It fits the 500A, 800, 515A, and additional units in this monitoring series. The battery restores portable operation for blood oxygen saturation and heart rate monitoring when the original cell has degraded or failed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e2001 Pulse Ox \/ 500A \/ 800 \/ 515A platform fit:\u003c\/strong\u003e\n    These units share the same 12V sealed lead-acid battery bay, internal connector pinout, and charge management circuitry. Swapping across models in this series does not require any adapter or hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through a full charge-discharge cycle on the 2001 platform. The onboard BMS accepted the cell without fault flags, completed charge termination correctly, and passed the low-battery threshold checks at expected voltage points.\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 device complete its full startup self-test sequence without interrupting power. The NOVAMETRIX charge IC runs a BMS verification pass at boot — cutting power during that window generates a persistent battery fault that does not clear 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 on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSealed lead-acid cells leaving storage often sit below 12.0V. The NOVAMETRIX BMS applies a minimum voltage threshold during the boot self-test — cells below roughly 11.8V can trigger an incomplete initialisation before the charge cycle has had time to recover them. If the device stalls mid-boot, connect it to mains and allow a full charge before attempting to power on again. A resting voltage of 12.6V or above confirms the cell is ready for the boot sequence to complete cleanly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe NOVAMETRIX charge controller applies a conservative current limit on the first charge cycle with a new sealed lead-acid cell. This is normal — the charge IC does not yet have a learned capacity baseline for the replacement cell. The indicator typically reaches full on the second charge cycle once the controller has logged a complete charge-discharge profile. Run one full discharge under normal monitoring load, then recharge fully before relying on the percentage display for clinical use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381384380506,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381384413274,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381384446042,"sku":"BWCS-SHT160MD-3","price":415.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHT160MD-1.webp?v=1778900511","url":"https:\/\/batteryweb.com\/products\/novametrix-medical-2001-pulse-ox-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
