These are portable ECG machines used in clinical and diagnostic settings. Voltage and capacity match OEM specifications — no firmware flags or charge-cycle errors on installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAT102+ and MS-2015 series compatibility:\u003c\/strong\u003e\n    These four models share the same 7.4V battery rail, connector pinout, and BMS handshake protocol. One pack covers all four variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the AT102+ platform. The BMS accepted the pack on first insertion, completed its initialisation sequence, and reported state-of-charge accurately within the first full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the Cardiovit to complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup — cutting power during this sequence triggers a persistent false battery fault that does not clear until the next clean 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 Cardiovit AT102+ reports a battery fault after a confirmed successful swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe AT102+ BMS stores chemistry calibration data from the previous cell. A new pack with a different charge history causes the BMS to flag a mismatch on first boot. This is not a fault with the replacement battery — it is the BMS resetting its internal model. Run one complete charge-discharge cycle and the calibration data overwrites cleanly. The fault indicator clears without any manual reset.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on the first charge after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Cardiovit's charge IC applies a conservative current limit when it detects a cell with no prior charge history. This causes the indicator to plateau — typically between 85% and 95% — before the cycle completes. The cell is not defective and the charge IC has not failed. Let the device charge uninterrupted until it terminates automatically. After one full cycle, the charge IC recalibrates and subsequent charges reach 100% correctly. If the indicator still stalls after three full cycles, check the dock contacts for oxidation and clean with isopropyl alcohol.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381374255194,"sku":"BWCS-SHA102MD-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381374287962,"sku":"BWCS-SHA102MD-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381374320730,"sku":"BWCS-SHA102MD-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHA102MD-1.webp?v=1778900450","url":"https:\/\/batteryweb.com\/products\/schiller-cardiovit-at102-replacement-battery-74v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
