Typically, you should change a PLC battery every 3 to 5 years, though it can vary based on the model and battery type. The battery keeps the real-time clock running and holds memory when the PLC loses power.

Here are a few things to keep in mind:

  1. Manufacturer’s Advice: Always check the manufacturer’s recommendation for your specific PLC, as this will be the most accurate for your setup.
  2. Battery Type: Some PLCs use long-lasting batteries like lithium, while others might need a change sooner, especially if they use rechargeable types.
  3. Usage: If the PLC is frequently turned on and off or exposed to temperature changes, it might require more frequent battery replacements.
  4. Battery Alerts: Many PLCs will give you a heads-up when the battery is running low, which can be really helpful in avoiding unexpected issues.

It’s a good idea to swap out the battery before it dies completely to prevent losing important settings or data!
