Product Summary
The Allen-Bradley 1747-BA is a critical replacement battery for the SLC 500 platform. This genuine 3 Volt lithium cell preserves processor RAM data during power loss. Engineers rely on this module to prevent costly program corruption across multiple processor models.
Why You Need the Genuine 1747-BA for Your SLC System
Procuring the correct 1747-BA ensures your SLC 500 processor maintains program integrity. This lithium battery delivers reliable power for RAM backup. It supports the SLC 5/02, 5/03, 5/04, and 5/05 models for approximately two years.
Each unit contains exactly 0.23 grams of lithium. This composition enables safe shipment of up to two batteries within the United States. You must follow Class 9 Dangerous Goods regulations for international transport always.

The battery operates within a temperature range of 0-60 degrees Celsius. Store it in a cool and dry environment between 20-25°C for maximum shelf life. Maintain a relative humidity of 40-60 percent in your storage area at all times.
Step-by-Step User and Installation Guide
Begin by powering down your SLC 500 processor completely. Locate the battery compartment on the front of your processor module. Remove the old battery carefully without touching any internal circuit boards.
Connect the new 1747-BA using its 6-Pin Phoenix connector. Ensure the cable, which is Belden 9463, sits securely in the socket. Check that the battery LED on the processor turns off after installation.
Never short-circuit, disassemble, or heat this battery during installation. Avoid placing the 1747-BA on any metal objects or antistatic materials. Keep the unit away from water, rain, snow, or frost completely.

For systems using multiple batteries, replace all cells simultaneously with new ones. Never mix old and new batteries within the same system. The processor will alert you via its battery LED when voltage runs low.

Expert Technical Evaluation and Performance Review
This 3 Volt battery draws a backplane current of 375 milliamps at 5 Volts DC. It provides approximately five years of backup for the 1747-L511 processor model. The 1747-L514 model gets roughly two years of backup power from the same unit.
The dimensions of the 1747-BA are 5.72 by 1.37 by 5.15 inches. It weighs 0.37 pounds or 168 grams. This compact form factor fits perfectly into existing SLC 500 chassis without any modifications.
You must regularly monitor the temperature and humidity of your storage area. Lithium metal cells require careful handling to avoid dangerous conditions. Do not pile or blend batteries together during storage to prevent short circuits.
The battery LED on your processor provides a clear low voltage warning. Replace the 1747-BA promptly when you see this indicator activate. Waiting too long risks losing your processor’s volatile memory data.
This unit is not rechargeable but is easily replaceable in the field. Always source genuine Allen-Bradley parts for critical automation systems. Aftermarket batteries may not meet the same safety or performance standards.
