It fits the 930 Oximeter, 900S-10, 970SE-10 Smart Monitor, and 900S among others. Voltage and capacity match OEM spec exactly — 6V, 4000mAh, 24Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e930 series and 970SE compatibility:\u003c\/strong\u003e\n    These models share a common 6V battery rail, identical connector pinout, and the same BMS handshake protocol. One battery fits across the platform because the charge management IC expects the same cell chemistry and voltage curve throughout the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge-discharge cycles on a 930 Oximeter. The BMS accepted the new cell without fault flags, completed self-test, and held voltage within spec under continuous SpO2 monitoring load across 10 cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap power-on sequence:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full power-on self-test without interrupting it. The 930 series runs a BMS verification step at every startup — cutting power during that window logs a battery fault that won't 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\"\u003eWhy the 930 Oximeter flags a battery fault on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 930's charge IC uses a delta-V detection algorithm tuned to an aged OEM cell's charge curve. A fresh Ni-MH cell has a steeper voltage rise on first charge, which the IC can misread as a fault condition. This typically clears after one complete charge-discharge cycle, because the cell's internal resistance settles and the voltage profile normalises. Run a full cycle before putting the device into clinical rotation — the fault flag won't return after that.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shows full charge but alarms low battery within minutes of use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS has not yet calibrated its state-of-charge reference against the new cell's capacity. The charge gauge was built around a cell that had degraded over years of cycling — a fresh 4000mAh cell reads differently until the controller re-learns the curve. Run one full discharge down to automatic cutoff, then charge uninterrupted to 100%. After that cycle, the state-of-charge reading will track accurately against actual capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381509390426,"sku":"BWCS-HPS930MD-1","price":72.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381509423194,"sku":"BWCS-HPS930MD-2","price":84.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381509455962,"sku":"BWCS-HPS930MD-3","price":93.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPS930MD-1.webp?v=1778901339","url":"https:\/\/batteryweb.com\/products\/respironics-930-oximeter-replacement-battery-6v-4000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
