It fits the 1000E platform used in cardiac catheterization labs for continuous pulse oximetry monitoring. OEM part references 12140S, 6060, and B11406 all apply to this battery position.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAvoximeter 1000E platform fit:\u003c\/strong\u003e\n    The 1000E series runs a single 4.8V Ni-MH pack with a dedicated BMS handshake that verifies cell chemistry at boot. Swapping to a matched 4.8V Ni-MH cell keeps that handshake intact. Voltage mismatches or Li-ion substitutes will trigger a persistent battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the 1000E's charge IC and confirmed the BMS accepted the chemistry flag on the first full charge. The protection circuit held cutoff at 5.52V charge ceiling and 4.0V discharge floor without tripping an error state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test procedure:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full power-on self-test without interrupting it. The 1000E runs a BMS verification sequence at startup. Powering off mid-sequence logs a false battery fault that stays flagged until the next clean reboot with a fully charged cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Avoximeter 1000E alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 1000E's charge controller uses a stored capacity baseline from the previous cell to set its low-battery threshold. A new Ni-MH cell starts with no baseline logged, so the BMS reads available capacity as below threshold even when the cell is fully charged. One complete charge-discharge cycle writes a new baseline into the controller's memory. After that first cycle, the low-battery alarm tracks correctly against the 2800mAh cell capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAvoximeter 1000E not powering on after the replacement battery 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. A cell that has sat more than a few weeks may drop below the 1000E's BMS recovery threshold — typically 3.6V for a 4.8V four-cell pack. At that voltage the BMS locks out the discharge path to prevent cell reversal damage. Connect the device to mains power and leave it charging uninterrupted for a full charge cycle. Most BMS units on this platform re-enable discharge once the pack reaches 4.2V during the recovery charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381425406042,"sku":"BWCS-AME100MD-1","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381425438810,"sku":"BWCS-AME100MD-2","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381425471578,"sku":"BWCS-AME100MD-3","price":54.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AME100MD-1.webp?v=1778900661","url":"https:\/\/batteryweb.com\/products\/avox-1000e-cath-lab-oximeter-replacement-battery-48v-2800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
