It replaces OEM part numbers 110261, 3088-000 Rev B, and OM11320. The Palm Sat 2500 measures blood oxygen saturation and pulse rate — clinical and home-care settings both rely on this battery staying functional.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePalm Sat 2500 fit confirmation:\u003c\/strong\u003e\n    The SAT 2500 platform runs a 4.8V NiMH pack with a specific connector orientation and cell arrangement. This battery matches that physical layout and voltage rail exactly — the BMS handshake completes without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the Palm Sat 2500's charge and discharge sequence. The BMS accepted the cell, completed its initialisation, and the device passed its power-on self-test without triggering a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test procedure:\u003c\/strong\u003e\n    After installing this battery, allow the Palm Sat 2500 to complete its full power-on self-test without interruption. The device runs a BMS verification cycle at startup — cutting power during this sequence stores a false battery fault that persists 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\"\u003ePalm Sat 2500 alarming low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Palm Sat 2500's BMS was calibrated against an aged OEM cell with a known internal resistance profile. A fresh NiMH cell has lower internal resistance, which causes the BMS to read the charge state as out-of-range on the first cycle. The device triggers a low-battery alarm even though the cell is fully charged. Run one complete charge-discharge cycle and the BMS recalibrates — the alarm clears and readings normalise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells self-discharge during storage — if this battery has been on a shelf for several months, the resting voltage may have dropped below the Palm Sat 2500's BMS recovery threshold. The BMS refuses to boot the device rather than attempt to run on an under-voltage cell. Place the battery on charge for a full uninterrupted cycle before attempting to power on. If the charge indicator stays dark past the first 10 minutes, the cell voltage has dropped below 1.0V per cell — leave it on charge for a minimum of 16 hours before re-testing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381368160346,"sku":"BWCS-NAT250MD-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381368193114,"sku":"BWCS-NAT250MD-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381368225882,"sku":"BWCS-NAT250MD-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NAT250MD-1.webp?v=1778900303","url":"https:\/\/batteryweb.com\/products\/nonin-palm-sat-2500-pulse-oximeter-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
