Description

The 1747-BA is a non-rechargeable lithium primary battery from Rockwell Automation, specifically engineered for memory backup in SLC 500 and MicroLogix 1500 programmable controllers. The 1747-BA preserves critical user program data, tag values, and controller configurations when system power is interrupted or during battery replacement intervals. With 0.23 grams of lithium metal and 950 mAh capacity, the 1747-BA provides reliable data retention across the full –20°C to +60°C operating range. The 1747-BA plugs directly into the processor PCB via a dedicated connector, ensuring positive retention and simple field replacement without soldering or specialized tools. The 1747-BA ships from the factory as a standalone component, not included with processors that feature capacitor backup.

Applications

Memory Retention in SLC 500 Systems – Preserves application programs, ladder logic, and tag databases in SLC 5/01, 5/02, 5/03, 5/04, and 5/05 processors during power outages or scheduled maintenance shutdowns
Data Preservation in Fixed Controllers – Provides program backup for SLC 500 fixed hardware style controllers where capacitor backup duration (5–30 days) is insufficient for expected downtime scenarios
MicroLogix 1500 Program Backup – Replaces depleted batteries in MicroLogix 1500 controller applications requiring long-term program retention without sustained system power
Periodic Preventive Maintenance – Supports scheduled replacement of aging batteries to prevent unexpected program loss in critical automation cells, conveyor systems, and material handling equipment
Legacy System Sustenance – Enables continued operation of installed SLC 500 systems, eliminating the need for immediate migration to newer platforms while maintaining program integrity across power cycles
Replacement Inventory – Maintains spare stock for rapid field replacement during battery-low fault conditions indicated by processor status LEDs

Features

Extended Memory Backup – Provides continuous memory support for processor RAM, retaining programs and data during power-down conditions
Simple Plug-In Installation – Connectorized design enables tool-free battery replacement; no soldering or specialized tools required
Positive Mechanical Retention – Retaining clips hold battery securely in place within the processor housing, preventing disconnection during shock or vibration
Wide Operating Temperature – Functions reliably across –20°C to +60°C ambient conditions
Capacitor Backup Interlock – SLC 5/03, 5/04, and 5/05 processors include a capacitor providing at least 30 minutes of backup during battery replacement, preventing data loss during exchange
Long Shelf Life – 10-year maximum storage duration when properly stored in original containers at 20–25°C and 40–60% RH
Hazardous Location Compatible – Supports Class I Division 2 installations when replaced in non-hazardous areas per applicable safety guidelines
Universal Waste Disposal – Can be disposed of as universal waste in most US states, simplifying end-of-life management

Competitive Advantage

Specifically Designed for SLC 500 – Unlike general-purpose batteries, the 1747-BA is form-fitted and connectorized for Allen-Bradley processors, ensuring reliable physical and electrical compatibility without adapter cables or terminal block modifications.
Capacitor Backup Window – When replacing the battery in SLC 5/03, 5/04, and 5/05 processors, an internal capacitor provides at least 30 minutes of backup power, giving operators time to complete the exchange without program loss—a feature not available on many competitive PLC memory retention solutions.
Long Replacement Interval – The 1747-BA typically provides 3–5 years of service life in normal operating conditions, reducing the frequency of planned maintenance interventions and minimizing plant downtime.
Global Transport Regulatory Support – Includes DOT-E7052 exemption for commercial shipment, with clearly defined packaging and labeling requirements that simplify logistics management for end-users and distributors.
Standardized Disposal Pathways – Universal waste classification in most US states eliminates the need for specialized hazardous waste handling, reducing end-of-life management costs and complexity.
Rockwell Quality Assurance – Manufactured to Allen-Bradley specification by qualified suppliers (Sanyo or Tadiran), ensuring consistent cell performance and reliability across production batches.

FAQ

Q1: What is the battery life expectancy of the 1747-BA?

A1: Under normal operating conditions at 20–25°C ambient temperature, the 1747-BA typically provides 3–5 years of service life. Actual duration depends on processor type, memory usage, ambient temperature, and the number of power-off periods experienced by the controller.

Q2: Can the 1747-BA be recharged?

A2: No. The 1747-BA is a primary (non-rechargeable) lithium cell. Attempting to recharge it may cause overheating, rupture, or explosion, resulting in personal injury or equipment damage. Dispose of depleted batteries according to applicable regulations and use only new replacement units.

Q3: Can the 1747-BA be replaced while the processor is powered on?

A3: For SLC 5/01, 5/02, and fixed controllers, the battery can be replaced with processor power applied. For SLC 5/03, 5/04, and 5/05, it is recommended to remove processor power and extract the processor from the chassis before replacement to prevent static damage. In all cases, the replacement area must be non-hazardous per Class I Division 2 requirements.

Q4: What happens if the 1747-BA is disconnected for too long?

A4: In processors with capacitor backup (SLC 5/03, 5/04, 5/05), you have approximately 30 minutes to complete the battery replacement before data is lost. Older processors and fixed controllers do not have this capacitor backup; disconnecting the battery without applying external power may immediately corrupt memory contents.

Q5: How should depleted 1747-BA batteries be disposed of?

A5: Depleted 1747-BA batteries should never be incinerated or discarded in general waste. In most US states, they can be disposed of as universal waste through authorized battery recyclers. Alternatively, they may be shipped as hazardous waste. Contact your local EPA office or consult state and local regulations for specific requirements.
