These instruments are used in industrial and laboratory environments to calibrate pressure, temperature, and electrical signals in the field. The pack ships against OEM part number 175-8013 and fits the 8081785 battery slot directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMC6 and MC6-WS compatibility:\u003c\/strong\u003e\n    Both variants share the same 11.1V three-cell Li-Polymer architecture, battery connector, and BMS handshake protocol. The same pack services both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through simulated pressure and temperature module initialisation sequences. The BMS held stable across probe power-up current spikes and sustained the 11.1V rail through multi-channel logging sessions without cutoff events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration cycle:\u003c\/strong\u003e\n    After installing this pack, run a full calibration cycle through the MC6 instrument menu before field deployment. The instrument maps battery state during that routine — skipping it causes premature low-battery warnings on the first real measurement session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the MC6 sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells in calibrators stored without regular top-up can drop below the BMS recovery threshold — typically around 2.5V per cell. When that happens, the BMS enters a protective lockout state and the instrument will not power on or accept a charge signal. Connecting the charger and leaving it for 30–60 minutes without forcing a power-on attempt allows the charger to trickle current through the protection circuit and bring the pack back above the recovery floor. If the pack responds, the instrument will resume normal charging from around 9V total and climb to full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMC6 shutting down mid-measurement with the battery gauge showing charge remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag issue, not a capacity issue. When the MC6 drives multiple sensor modules simultaneously — pressure transducer excitation plus thermocouple input plus display backlight — the combined draw creates a brief voltage dip that trips the BMS undervoltage threshold even though the gauge reads partial charge. An aged or partially degraded cell cannot sustain the voltage rail under that combined load. Replacing the pack resolves the cutoff; the new cells hold the rail above the BMS trip point under full sensor load. Confirm the fix by running the MC6 with all active modules simultaneously and checking that the voltage stays above 10.2V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360435175514,"sku":"BWCS-BMC600SL-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360435208282,"sku":"BWCS-BMC600SL-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360435241050,"sku":"BWCS-BMC600SL-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BMC600SL-1.webp?v=1778614684","url":"https:\/\/batteryweb.com\/products\/beamex-8081785-replacement-battery-111v-4200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
