Product Overview

The Allen-Bradley 1756-BA1 serves as the primary backup power source for ControlLogix processor volatile memory. This 3.0V DC Lithium battery safeguards critical user programs, tag data, and system configurations during total power interruptions or chassis maintenance. Without a functional battery, a power cycle results in the immediate loss of the controller's internal RAM contents. We supply this product as 100% Brand New and Original in Factory Packing, providing the full chemical shelf life and 12 months of factory warranty for your facility’s protection.

Technical Specifications

The 1756-BA1 features high energy density and stable voltage discharge characteristics to support long-term automation stability.

Engineering Advantages

• Zero-Data-Loss Architecture: The 1756-BA1 sustains the controller's internal SRAM, allowing the PLC to resume operation instantly upon power restoration without requiring a program reload from non-volatile storage.

• Plug-and-Play Maintenance: The battery module features a keyed connector that prevents polarity errors during installation. This design enables rapid field replacement, minimizing the "cabinet-open" time for maintenance personnel.

• Extended Discharge Reliability: With a 1200 mAh capacity, the 1756-BA1 provides consistent voltage levels even in low-temperature environments that typically degrade standard alkaline or inferior lithium cells.

• Integrated Diagnostic Warnings: When paired with ControlLogix processors, the system monitors the battery's voltage health. The CPU triggers a "BATT" LED on the front panel and sets a system bit in the controller tags when the voltage drops below a critical threshold, providing ample lead time for scheduled replacement.

FAQs

Q: Can I replace the 1756-BA1 while the ControlLogix controller is powered off?

A: No. You must replace the battery while the controller has power applied to the chassis. If you remove the 1756-BA1 while the power is off, the controller loses its program and internal data within seconds.

Q: How do I know if this battery fits my specific processor?

A: The 1756-BA1 specifically supports the ControlLogix 1756-L6x and 1756-L7x series processors. Note that newer L8x series controllers utilize Energy Storage Modules (ESM) based on capacitor technology and do not require this lithium battery.

Q: What is the shelf life of an uninstalled 1756-BA1 battery?

A: High-quality lithium cells like the 1756-BA1 maintain their charge for up to 5-10 years in proper storage (-40 to 85 C). However, for maximum reliability in industrial control loops, we recommend installing the battery within 1-2 years of the manufacture date.

Q: Does the "2 Kg" shipping weight represent a single battery?

A: No. A single 1756-BA1 is very light. The 2 Kg shipping weight typically accounts for protective industrial packaging, documentation, and the secure boxing required to meet international lithium battery shipping regulations (IATA/DOT).
