These are clinical-grade portable devices used to measure oxygen concentration in gas mixtures. This cell matches the original voltage rail and chemistry to keep the device operating correctly in healthcare and laboratory environments.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOxitest 2000, 7 Plus, and 3310-003 platform fit:\u003c\/strong\u003e\n    These three models share the same 7.2V Ni-MH power architecture, connector pinout, and BMS handshake protocol — which is why one replacement cell covers all three.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Oxitest power-on sequence and confirmed the BMS accepted the new cell without triggering a chemistry mismatch fault. Charge termination and delta-V cutoff behaved correctly across the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the device to complete its full power-on self-test without interrupting it — the Oxitest BMS runs a chemistry verification at startup, and cutting power mid-sequence stores 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\"\u003eDevice not completing boot sequence on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Oxitest platform runs a BMS learn cycle during its first boot after a battery swap. If the cell voltage is slightly below the device's startup acceptance threshold — common after shipping — the analyzer may halt mid-boot and display a battery fault. Charge the new cell fully before the first installation, not after. Once the cell reaches full charge, the boot sequence completes and the BMS registers the new pack correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Oxitest charge IC applies a conservative current limit on cells it hasn't yet profiled. On a fresh Ni-MH pack, this means the first charge often terminates early — the indicator stalls at 80–90% and the device reports it as fully charged. This is the charge IC being cautious, not a fault with the cell. Run one full charge-to-discharge-to-charge cycle and the IC recalibrates its delta-V endpoint to the actual cell capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381375434842,"sku":"BWCS-DTR200MD-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381375467610,"sku":"BWCS-DTR200MD-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381375500378,"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\/dynatech-oxitest-2000-replacement-battery-72v-2200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
