Professional FAQ

• What is the primary function of the MR-J3BAT in a servo system?

This battery preserves critical data in the servo amplifier's memory. It keeps parameters, positional data, and alarm history safe during a power outage or when the main drive is disconnected.

• How often should I typically replace this battery?

We recommend proactive replacement every 2-3 years under normal conditions. Always replace it immediately if the drive displays a low battery alarm to prevent data loss.

• Can I use rechargeable batteries as a substitute?

No, you should not. The MR-J3BAT is a non-rechargeable lithium cell with specific discharge characteristics. Using an incorrect battery type can damage the drive or cause data corruption.

• Is this battery compatible with older Mitsubishi drive series?

Yes, it serves as a direct OEM replacement for many models. Common compatible part numbers include Maxell ER6VC119A/ER6VC119B and Mitsubishi part number 160224.

• What's the best practice for installing this battery?

Always install the new battery while the main drive unit is powered ON. This prevents any memory loss during the swap. Ensure the connector is firmly seated.
