Features

  • Designed for Series B 1756-L61, 1756-L62, 1756-L63, 1756-L64, and 1756-L65 controllers.
  • Compatible with GuardLogix 1756-L61S, 1756-L62S, and 1756-L63S safety controllers.
  • Nominal output of 3V DC with a 1200 mAh capacity.
  • Equipped with pre-attached wire leads and a secure connector for simple installation.
  • Long-term backup capability with a shelf life of up to 10 years at 25 degC.

Applications

This battery assembly is essential for maintaining operational continuity in industrial environments where PLC memory retention is critical, including:

  • Factory automation and control panel logic protection.
  • Continuous process industries such as chemical, refining, and food processing.
  • CNC machining for safeguarding axis positions and cutting routines.
  • Data logging systems requiring preservation of alarm history and runtime metrics.

Installation Guidelines

  • Chassis Power: Keep the chassis backplane power turned ON during a live battery swap to ensure the controller's memory remains powered by the backplane.
  • Safety: Do not connect or disconnect the battery in hazardous locations. Breaking connections under power can cause an electrical arc.
  • ESD Precautions: Use an approved, grounded wrist strap and avoid touching circuit boards or exposed pins within the chassis.
  • Backup: Always verify that a current copy of the PLC program is saved to an offline storage medium before performing maintenance.

FAQ

Which controllers are compatible with the 1756-BA2?

This battery is designed exclusively for Series B ControlLogix 5560 (1756-L6x) controllers. It is not compatible with Series A controllers, which typically require the 1756-BA1 assembly.

Can I use a 1756-BA1 instead of a 1756-BA2?

No. These batteries are not interchangeable due to different connector types and specific current management requirements of the Series B processors. Using an incorrect battery can lead to equipment failure.

Is the 1756-BA2 battery rechargeable?

No. This is a non-rechargeable lithium battery. Attempting to recharge this unit creates a severe risk of fire, explosion, or thermal runaway.
