The AR2100 is used in clinical and ambulatory cardiac diagnostic settings where a stable, uninterrupted power supply is critical during patient monitoring. This battery slots into the AR2100's internal bay and interfaces directly with the device's onboard BMS.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAR2100 ECG platform fit:\u003c\/strong\u003e\n    The AR2100 uses a 12V sealed lead acid cell because its acquisition circuitry and signal processing board run from a regulated rail derived from that voltage. Swapping chemistry type or voltage — even by a small margin — will cause the charge IC to misread state-of-charge and trigger erroneous low-battery faults.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the AR2100's charge cycle and confirmed the BMS accepted the new battery without flagging a chemistry mismatch. The charge controller reached float stage cleanly and the self-test completed without interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install startup protocol:\u003c\/strong\u003e\n    After fitting this battery, let the AR2100 complete its full power-on self-test without powering it off mid-sequence. The BMS runs a verification pass at startup — cutting power during this window causes a false battery fault that sticks until the device completes a clean reboot from a full charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the AR2100 reports low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSealed lead acid cells shipped from storage carry a partial state of charge. The AR2100's BMS compares resting voltage against an OEM-calibrated threshold, and a new cell that hasn't completed a full charge-discharge cycle often sits just below that threshold. The device reads this as a depleted battery even when the charger has indicated full. One complete charge-discharge cycle recalibrates the BMS's reference point and clears the false alarm. Do not use the AR2100 clinically until this cycle is complete and the device passes its self-test.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAR2100 shutting off unexpectedly during ECG acquisition\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring the first 10 charge cycles, a new sealed lead acid cell delivers slightly lower peak current than a fully conditioned cell. The AR2100's load profile during active ECG acquisition stresses the cell harder than standby mode, and the BMS may trigger a low-voltage cutoff under that load even when resting voltage looked acceptable. This is not a fault with the battery — it resolves as the cell conditions through normal use cycles. If cutoffs persist beyond 10 cycles, check resting voltage with a multimeter: a healthy 12V SLA cell should read at least 12.6V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381384282202,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381384314970,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381384347738,"sku":"BWCS-SHT160MD-3","price":415.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHT160MD-1.webp?v=1778900511","url":"https:\/\/batteryweb.com\/products\/cardioline-ar2100-ecg-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
