These are portable clinical devices that monitor blood oxygen saturation and heart rate. Voltage, capacity, and connector format match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOxitest 2000, Oxitest 7 Plus, and 3310-003 compatibility:\u003c\/strong\u003e\n    All three share the same 7.2V Ni-MH cell configuration and connector pinout. The BMS in each device reads cell voltage at startup against the same thresholds, so a single replacement pack covers all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on the Oxitest platform. The BMS accepted the cell, completed its self-test handshake, and drew current within the expected load profile across the SpO₂ sensing and display circuits.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this pack, let the device complete its full power-on self-test without interrupting or cycling power. The Oxitest BMS runs a voltage verification step at boot — cutting power mid-sequence writes a battery fault flag that will persist until the next complete cold 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 a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH cell arrives at a partial state of charge — typically between 40% and 60%. The Oxitest boot sequence includes a voltage check that compares cell voltage against the OEM minimum threshold. If the cell hasn't been fully charged first, the device may halt mid-boot or loop back to the startup screen. Charge the pack to full before powering the device on for the first time. After that initial full charge, the boot sequence completes normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS chemistry calibration issue, not a cell fault. The Oxitest charge IC sets its alarm threshold based on internal resistance and voltage curves it learned from the previous cell — a fresh Ni-MH pack has different characteristics until it's been cycled. Run one complete charge-discharge cycle before clinical use. After that cycle, the device's fuel gauge recalibrates to the new cell and the alarm clears at the correct threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381375336538,"sku":"BWCS-DTR200MD-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381375369306,"sku":"BWCS-DTR200MD-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381375402074,"sku":"BWCS-DTR200MD-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DTR200MD-1.webp?v=1778900351","url":"https:\/\/batteryweb.com\/products\/quest-oxitest-2000-replacement-battery-72v-2200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
