Product Description
Reliable Memory Backup for Your Industrial Equipment
Your programmable logic controller (PLC) is the brain of your operation, but that brain relies on a small battery to keep its memory intact during power outages. When that battery fails, you risk losing critical programming and facing expensive downtime. This high-quality 3.6V Lithium replacement battery is designed to provide the steady, long-term power your Omron system needs to stay protected and ready to run.
Built for Longevity and Performance
In an industrial environment, you need components you can install and forget about. This battery is engineered with a very low self-discharge rate, giving it an impressive 10-year shelf life. Whether it’s sitting in your spare parts bin or installed in your controller, you can trust it to be ready when called upon. Benefits of this high-grade lithium cell include:
- Wide Temperature Range: Operates reliably in extreme conditions from -60° to +85°C (-76° to 185°F).
- Stable Power: Provides a consistent 3.6V output to ensure your data remains safe without fluctuations.
- Quality Construction: Assembled right here in the USA to ensure the highest standards of reliability.
Versatile Compatibility
This single-cell lithium battery is a versatile power solution for a massive range of Omron equipment. It features the correct wire lead connector for a "plug-and-play" replacement, so you don't have to worry about complicated wiring or soldering. It is the standard backup choice for the C20, C120, C500, CQM1, and CV series controllers, among many others.
Frequently Asked Questions
How often should I replace my PLC battery?
Most manufacturers recommend replacing your PLC backup battery every 2 to 3 years as part of a preventative maintenance schedule. Waiting until the "Battery Low" light comes on can sometimes be too late to save your program if a power outage occurs.
What happens if my PLC battery dies?
If the battery fails while the power is off, the controller may lose its internal memory, including your logic programs and settings. Replacing the battery while the PLC is powered on usually prevents this data loss, but always check your specific system manual first.
Is this battery ready to use out of the box?
Yes. This battery arrives fully charged and is assembled in the USA with the necessary wire leads and connector already attached. It is a direct replacement for the original Omron battery and requires no modification to fit your controller.

Customer Reviews
Battery worked in to my Omron Sysmac C40K PLC. Only issue is it's a little too long to fit into the mount inside the PLC, but it still holds it.
