Battery for Omron C20 C20P C20PF - 3.6V

Omron PLC battery for dependable memory backup

An Omron PLC battery is a small component with an important role: it helps preserve program memory, parameters and real-time clock data when the controller is powered down. In this category you can find a compatible 3.6V battery for Omron C20, C20P and C20PF PLC controllers, selected for maintenance teams, automation technicians and industrial users who need a practical replacement for ageing backup batteries.

Replacing the PLC battery on time reduces the risk of unexpected data loss and unnecessary downtime. If your Omron controller displays a battery warning, has been stored for a long period, or is part of preventive maintenance, choosing the correct replacement battery helps keep your automation system ready for operation.

Why choose the correct Omron C20 battery?

PLC systems are often installed in production lines, control cabinets, machines and process equipment where stability matters. The battery is not used for powering the PLC during normal operation; instead, it supports memory retention when mains power is off. For older Omron C series controllers, using a suitable 3.6V replacement is essential for maintaining reliable backup performance.

  • Compatibility: designed for Omron C20, C20P and C20PF controller applications.
  • Voltage: 3.6V, matching the required PLC backup battery specification.
  • Maintenance value: ideal for scheduled service, repairs and spare-part stock.
  • Industrial use: suitable for automation panels, machinery and control systems.

Tip: Before replacing any PLC battery, follow the controller service procedure and make sure the program and settings are backed up where possible.

When should an Omron PLC backup battery be replaced?

Many industrial batteries are replaced during planned maintenance rather than waiting for a fault. A low battery warning, a long period without replacement, unstable memory retention, or a machine restart after storage can all indicate that it is time to install a new battery. Preventive replacement is usually faster and more cost-effective than recovering lost PLC data after a complete discharge.

For Omron C20, C20P and C20PF controllers, the right battery helps maintain the stored logic and configuration when the equipment is switched off. This is especially important for machines that are stopped overnight, moved between locations, or kept as backup equipment. Keeping a spare Omron PLC battery on hand can help your technical team react quickly when service is needed.
