It replaces OEM part number 4032-0003. The BCI 7500 is a portable clinical device used for non-invasive blood oxygen saturation and heart rate monitoring.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBCI 7500 compatibility:\u003c\/strong\u003e\n    The 7500 series uses a 7.2V Ni-MH cell pack with a specific connector and BMS handshake tied to that chemistry. This battery matches the voltage rail and connector pinout the device expects — a voltage or chemistry mismatch causes immediate low-battery alarm at startup.\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 BCI 7500 platform. The BMS accepted the pack without fault codes, completed its self-test sequence, and held load through simulated monitoring sessions across the first five cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the BCI 7500 complete its full power-on self-test without interrupting the boot sequence. The device runs a BMS verification at startup — cutting power during this window logs a false battery fault that persists until the next complete 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 BCI 7500 triggers a low-battery alarm with a new fully charged pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BCI 7500's charge management IC sets its pass threshold based on the internal resistance profile of a conditioned OEM cell. A fresh replacement cell has higher internal resistance before its first few cycles, which the BMS reads as a partially depleted pack. This causes the device to alarm low battery even when the replacement is at full charge. Running one complete charge-discharge cycle lowers the cell's internal resistance enough for the BMS to recognise it as a healthy pack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBCI 7500 will not power on after the battery sat unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage. If the pack voltage dropped below the BCI 7500's BMS recovery threshold — typically around 5.4V for a 7.2V pack — the protection circuit locks out the battery to prevent damage. The device will show no response at the power button. Place the battery on an external Ni-MH charger first, bring it above 6V, then reinstall and power on the device.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381460861018,"sku":"BWCS-NAT750MD-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381460893786,"sku":"BWCS-NAT750MD-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381460926554,"sku":"BWCS-NAT750MD-3","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NAT750MD-1.webp?v=1778900984","url":"https:\/\/batteryweb.com\/products\/bci-7500-pulse-oximeter-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
