It holds 17000mAh (183.6Wh) and sits on the robot controller board, maintaining SRAM program memory and the real-time clock whenever mains power is cut. Without a functional cell, a power interruption wipes the robot's active program and job queue.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIRB 2600 and multi-generation controller fit:\u003c\/strong\u003e\n    These ABB robot controllers share the same 10.8V backup rail, connector pinout, and three-cell Li-SOCl2 format across M2000A and M2004 generations — the battery interfaces directly with the controller's memory retention circuit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We measured open-circuit voltage at dispatch and confirmed the cell holds stable voltage under the controller's low-current float draw. The BMS showed no anomalous self-discharge events across the test cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap protocol for ABB robot controllers:\u003c\/strong\u003e\n    Always replace this battery with the controller powered on and in RUN mode. Removing the cell while the controller is off will drain SRAM instantly, erasing the loaded program. If a cold swap occurred, reconnect power and reload the program from your programming device before attempting any robot operation.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the IRB 2600 controller loses its program after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IRB 2600's controller board uses SRAM for active program storage, and SRAM is volatile — it requires continuous voltage to retain data. The backup battery is the sole power source for that memory rail when mains power is absent. Pull the cell with the cabinet off and the SRAM collapses to zero within seconds, taking all loaded tasks, module parameters, and system settings with it. A full program reload from RobotStudio or the teach pendant backup file is the only recovery path.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNew battery installed but the controller still shows a battery alarm\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eABB robot controllers do not auto-clear battery fault flags after a physical cell replacement. The alarm persists in the event log until it is manually acknowledged in RobotStudio or cleared via the FlexPendant under Controller — Event Log — Battery. Additionally, a freshly shipped Li-SOCl2 cell may read slightly below rated voltage for the first few hours; the controller's float charge brings it up to full within that window. Confirm the cell is seated and the connector is fully latched, then clear the alarm manually — do not assume a persistent flag means the new battery is faulty.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415974281306,"sku":"BWCS-ARB260SL-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415974314074,"sku":"BWCS-ARB260SL-2","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415974346842,"sku":"BWCS-ARB260SL-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ARB260SL-1.webp?v=1779758774","url":"https:\/\/batteryweb.com\/products\/abb-irb-2600-m2004-replacement-battery-108v-17000mah-li-socl2","provider":"BatteryWeb","version":"1.0","type":"link"}
