These are portable point-of-care blood testing devices used in hospitals, emergency departments, and clinics. Capacity is 6.3Wh, matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ei-STAT 1, 300-G, and AN-500 compatibility:\u003c\/strong\u003e\n    All three models share the same 9V Ni-MH cell format, connector pinout, and BMS handshake protocol. A single cell swap covers the full platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the i-STAT power-on self-test sequence and confirmed the BMS completed its verification pass without triggering a false fault. Charge acceptance was normal from the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the analyzer complete its full power-on self-test without interruption. The i-STAT BMS runs a battery verification routine at startup — cutting power during this window logs a persistent fault that does not clear 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\"\u003eBMS learn cycle on the i-STAT after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe i-STAT charge controller was calibrated to an aged OEM cell, not a fresh one. A new Ni-MH cell has a slightly different internal resistance profile during the first five to ten charge cycles. Until the BMS has logged enough cycle data on the new cell, it may apply conservative charge termination and report capacity lower than actual. Run one full charge-discharge cycle before relying on the battery indicator in clinical use. Capacity readings stabilise after that initial conditioning period.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stuck below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge after installation, the i-STAT charge IC applies a delta-V cutoff tuned to a cell with some cycle history — a fresh Ni-MH cell's voltage curve is steeper, and the IC terminates early. The display may show 85–90% even after a full charge duration. This is not a cell fault. Complete one full discharge down to the low-battery cutoff, then recharge fully, and the indicator will track correctly from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381430288474,"sku":"BWCS-ABN500MD-1","price":65.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43381430321242,"sku":"BWCS-ABN500MD-2","price":77.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43381430354010,"sku":"BWCS-ABN500MD-3","price":86.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABN500MD-1.webp?v=1778900750","url":"https:\/\/batteryweb.com\/products\/abbott-i-stat-1-replacement-battery-9v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
