Allen-Bradley 1771-BA Standard D-Cell Battery for PLC Backup

Technical Specifications Breakdown

Key parameters for the 1771-BA are listed below for quick reference:

Industry Applications and Cost Impact

In manufacturing plants, the 1771-BA battery supports PLC-2/20 and PLC-2/30 controllers that manage assembly lines, packaging systems, and material handling. A single power outage can halt production for hours if program memory is lost. By providing up to 12 months of backup at 45 degrees Celsius, this battery minimizes downtime costs. Each controller uses two 1771-BA batteries, offering redundancy without significant expense.

Installation and Setup Guidance

Installing the 1771-BA battery is straightforward due to its button-top terminals. Ensure the controller is powered down before replacing batteries. Insert two batteries per controller, observing correct polarity as marked. The non-rechargeable alkaline chemistry means you must replace them when depleted. For optimal cost efficiency, schedule replacements based on your ambient temperature—sooner in hotter environments.

Maintenance and Reliability

Inspect the 1771-BA battery periodically for leakage or corrosion. In typical industrial settings, check every six months. At 60 degrees Celsius, backup time is about 6 months; at 45 degrees Celsius, it extends to 12 months. Regular inspection prevents unexpected failures and avoids costly emergency replacements. Store spare batteries in a cool, dry place to prolong shelf life.

Cost-Effective Backup Power for Critical PLC Systems

Industrial automation downtime can be costly. The Allen-Bradley 1771-BA standard D-cell battery offers a reliable and economical solution for maintaining program memory in PLC-2/20 and PLC-2/30 controllers during power interruptions. With a voltage of 1.5 volts and a capacity of 17,000 mAh, this alkaline battery ensures your systems stay operational, reducing the risk of data loss and production delays.

Selection Guide and Purchasing Advice

When ordering the 1771-BA, verify compatibility with your PLC-2/20 or PLC-2/30 controller. AutoDCSTech offers genuine Allen-Bradley batteries with full traceability.
