It runs at 14.8V with a 1800mAh (26.64Wh) capacity. The Li-ion cell format matches the OEM battery bay without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGE CardioServ platform fit:\u003c\/strong\u003e\n    The CardioServ uses a 14.8V Li-ion rail to power its acquisition module, display, and thermal print mechanism simultaneously. This cell configuration meets that combined load without triggering the BMS undervoltage cutoff during peak draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through a full charge cycle and monitored BMS communication with the host device. The protection circuit balanced correctly across all four cells, and the charge IC accepted the pack without a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the CardioServ to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window stores a false battery fault that persists 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\"\u003eCardioServ not completing boot sequence on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe CardioServ runs a multi-stage startup check that includes a battery state-of-charge handshake. A new cell that has partially self-discharged in storage may report a state-of-charge value below the device's boot threshold, causing the sequence to stall. This is not a faulty battery — it is the BMS reporting accurately on a depleted cell. Charge the battery fully before the first boot, then power on and allow the sequence to complete without interruption. The boot threshold on this platform sits around 12.5V resting voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge cycle, the CardioServ's charge IC applies a conservative current limit to an uncharacterised cell. This causes the charge cycle to terminate early, typically displaying 95–98% rather than full. This is the IC's built-in conditioning behaviour, not a capacity defect. Run one complete charge-to-discharge-to-charge cycle, and the charge controller recalibrates its cutoff voltage to the cell's actual full-charge point of 16.8V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381505818714,"sku":"BWCS-ECG980MD-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381505851482,"sku":"BWCS-ECG980MD-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381505884250,"sku":"BWCS-ECG980MD-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ECG980MD-1.webp?v=1778901305","url":"https:\/\/batteryweb.com\/products\/raytop-lbp144-replacement-battery-148v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
