It matches the original voltage rail, connector, and BMS communication protocol required by this clinical equipment. Capacity is 3400mAh (37.74Wh), identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMSCPR-1A platform fit:\u003c\/strong\u003e\n    The MSCPR-1A runs a dedicated BMS handshake at startup that checks cell chemistry and voltage signature. This cell matches the 11.1V three-cell Li-ion configuration the device expects, so the handshake completes without a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge, full load discharge, and BMS re-initialisation on the MSCPR-1A platform. The protection circuit responded correctly to load transitions and the charge IC accepted the cell without error codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full power-on self-test without interruption. The MSCPR-1A runs a BMS verification sequence at boot — cutting power mid-sequence trips a false battery fault that persists until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MSCPR-1A runs a multi-stage BMS verification during boot that checks cell voltage, internal resistance, and chemistry ID. A new cell fresh from storage may sit at a resting voltage slightly outside the range the device expects on first power-on, causing the boot sequence to stall or loop. This is not a defective cell — it is the device's safety logic rejecting an unverified cell. Connect the charger, allow a full charge cycle to complete, then power on again.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MSCPR-1A sets its low-battery alarm threshold against a calibrated capacity baseline stored in the BMS. On a new cell, the BMS has no learned baseline yet, so it defaults to a conservative threshold that can trigger the alarm even when the cell is fully charged. One complete charge-discharge cycle gives the BMS enough data to recalibrate the threshold. Run that cycle before placing the device back in clinical rotation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381446344794,"sku":"BWCS-MDS100MX-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381446377562,"sku":"BWCS-MDS100MX-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381446410330,"sku":"BWCS-MDS100MX-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDS100MX-1.webp?v=1778900876","url":"https:\/\/batteryweb.com\/products\/medsonic-mscpr-1a-replacement-battery-111v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
