It powers the meter's display, test strip reader, and onboard processor. Voltage and capacity match the original spec: 3.7V and 6.66Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAccu-Chek Inform platform fit:\u003c\/strong\u003e\n    The Inform meter uses a fixed 3.7V single-cell architecture with a BMS that validates cell chemistry at startup. This cell matches that voltage rail and connector orientation, so the BMS handshake completes without a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Inform's startup self-test sequence and monitored BMS response across charge and discharge. The protection circuit handled both the low-draw display load and the brief current spike during test strip analysis without tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test handling:\u003c\/strong\u003e\n    After installing this cell, let the device complete its full power-on self-test without interruption. The Inform runs a BMS verification pass at boot — cutting power mid-sequence logs a false battery fault that persists until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Accu-Chek Inform alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Inform's BMS uses a learned capacity model calibrated to the original OEM cell chemistry. A new replacement cell hasn't yet passed the meter's internal capacity verification threshold, so the alarm triggers even when the cell is fully charged. This isn't a fault with the cell — it's the BMS comparing measured impedance against a stored OEM baseline it hasn't updated yet. Run one complete charge-discharge cycle and the BMS recalibrates; the alarm clears on its own after that cycle completes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAccu-Chek Inform not powering on after the cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-ion cells self-discharge during storage, and if the voltage drops below approximately 2.5V, the Inform's BMS enters a protection lockout and blocks startup entirely. The device will show no response — no display, no boot screen. Place the battery on a compatible external charger to bring the cell voltage above 3.0V before reinserting it into the meter. Once above that threshold, the BMS releases the lockout and the Inform boots normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381413085274,"sku":"BWCS-RCH300MD-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381413118042,"sku":"BWCS-RCH300MD-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381413150810,"sku":"BWCS-RCH300MD-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RCH300MD-1.webp?v=1778900625","url":"https:\/\/batteryweb.com\/products\/roche-accu-chek-inform-blood-glucose-monitoring-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
