It restores cordless operation during patient examinations in clinical settings. OEM part numbers include 120260, BATT\/110260, and 7741715, among others listed against this unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eECG Delta 60 and Delta 60Plus compatibility:\u003c\/strong\u003e\n    Both variants share the same 24V power rail, connector format, and BMS handshake protocol, which is why a single cell fits the full range. The physical dimensions — 87.50 x 68.00 x 87.90 mm — match the battery bay on both chassis without modification.\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 Delta 60 platform and confirmed the BMS accepted the cell without triggering a fault flag. The protection circuit responded correctly to load variation during the simulated ECG acquisition cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, allow the Delta 60 to complete its full power-on self-test without interruption. Medical-grade BMS firmware runs a verification routine at startup, and cutting power mid-sequence stores a false battery fault that will persist 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 Delta 60 BMS rejects a new Ni-MH cell on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Delta 60 charge IC applies chemistry-specific threshold checks inherited from the OEM cell's calibration history. A fresh Ni-MH cell has no learned capacity data in the BMS register, so the controller defaults to a conservative acceptance window. This can cause the charge indicator to stall before reaching 100% on the first cycle. Running one complete charge-discharge cycle allows the BMS to build a capacity baseline and unlocks normal charge termination on subsequent cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off mid-examination despite showing adequate charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Delta 60 draws a sharp current spike during ECG signal acquisition, and in the first ten cycles a new Ni-MH cell shows higher internal resistance than a conditioned one. That resistance causes a momentary voltage sag that the BMS reads as an undervoltage event and triggers a protective shutdown. This is not a faulty cell — it is the BMS responding to a transient load the cell has not yet conditioned against. Complete three to five full charge-discharge cycles before using the device in a clinical examination context; internal resistance drops measurably by cycle four.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381492351066,"sku":"BWCS-CAR600MD-1","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381492383834,"sku":"BWCS-CAR600MD-2","price":123.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381492416602,"sku":"BWCS-CAR600MD-3","price":136.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CAR600MD-1.webp?v=1778901248","url":"https:\/\/batteryweb.com\/products\/cardioline-ecg-delta-60-replacement-battery-24v-1300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
