PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1747-BA is a lithium Battery for the SLC 500 system. This non-rechargeable battery provides RAM backup power for SLC 500 controllers during shutdowns. It provides backup power for approximately five years in 1747-L511 processors. The unit supports memory retention for approximately two years in 1747-L514 processors. It also maintains RAM for approximately two years in SLC 5/02, 5/03, 5/04, and 5/05 processors. A processor battery LED illuminates when battery voltage drops below operational levels.
Each 1747-BA battery contains 0.23 grams of lithium metal. Standard United States shipping rules allow up to two batteries packed together. Storage conditions require temperatures between 20°C and 25°C with 40% to 60% relative humidity. Users must regularly monitor storage temperature and humidity levels. Do not short-circuit, disassemble, puncture, heat, or incinerate this lithium cell. Keep the battery away from water, moisture, conductive surfaces, and antistatic materials.
