It matches OEM part numbers 43.889.0209, 350-0149-BA, 70104.930, 90009008, and 701049130. Voltage and capacity align to OEM specification — 10.8V nominal, 84.24Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCARDIOHELP and PULMONAR CARDIOHELP platform fit:\u003c\/strong\u003e\n    Both units share the same battery bay geometry, BMS communication protocol, and 10.8V three-cell series configuration. The connector pinout and charge handshake are identical across the platform, so one cell replacement covers both listed models without hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the CARDIOHELP charge cycle and monitored BMS handshake at each stage. The protection circuit responded correctly to charge termination, over-current cutoff, and low-voltage recovery — all within OEM thresholds before we ship.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup procedure:\u003c\/strong\u003e\n    After installing this battery, let the CARDIOHELP complete its full power-on self-test without interruption. The BMS runs a verification sequence at boot — cutting power mid-test causes a false battery fault that persists until the next full reboot cycle, not the next charge.\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 first use in the CARDIOHELP\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CARDIOHELP BMS was calibrated to the charge and discharge curve of the OEM cell. A replacement cell with a fresh anode state behaves slightly differently in the first several cycles — the BMS capacity estimate drifts until it has mapped the new cell's actual curve. This appears as a fluctuating charge indicator or a state-of-charge reading that doesn't track linearly. Run one complete charge-to-full followed by a controlled discharge before placing the unit into clinical rotation — this closes the calibration gap and gives the BMS an accurate baseline.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on initial charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first charge after installation, the CARDIOHELP charge IC applies a conservative current limit to an uncharacterised cell — this causes the indicator to plateau at 90–95% and hold there longer than expected. The cell is not faulty and the charge circuit is not stuck. The IC completes a trickle-top phase before releasing the 100% indication. Allow the charge cycle to complete fully without disconnecting — the indicator will reach 100% once the charge IC confirms cell voltage has stabilised at 12.6V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381395456090,"sku":"BWCS-MAT029MD-1","price":212.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381395488858,"sku":"BWCS-MAT029MD-2","price":252.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381395521626,"sku":"BWCS-MAT029MD-3","price":282.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MAT029MD-1.webp?v=1778900536","url":"https:\/\/batteryweb.com\/products\/maquet-getinge-cardidiohelp-replacement-battery-108v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
