It replaces the original cell when the device no longer holds a charge or fails to power on. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eET280 platform fit:\u003c\/strong\u003e\n    The ET280 runs a single-cell 3.7V Li-ion architecture. The BMS in this unit monitors cell voltage and temperature, and the connector pinout matches the OEM housing — no adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the ET280 platform. The BMS reported correct cell state, and the device completed a full boot sequence without triggering low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRAM power and data sync before swap:\u003c\/strong\u003e\n    The ET280 stores open application state and unsaved data in volatile RAM powered directly by the main battery. Before removing the old cell, perform a full data sync to your host computer — pulling the battery without syncing will wipe anything not written to flash storage.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eET280 not booting after new battery installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at partial charge — typically 40–60% — and the ET280 boot sequence requires a minimum threshold voltage to initialise the operating system. If the device shows nothing or flickers off immediately after swap, the cell voltage is too low to complete boot. Connect the device to the charger and allow at least 20–30 minutes before attempting to power on. The battery must reach approximately 3.6V before the boot sequence will run to completion.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery life shorter than expected during active warehouse scanning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ET280's barcode scanner LED and wireless radio draw significantly more current than the standby baseline. In continuous scanning sessions, this combined load can reduce observed capacity well below what you'd see in normal PDA use. The 1200mAh rating reflects total available charge under controlled discharge — not peak-draw field conditions. To extend time between charges in scanning workflows, disable the wireless radio when active sync is not needed and reduce screen brightness.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415944134746,"sku":"BWCS-ET280SL-1","price":27.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43415944167514,"sku":"BWCS-ET280SL-2","price":31.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43415944200282,"sku":"BWCS-ET280SL-3","price":34.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ET280SL-big.webp?v=1779758396","url":"https:\/\/batteryweb.com\/products\/lenovo-et280-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
