It replaces OEM part SE301120 and fits the full Respirateur Stellar range. If your device is showing a low-battery alarm during patient transport or a power outage, this is the direct replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStellar 100 and Stellar 150 compatibility:\u003c\/strong\u003e\n    Both models run the same 14.4V battery rail, use the same 4S1P cell configuration, and share an identical BMS handshake protocol — which is why one SKU covers both ventilator variants.\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 discharge cycles on the Stellar platform. The BMS completed its verification sequence, accepted the cell chemistry, and reported accurate state-of-charge across the full voltage range from 16.8V down to the 12V cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the Stellar complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power mid-cycle causes a false battery fault flag that will persist 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\"\u003eWhy the Stellar 150 may alarm low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Stellar's BMS compares measured cell impedance and resting voltage against a stored OEM chemistry profile. A new replacement cell hasn't completed its first conditioning cycle, so its internal resistance reads higher than the reference threshold. The device interprets this as a degraded or under-capacity battery and triggers the alarm even when state-of-charge is at 100%. Running one full charge-to-discharge cycle resolves the mismatch — the BMS recalibrates its internal model against actual cell behaviour and clears the alarm condition.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eStellar not completing boot sequence after 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 several months, resting voltage may have dropped below the Stellar's BMS recovery threshold — typically around 12.0V for a 4S pack. When terminal voltage is below this threshold, the device won't initiate a boot sequence at all; it simply stays dark. Connect the battery to the OEM charger first and allow a minimum 15-minute pre-charge before attempting to power on the ventilator. Once voltage climbs above 12.0V, the BMS unlocks and the device will boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381443297370,"sku":"BWCS-RME100MD-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381443330138,"sku":"BWCS-RME100MD-2","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381443362906,"sku":"BWCS-RME100MD-3","price":75.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RME100MD-1.webp?v=1778900853","url":"https:\/\/batteryweb.com\/products\/resmed-respirateur-stellar-150-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
