These are portable clinical ECG machines used for cardiac monitoring and diagnostic testing. Cross-references OEM part numbers 4.350027c, 02175, 506161, and 3.920509.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAT10+ \/ AT10 Plus \/ AT110 platform fit:\u003c\/strong\u003e\n    These three models share the same 21.6V battery architecture, connector pinout, and BMS handshake protocol — the same cell works across all three without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on the AT10+ platform. The BMS completed cell recognition on the first cycle, and the device passed its internal power-on self-test without fault flags on subsequent boots.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation startup protocol:\u003c\/strong\u003e\n    After fitting this battery, let the AT10+ complete its full power-on self-test cycle without interruption. The device runs a BMS verification routine at startup — cutting power during this sequence triggers a false battery fault that will persist 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\"\u003eAT10+ not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AT10+ runs a multi-stage BMS handshake during boot that checks cell voltage, internal resistance, and chemistry signature against stored OEM parameters. A new Li-ion cell that hasn't completed its first full charge-discharge cycle can present an internal resistance value outside the expected window, causing the device to stall mid-boot. This isn't a faulty battery — it's the BMS applying a conservative threshold against an unconditioned cell. Run one complete charge to full, then discharge under normal clinical load, and the boot sequence will complete normally on the next power-on.\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 cycle, the AT10+'s charge IC applies a conservative current limit to a new cell while it maps cell capacity. This causes the charge progress indicator to slow significantly or appear to stall between 90–95%. The cell is still accepting charge — the IC is completing a trickle-top phase to verify the cell holds voltage under reduced current. Let the charge cycle finish without interrupting it; the indicator will reach 100% and the BMS will register a full baseline. Disconnect only after the device confirms charge complete, not based on estimated time.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381465612378,"sku":"BWCS-SHC100MD-1","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381465645146,"sku":"BWCS-SHC100MD-2","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381465677914,"sku":"BWCS-SHC100MD-3","price":109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHC100MD-1.webp?v=1778901015","url":"https:\/\/batteryweb.com\/products\/schiller-ekg-at10-replacement-battery-216v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
