Low-voltage monitoring circuits on the controller continuously query the battery potential, initiating firmware status warnings to backplane bus communication routines before voltage drops below the threshold for memory corruption. This guarantees zero impact on controller program retention or network communication readiness upon chassis power restoration.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Which Allen-Bradley controller hardware series requires the 1756-BA1 battery assembly?\u003c\/p\u003e\n\u003cp\u003eA: The 1756-BA1 is engineered specifically for Series A ControlLogix processors (including 1756-L61, 1756-L62, 1756-L63, 1756-L55M, 1756-L60M03SE) and compatible FlexLogix controllers.\u003c\/p\u003e\n\u003cp\u003eQ: What are the primary electrical output ratings of this lithium assembly?\u003c\/p\u003e\n\u003cp\u003eA: The battery cell outputs a nominal continuous rating of 3 VDC with an integrated charge storage capacity of 1800 mAh.\u003c\/p\u003e\n\u003cp\u003eQ: Will volatile controller memory be cleared if the battery is removed while the chassis is powered?\u003c\/p\u003e\n\u003cp\u003eA: No, if backplane system power to the chassis remains active during replacement, backplane current powers the memory circuits, allowing live battery replacement without losing user program code or clock data.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003ePerform grounding steps to prevent electrostatic discharge (ESD) before handling internal processor components. Access the internal controller panel by opening the front housing door on the host module.\u003c\/p\u003e\n\u003cp\u003eDisconnect the wire connector from the battery header and release the retaining clip securing the depleted battery cell. Insert the new 1756-BA1 unit into the holder and firmly seat the wire plug into the dedicated board connector. Verify that the BAT fault light on the front processor display clears when the module operates on backplane power. Handle and recycle depleted 3V lithium power cells in accordance with local environmental regulations governing hazardous waste disposal.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":48791557767358,"sku":"1756-BA1","price":96.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/1756-BA1_5a3b1331-c7f4-4cc3-9e67-de70e043881d.png?v=1787818888","url":"https:\/\/www.autooiltech.com\/products\/allen-bradley-1756-ba1-controllogix-lithium-battery-assembly","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
