Both devices draw from the same 14.4V battery platform and use the same connector and BMS communication protocol. Capacity is 7800mAh (112.32Wh) as specified.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eElisee 250 and 350 compatibility:\u003c\/strong\u003e\n    Both models share the same 14.4V battery rail, physical form factor, and BMS handshake requirements. A single battery revision covers both units — no hardware modification needed between platforms.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and load cycles on the Elisee platform. The BMS completed handshake, the charge IC accepted the cell without faulting, and the unit held steady under the ventilator's variable pressure delivery load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the Elisee to complete its full power-on self-test without interruption. The device runs 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 the Elisee 250 may alarm low battery on a freshly charged replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Elisee's BMS compares cell voltage and internal resistance against thresholds calibrated for OEM chemistry. A new replacement cell hasn't completed a learn cycle yet, so its resistance profile can read outside the expected window on first use. The device interprets this as a degraded or low battery and triggers the alarm even at full charge. Running one complete charge-to-discharge cycle allows the BMS to establish a baseline and the alarm clears on subsequent use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eElisee not powering on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-ion cells self-discharge during storage. If this battery shipped or sat unused for an extended period, its voltage may have dropped below the Elisee's BMS recovery threshold — typically around 10.0–10.5V for a 14.4V pack. The BMS will refuse to engage the output circuit at this voltage to protect the cells. Connect the battery to its charger first and leave it for a minimum of two hours before attempting to power on the ventilator; recovery charging will bring it back above the engagement threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381480620122,"sku":"BWCS-RME150MD-1","price":119.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381480652890,"sku":"BWCS-RME150MD-2","price":138.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381480685658,"sku":"BWCS-RME150MD-3","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RME150MD-1.webp?v=1778901194","url":"https:\/\/batteryweb.com\/products\/resmed-elisee-250-replacement-battery-144v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
