CJ1W-BAT01, Omron PLC Lithium Backup Battery, 3V replacement battery for CJ1, CS1, and NJ Series controllers

The CJ1W-BAT01 is a high-quality, long-life lithium replacement battery designed specifically for industrial automation systems. This 3V primary battery serves as the critical memory backup for a wide range of programmable logic controllers (PLCs), including the Omron CJ1, CS1, and NJ Series. It ensures that your system’s volatile memory—including user programs, system settings, and real-time clock data—is preserved during power outages or machine shutdowns. Pre-fitted with a dedicated polarized lead wire and a secure plug-in connector, it allows for a fast, tool-free replacement that minimizes system downtime.

Key Features

• Critical Data Retention: Provides reliable 3V backup power to prevent the loss of internal PLC programs and parameter settings during primary power interruptions.
• Broad System Compatibility: Engineered as a direct replacement for various industrial controllers, including the CJ1G/H/M, CS1G/H/D, and NJ Series CPUs.
• Long Shelf Life: Utilizes Lithium Thionyl Chloride technology, offering an exceptionally low self-discharge rate for a service life of up to 5 years (depending on ambient conditions).
• Plug-and-Play Installation: Comes equipped with a pre-terminated, keyed connector and lead wire for a secure, foolproof connection to the PLC battery port.
• Wide Temperature Range: Designed to operate reliably within harsh industrial environments, maintaining stable voltage in both extreme heat and cold.
• Compact Form Factor: Designed to fit perfectly into the dedicated battery compartments of Omron CPUs without obstructing adjacent expansion modules.
