It slots into the LUCON to maintain device power during clinical use when the primary battery is depleted or removed for charging. No OEM part number is published for this battery; fit is confirmed by voltage, form factor, and connector match to the LUCON platform.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLUCON platform fit:\u003c\/strong\u003e\n    The LUCON runs a single 11.1V three-cell Li-ion pack. Voltage rail, connector orientation, and BMS handshake are all matched to this configuration — the device will reject a pack that reports an incompatible cell count or voltage signature on startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the LUCON's startup self-test sequence. The BMS exchanged state-of-charge data correctly, the device passed its power-on verification, and no battery fault codes were logged across multiple boot cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on medical devices:\u003c\/strong\u003e\n    After installing this battery, let the LUCON complete its power-on self-test without interruption. The BMS runs a chemistry verification routine at boot — interrupting it during the first cycle can set a false battery fault that persists until the next full reboot. Allow one complete charge-discharge cycle before clinical deployment.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the LUCON alarms low battery with a freshly charged replacement installed\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe LUCON's BMS compares incoming cell data against a stored threshold profile calibrated to the original OEM chemistry. A new replacement cell has not yet completed the learn cycle that lets the BMS map its actual charge curve. Until that cycle runs, the BMS may read state-of-charge conservatively and trigger a low-battery alarm even on a full pack. One complete charge-discharge cycle — starting from a full charge down to the device's automatic cutoff — trains the BMS to read the new cell accurately. After that cycle, the alarm clears and charge reporting stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLUCON will not power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If this battery has been stored for several months, its resting voltage may have dropped below the LUCON's BMS recovery threshold — typically around 9V for an 11.1V three-cell pack — and the device will not initialise. Connect the battery to a compatible Li-ion charger directly before installing it in the device. Once the cell voltage is restored above the recovery floor, the LUCON will recognise the pack and complete its boot sequence normally. Verify resting voltage is at least 10.5V before attempting device power-on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381398175834,"sku":"BWCS-CKP121MD-1","price":146.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381398208602,"sku":"BWCS-CKP121MD-2","price":174.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381398241370,"sku":"BWCS-CKP121MD-3","price":195.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CKP121MD-1.webp?v=1778900536","url":"https:\/\/batteryweb.com\/products\/mediana-lucon-replacement-battery-111v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
