It slots into the same physical bay and connects through the same BMS interface as the original cell. Dimensions are 52.50 × 38.60 × 12.60mm — verify your bay before ordering if you are unsure which model you have.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-platform fit — CoaguChek and Accuchek series:\u003c\/strong\u003e\n    These models share the same battery bay geometry, connector pinout, and BMS communication protocol, which is why one cell covers the full range. Voltage rail is 3.7V nominal across all four platforms, so the BMS handshake behaves identically on each.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the POCT boot sequence and monitored BMS response during startup self-test. The battery passed the internal resistance check and held voltage above the low-battery alarm threshold through the full verification cycle without triggering a false fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after swap:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full startup self-test without interruption. Medical device BMS firmware runs a verification sequence at first power-on, and cutting power mid-cycle can register 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\"\u003eWhy the CoaguChek Pro II flags a battery fault on a brand-new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRoche's BMS firmware uses internal resistance as one threshold in its battery health check. A fresh cell that has not yet completed a full charge-discharge cycle can present a slightly elevated internal resistance reading — enough for the BMS to flag a caution state even though the cell is at full charge. This is not a defective battery. Run one complete charge-discharge cycle before clinical use and the resistance value settles into the accepted window. After that first cycle, the fault clears and does not return under normal use conditions.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge after installation, the Accuchek Inform II and CoaguChek platforms apply a conservative charge ceiling to new cells — the charge IC limits current in the final absorption phase until it has profiled the cell's capacity. The display may hold at 95–98% for an extended period before reaching full. This is normal charge IC behaviour, not a fault with the battery or charger. Let the charge cycle complete uninterrupted and the indicator will reach 100%; subsequent charges will complete normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381414789210,"sku":"BWCS-RCP200MD-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381414821978,"sku":"BWCS-RCP200MD-2","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381414854746,"sku":"BWCS-RCP200MD-3","price":72.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RCP200MD-1.webp?v=1778900625","url":"https:\/\/batteryweb.com\/products\/roche-poct-30645-00-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
