The Omron 3G2A9-BAT08 is a dedicated PLC memory backup battery designed for Omron PLC systems and industrial automation controllers. This battery assembly commonly uses the Maxell ER17/33 3.6V lithium cell and is specifically engineered to maintain SRAM memory, PLC programs, machine parameters, and operational data when the main system power is disconnected.
The battery features a 3.6V lithium thionyl chloride (Li-SOCl2) cell, known for its high energy density, low self-discharge rate, and long service life in industrial standby applications. Its factory-fitted connector and cable assembly allow direct installation into compatible Omron PLC units without modification.
The 3G2A9-BAT08 is widely used in Omron C500 series PLCs, industrial CNC systems, factory automation equipment, process control systems, and industrial machinery where continuous memory retention is critical during power failures or maintenance shutdowns.
Designed for industrial environments, the battery provides stable voltage output and reliable long-term backup performance. The compact battery pack construction ensures secure installation inside PLC control cabinets and automation systems.
