It powers the device's compressor and oxygen generation system during mobile patient use. OEM part numbers 120140 and BATT\/110140 both cross to this replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOxipac 2500 pack compatibility:\u003c\/strong\u003e\n    The Oxipac 2500 uses a specific 9.6V Ni-MH cell configuration to match the BMS voltage thresholds built into the concentrator's control board. Swapping chemistry or voltage causes immediate BMS rejection — this pack holds the correct cell count and connector pinout for the platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the Oxipac 2500's charge and discharge sequence. The BMS accepted the pack without fault codes, completed its self-test, and held voltage above the low-battery cutoff threshold across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this pack, allow the device to complete its full power-on self-test without interruption. The Oxipac 2500 runs a BMS verification routine at startup — cutting power mid-sequence triggers a false battery fault that won't clear until the next 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 Oxipac 2500 may alarm low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Oxipac 2500's BMS uses chemistry-calibrated voltage thresholds to determine charge state. A new Ni-MH cell that hasn't completed its first full charge-discharge cycle sits slightly below the BMS's accepted charge curve, which the device reads as insufficient charge rather than a new cell. This isn't a fault with the battery — it's the BMS applying its OEM-calibrated acceptance window. Run one complete charge and discharge cycle before clinical use, and the alarm clears on subsequent charges.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after replacement pack sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day in storage. If this pack has been on a shelf for several months, its resting voltage may have dropped below the Oxipac 2500's BMS recovery threshold — typically around 7.2V for a 9.6V pack — causing the device to refuse to boot. Connect the pack to the charger for a full uninterrupted charge cycle before attempting to power the device. If the charger shows activity and completes normally, the BMS has recovered the pack and the device will start.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381492613210,"sku":"BWCS-DRX250MD-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381492645978,"sku":"BWCS-DRX250MD-2","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381492678746,"sku":"BWCS-DRX250MD-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRX250MD-1.webp?v=1778901265","url":"https:\/\/batteryweb.com\/products\/drager-oxipac-2500-replacement-battery-96v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
