It replaces OEM part 080860-010 and fits the MP-ΣNⅡ, MP-Σ300NⅡ, MP-Σ500NⅡ, and MP-Σ100HNⅡ. At 32.56Wh, it matches the original capacity the instrument expects for accurate power management.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMP-ΣNⅡ series compatibility:\u003c\/strong\u003e\n    These models share the same 7.4V power rail, connector pinout, and BMS handshake protocol. One battery pack covers the full variant range 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 probe initialisation and sustained logging draws. The BMS held stable across the sensor power-up spike and did not trip during continuous measurement sessions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-deployment calibration cycle:\u003c\/strong\u003e\n    After installing, run a full calibration cycle through the instrument menu before field deployment. The MP-ΣNⅡ maps battery state during calibration — skipping this step causes premature low-battery warnings on the first measurement session in the field.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff when the MP-ΣNⅡ probe module powers up\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eProbe initialisation on the MP-ΣNⅡ series draws a short current spike as the sensor module powers its internal circuitry. If the battery's BMS protection threshold is set too conservatively, this spike triggers an overcurrent cutoff before the instrument reaches the measurement screen. This pack's BMS is rated to handle the initialisation transient without interruption. If cutoff still occurs on first use, allow the pack to rest at full charge for 10 minutes before powering on — this lets cell voltage stabilise above 8.2V open-circuit.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eInstrument powers on but shuts down during USB data transfer to PC\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUSB data transfer adds a second sustained draw on top of the active sensor load — together they can pull enough current to trip a marginal or partially depleted pack. This is not a software fault; it is a voltage sag issue. If the instrument cuts out during transfer, charge the battery to full before attempting a data dump. A healthy pack at full charge should hold above 7.0V under combined USB and sensor load throughout the transfer.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360455000154,"sku":"BWCS-SBM300SL-1","price":83.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43360455032922,"sku":"BWCS-SBM300SL-2","price":99.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43360455065690,"sku":"BWCS-SBM300SL-3","price":110.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SBM300SL-1.webp?v=1778615900","url":"https:\/\/batteryweb.com\/products\/sibata-mp-%cf%83n%e2%85%b1-replacement-battery-74v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
