These portable vital signs monitors are used in hospitals for bedside care and patient transport. The battery slots into the monitor's battery bay and restores untethered operation when the original cell has degraded.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGamma XL and Vista platform compatibility:\u003c\/strong\u003e\n    The Infinity Gamma XL, EPP130, and WP1250 share the same 12V Ni-MH battery architecture, battery bay form factor, and BMS connector pinout. One cell covers all three models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through full charge and discharge cycles on the Infinity platform. The BMS accepted the cell, completed handshake verification, and charge indicators progressed normally. No false fault codes were triggered.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, let the monitor complete its full power-on self-test cycle without interruption. Draeger patient monitors run BMS verification at startup — cutting power during this sequence stores 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\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Infinity platform runs a BMS learn cycle during first boot on a new cell. If the monitor stalls mid-boot or loops back to the startup screen, the BMS has not yet logged the new cell's charge profile. This is not a faulty battery — it is the monitor's charge IC applying conservative startup logic to an unverified cell. Fit the battery, connect AC power, and allow one uninterrupted full charge before powering the monitor on. After that first full charge, the boot sequence completes normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first installation, the Draeger charge IC applies a conservative upper limit to the new cell — the indicator may stall at 85–95% and not advance further. This happens because the BMS has not yet confirmed the cell's internal resistance profile and caps input current as a safety measure. It is not a cell defect. Run one complete charge-discharge-charge cycle and the charge IC recalibrates; subsequent charges reach 100% as expected.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381467971674,"sku":"BWCS-CBP308MD-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381468004442,"sku":"BWCS-CBP308MD-2","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381468037210,"sku":"BWCS-CBP308MD-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CBP308MD_1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/draeger-infinity-gamma-xl-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
