Allen-Bradley 1771-BA PLC-5 Battery 1.5V

Allen-Bradley 1771-BA Backup Battery for PLC Controllers

Product Introduction 1771-BA

The Allen-Bradley 1771-BA battery serves as a vital backup power source for legacy PLC systems. Specifically, it supports PLC-2/20 and PLC-2/30 controllers. This standard D-cell battery ensures that your controller memory remains intact during power interruptions. Its alkaline chemistry delivers stable and reliable performance. Each controller typically requires two of these batteries for proper redundancy. Consequently, this setup protects your automation system from unexpected data loss.

Key Technical Specifications 1771-BA

This 1771-BA battery provides a nominal voltage of 1.5 volts. It offers a substantial capacity of 17,000 mAh. The battery uses button-top terminals for straightforward installation. Its alkaline chemical composition guarantees a consistent power output. Furthermore, this battery is non-rechargeable and designed for single-use applications. You should replace it periodically to ensure uninterrupted controller operation. Each PLC-2/20 and PLC-2/30 controller uses two 1771-BA batteries simultaneously.

Battery Backup Duration 1771-BA

The backup time depends largely on the ambient temperature. At 60 degrees Celsius, this battery provides approximately 6 months of backup power. Meanwhile, at 45 degrees Celsius, it extends its service life to about 12 months. These figures assume normal operating conditions. Therefore, you should monitor the temperature of your control cabinet. Cooler environments significantly prolong the effective life of the 1771-BA battery.

Application and Usage

This battery is exclusively designed for industrial automation applications. It is a critical component for PLC-2/20 and PLC-2/30 systems. These controllers rely on the 1771-BA to preserve program memory and retain critical data. Without this battery, a power failure could result in lost configurations. Consequently, regular replacement is a standard maintenance practice. This ensures that your legacy PLC systems remain operational and reliable.

Installation and Replacement

Installing the 1771-BA battery is a simple process. First, power down the controller to avoid any electrical issues. Then, locate the battery compartment on the PLC unit. Insert two fresh 1771-BA batteries, ensuring correct polarity. The button-top terminals make proper alignment easy. Finally, secure the compartment and restore power to the system. Always replace both batteries at the same time for optimal performance.

Important Safety Considerations

This battery is not rechargeable. Attempting to recharge it may cause leakage or rupture. Additionally, you should never mix old and new batteries in the same controller. Always dispose of used batteries according to local regulations. Proper handling ensures both safety and reliable operation. Furthermore, store spare 1771-BA batteries in a cool, dry location. This practice preserves their capacity until installation.
