It fits directly using OEM part references 4.350044, 88881115, and 110650-O. Capacity is sourced from product data — 31.08Wh total energy, matched to the MS-2007 voltage rail.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCardiovit MS-2007 compatibility:\u003c\/strong\u003e\n    The MS-2007 uses a single Li-Polymer cell pack at 7.4V nominal. The BMS handshake checks cell chemistry and voltage at startup — this replacement matches both parameters, so the device completes its power-on self-test without throwing a battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and load discharge on the MS-2007 platform. The BMS registered a valid cell on the first connection. Charge termination triggered correctly at full voltage without overcharge flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the MS-2007 to complete its full power-on self-test cycle without interruption. Cutting power during that sequence can latch a false battery fault in the BMS that persists until the next clean reboot — not a cell fault, just an incomplete handshake.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MS-2007 flags a battery error after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Cardiovit MS-2007 BMS stores a learned capacity profile from the previous cell. A new Li-Polymer pack has a different internal resistance curve than a degraded OEM cell, so the BMS may flag an error or display an incorrect state-of-charge on the first few cycles. This is not a fault with the replacement cell — it is the BMS recalibrating against new chemistry data. Run one complete charge-discharge cycle before clinical use to let the BMS establish an accurate baseline. After that first cycle, charge indicators and low-battery thresholds will read correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMS-2007 fails to power on after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge during storage. If voltage drops below approximately 6.0V, the MS-2007 BMS enters a deep-discharge lockout and will not pass power to the device even when connected to the charger. Place the battery on charge and leave it connected for a minimum of two hours before attempting to power the device on — the charge IC applies a low-current pre-charge phase to recover cells in this state. Once voltage climbs above the BMS recovery threshold (typically 6.8–7.0V on this platform), normal charging resumes and the device will boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381464039514,"sku":"BWCS-SHC102MD-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381464072282,"sku":"BWCS-SHC102MD-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381464105050,"sku":"BWCS-SHC102MD-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHC102MD-1.webp?v=1778901015","url":"https:\/\/batteryweb.com\/products\/schiller-cardiovit-ms-2007-replacement-battery-74v-4200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
