused for several months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that sit discharged below approximately 9V will cause the BMS to enter a deep-sleep protection state. When you insert the pack and press power, the instrument sees no valid battery signal and either ignores it or shows a battery error. Connect the charger before attempting to power on — most BMS circuits will accept a trickle recovery charge and exit sleep mode within 15–30 minutes. Once cell voltage climbs back above 10.0V, the instrument will recognise the pack and boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360453722202,"sku":"BWCS-FBP290SL-1","price":403.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360453754970,"sku":"BWCS-FBP290SL-2","price":483.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360453787738,"sku":"BWCS-FBP290SL-3","price":542.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FBP290SL-1.webp?v=1778614684","url":"https:\/\/batteryweb.com\/products\/metrohm-mira-xtr-replacement-battery-108v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
