Key Features & Handling Guidelines

The 1747-BA contains 0.23 grams of lithium metal, classifying it as UN Class 9 Dangerous Goods for regulated transport and safety handling. It serves as an essential maintenance component to maintain user logic, memory registers, and real-time clock data when processor primary power is removed. To maintain cell integrity, store the battery in a cool, dry area at 20-25°C. Avoid direct contact with metal surfaces, antistatic conductive materials, moisture, high heat, or mechanical damage during replacement procedures.

Frequently Asked Questions (FAQs)

Q1: How long does the 1747-BA battery last in SLC 500 controllers?
A1: Backup life is approximately 5 years for SLC 5/01 (1747-L511) processors, and approximately 2 years for SLC 5/02, 5/03, 5/04, and 5/05 controllers.

Q2: How do I know when the 1747-BA battery needs replacement?
A2: The red "BAT" LED indicator on the front panel of the SLC processor illuminates when the battery voltage drops below the threshold level.

Q3: Is the Allen-Bradley 1747-BA lithium battery rechargeable?
A3: No, the 1747-BA is a non-rechargeable primary lithium cell and must be replaced with a new unit when depleted.
