It supports mobile operation at the bedside or in remote clinical settings where AC power is unavailable. Cross-references include OEM part numbers 5120410-2, 5422172, TWBP42, M2836, and M2836NO.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLogiq E \/ Logiq I \/ Vivid E platform fit:\u003c\/strong\u003e\n    These three portable ultrasound platforms share a common 14.8V battery architecture, connector pinout, and BMS communication protocol — which is why one pack spans all three. The charge controller on each unit expects the same cell chemistry and voltage curve to pass its internal verification check.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and load cycles on a GE Logiq E unit. The BMS handshake completed correctly, the power-on self-test passed without fault codes, and the charge IC accepted the cell without flagging a chemistry mismatch.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After installing this battery, allow the Logiq E to complete its full power-on self-test cycle without interruption. The device runs a BMS verification routine at boot — cutting power during this sequence triggers a persistent battery fault that will not clear until the unit completes a clean, uninterrupted reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGE Logiq E alarming low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Logiq E charge controller calibrates its state-of-charge model against the OEM cell's known capacity curve. A new replacement cell has not yet completed a full charge-discharge cycle, so the BMS lacks a calibrated reference point and flags a conservative low-battery threshold. This is not a fault with the battery — it is the device applying a safety margin against an uncalibrated pack. Run one complete charge from flat to full, then discharge the unit under normal imaging load before returning it to clinical rotation. After that cycle, the state-of-charge readout stabilises and alarms stop firing prematurely.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLogiq E not completing boot sequence after the battery sat unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage, and the GE Logiq E BMS has a minimum recovery threshold — typically around 10.0–10.5V — below which it refuses to initiate the boot sequence as a protection measure. If the pack voltage has dropped below that floor, the device appears completely dead even with the battery installed. Connect the unit to AC mains power first, allow the charge IC to trickle-charge the pack back above the recovery threshold for at least 30 minutes, then attempt to power on. Do not attempt to boot the device on battery alone until the charge indicator shows at least one bar of charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381476491354,"sku":"BWCS-GMP420MD-1","price":324.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381476524122,"sku":"BWCS-GMP420MD-2","price":383.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381476556890,"sku":"BWCS-GMP420MD-3","price":428.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMP420MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/ge-logiq-e-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
