It replaces OEM part 58-0114-000 and maintains power to the device during mains outages. Without a healthy backup battery, these clocks lose attendance records, employee enrollments, and current time the moment AC power drops.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eATR240 and ATR360 compatibility:\u003c\/strong\u003e\n    Both models run the same 14.4V battery rail and use the same connector and BMS handshake. One battery covers both clocks — no modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles on the ATR240 platform and confirmed the BMS accepted the cell, balanced correctly, and held stable voltage across the backup load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eData export before swap:\u003c\/strong\u003e\n    Export all employee attendance records and enrollment data before cutting power for the swap. The ATR240 stores this data in battery-backed RAM — full power removal wipes it. The OEM service guide confirms this. Do not skip the export step.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ATR240 loses all employee data after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ATR240 holds attendance records and employee enrollments in battery-backed SRAM. This RAM needs a continuous voltage supply — from either AC power or the backup battery — to retain data. When both sources drop to zero simultaneously, the SRAM loses power and all stored data is erased. Swapping the battery without first exporting data or keeping AC connected during the swap is the most common cause of complete data loss on this platform.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eClock showing wrong time after every power outage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe real-time clock (RTC) on the ATR240 draws from the backup battery during any AC interruption. A battery that has lost capacity may hold enough voltage to show a green indicator but still drop below the RTC's minimum operating threshold under even light load. The result is the clock resetting to a default time — typically 12:00 — after each outage. Replace the battery, allow a full charge cycle, then verify the RTC holds correct time through a simulated 30-second power cut by pulling the AC plug and reconnecting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426140618842,"sku":"BWCS-ART240SL-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426140651610,"sku":"BWCS-ART240SL-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426140684378,"sku":"BWCS-ART240SL-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ART240SL-1.webp?v=1779930363","url":"https:\/\/batteryweb.com\/products\/acroprint-atr240-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
