These are portable clinical monitors used for continuous vital signs monitoring during patient transport and bedside assessments. It replaces OEM part number B10782 directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM1722 and M1723 series compatibility:\u003c\/strong\u003e\n    These monitors share the same 12V battery bay, connector pinout, and BMS handshake protocol across the A, B, and XE variants. One battery fits all listed models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and load cycles on the M1722B platform. The BMS accepted the cell on first connection, completed its initialisation routine, and held voltage within spec under simulated clinical load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the monitor complete its full power-on self-test without interrupting it. The device runs a BMS verification sequence at startup — cutting power mid-cycle logs a false battery fault that will persist until the next clean full reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the M1722B reports a battery fault after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe M1722B BMS stores a capacity baseline from the previous cell. A new sealed lead-acid cell has a slightly different internal resistance profile than a degraded OEM battery, and the BMS interprets this as a fault condition on first boot. This is not a defective cell — it is the BMS comparing the new cell against a stale reference. Run one complete charge-discharge cycle and the BMS recalibrates its threshold. After that cycle, fault codes tied to the old baseline clear automatically.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stuck below 100% after first full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSealed lead-acid charge ICs apply a conservative current limit on the first charge cycle of a new cell. The M1722 series charge controller reads this reduced acceptance current as incomplete charge and stops the indicator short of 100%. This is a first-cycle artefact, not a capacity problem. Run the battery down to the device's low-battery threshold and then charge it fully — the indicator will reach 100% and hold there on subsequent cycles.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381512405082,"sku":"BWCS-PHM172MD-1","price":122.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381512437850,"sku":"BWCS-PHM172MD-2","price":144.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381512470618,"sku":"BWCS-PHM172MD-3","price":160.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHM172MD-1.webp?v=1778901340","url":"https:\/\/batteryweb.com\/products\/philips-m1722ab-replacement-battery-12v-4500mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
