It fits both the SE-3 and SE3 unit variants. Capacity figure is taken directly from product data at 74.88Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSE-3 and SE3 platform fit:\u003c\/strong\u003e\n    Both unit designations run the same 14.4V power rail and share the same HYLB-231 connector pinout and BMS handshake protocol. One SKU covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the SE-3 charge controller and confirmed the BMS negotiated charge termination correctly. The protection circuit tripped at the expected low-voltage cutoff under a simulated monitoring load across ECG, SpO2, and NIBP channels running simultaneously.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After fitting this battery, let the SE-3 complete its full power-on self-test without interrupting it. The device runs a BMS verification step at boot. Cutting power during that sequence flags a battery fault that persists until the next clean reboot — this is not a cell defect.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SE-3 may not complete its boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SE-3 runs a startup self-test that includes a BMS state-of-charge check. A new cell that has not completed its first full charge-discharge cycle may report a state-of-charge value outside the device's expected window. The monitor interprets this as a battery fault and halts the boot sequence. Running one complete charge cycle before clinical use resolves this — the BMS recalibrates its capacity register and passes the threshold on the next boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the SE-3 charge IC applies a conservative current limit to an unrecognised cell, which extends the absorption phase and can leave the indicator sitting at 95–98% for longer than expected. This is the charge controller being cautious, not a fault with the cell. Do not remove the battery during this phase — allow the cycle to terminate naturally. After one full cycle, the charge IC registers the cell's actual capacity and subsequent charges complete normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381507686490,"sku":"BWCS-EDS300MD-1","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381507719258,"sku":"BWCS-EDS300MD-2","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381507752026,"sku":"BWCS-EDS300MD-3","price":116.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EDS300MD-1.webp?v=1778901305","url":"https:\/\/batteryweb.com\/products\/edan-se-3-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
