It replaces OEM part numbers 5790224 and SE301151. The Oxylog VE300 is a medical-grade transport ventilator used in emergency and clinical settings where uninterrupted ventilation support is critical.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOxylog VE300 platform fit:\u003c\/strong\u003e\n    The VE300 uses a specific connector pinout and BMS handshake tied to this cell configuration. The 11.1V three-cell series arrangement matches the device's internal power rail, and the BMS communicates state-of-charge data directly to the ventilator's battery management display. Substituting a different cell configuration breaks that communication.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through the VE300's full power-on self-test sequence. The BMS passed state-of-charge verification, the charge IC accepted a full cycle without fault codes, and the device's low-battery threshold did not trigger prematurely under simulated clinical load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use startup on the VE300:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full power-on self-test without interruption. The VE300's BMS runs a chemistry verification step at startup — cutting power during this sequence locks in a false battery fault that persists until the next clean reboot from full charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VE300 alarms low battery with a freshly charged replacement installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Oxylog VE300 sets its low-battery alarm threshold against a learned charge profile from the BMS. A new cell has not yet completed a full charge-discharge cycle, so the BMS reports a state-of-charge value that sits below the device's calibrated threshold — even when the cell is physically full. This is not a faulty battery. One complete charge-discharge cycle recalibrates the BMS, and the alarm clears on subsequent use. Do not deploy the battery in clinical rotation until that first cycle is finished.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVE300 not completing boot sequence after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the VE300 halts mid-boot after a swap, the most common cause is a cell that has self-discharged below the BMS recovery threshold during storage — typically under 9V per pack. The device's startup routine draws an immediate load to verify supply stability, and a deeply discharged cell cannot hold voltage under that draw. Connect the battery to the OEM charger and allow a full charge cycle before attempting to power the device on. Once the pack reads above 10.5V resting voltage, the boot sequence completes normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381400895578,"sku":"BWCS-DRE300MD-1","price":275.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381400928346,"sku":"BWCS-DRE300MD-2","price":329.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381400961114,"sku":"BWCS-DRE300MD-3","price":369.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRE300MD-1.webp?v=1778900536","url":"https:\/\/batteryweb.com\/products\/drager-oxylog-ve300-replacement-battery-111v-5600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
