It powers the memory and data-logging functions that the device relies on during patient monitoring. When the original cell depletes, this replacement restores those functions using the same voltage, chemistry, and form factor.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIII 2865 Memory platform fit:\u003c\/strong\u003e\n    The III 2865 Memory uses Li-SOCl2 specifically because the chemistry holds a flat discharge curve across low self-discharge storage periods — critical for a device that may sit unused between clinical sessions. The 3V nominal and physical dimensions (45.95 × 20.00 × 17.00mm) match the original cell specification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the III 2865 Memory's startup sequence and confirmed the BMS completed its initialisation pass. The cell delivered stable voltage throughout the self-test cycle with no mid-sequence dropout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this cell, allow the device to complete its full power-on self-test without interruption. The III 2865 Memory runs a BMS verification at startup — cutting power during this sequence triggers a false battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy Li-SOCl2 chemistry behaves differently after storage in medical devices\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-SOCl2 cells can develop a passivation layer on the lithium anode during storage. This layer causes a brief voltage dip when the cell is first loaded — sometimes enough to trigger a low-battery alarm even on a fresh cell. The layer dissipates within the first few load cycles. If the III 2865 Memory alarms immediately after installation, this is the likely cause, not a faulty cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence after cell replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the III 2865 Memory stalls mid-boot after a cell swap, the BMS may have logged a voltage fault from the passivation dip described above. Power the device off completely, wait 30 seconds, then restart to allow a clean initialisation pass. If the fault persists, check that the cell contacts are fully seated — the 45.95mm cell length means a partial insertion can cause intermittent contact. A full, uninterrupted boot at room temperature clears most reported startup faults.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381471576154,"sku":"BWCS-AMS286MD-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381471608922,"sku":"BWCS-AMS286MD-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381471641690,"sku":"BWCS-AMS286MD-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMS286MD-1.webp?v=1778901050","url":"https:\/\/batteryweb.com\/products\/med-system-iii-2865-memory-replacement-battery-3v-2200mah-li-socl2","provider":"BatteryWeb","version":"1.0","type":"link"}
