Mitsubishi PLC Battery Replacement

Reliable Mitsubishi PLC battery for industrial memory backup

A Mitsubishi PLC battery is a small but critical component in automation systems. It supports the controller memory when the power is switched off, helping to preserve programs, parameters, clock data and machine settings. In this category you can find a replacement battery for Mitsubishi Q6BAT, based on the CR17335SE lithium cell specification, with 3V voltage and 1800 mAh capacity.

Choosing the correct PLC backup battery helps reduce downtime, avoid unnecessary reprogramming and support stable operation of production equipment. Whether you maintain a single Mitsubishi controller or service multiple industrial panels, keeping a suitable spare battery available is a practical step for preventive maintenance.

When should a Mitsubishi PLC battery be replaced?

PLC backup batteries are consumable parts. Their service life depends on operating temperature, storage conditions, controller load and the age of the installed cell. Many maintenance teams replace them preventively during scheduled service rather than waiting for a low battery warning.

• Low battery alarm: the controller or HMI may display a warning that the backup battery voltage is low.
• Planned maintenance: replacement at regular intervals helps avoid unexpected stops.
• Long storage periods: machines kept without power may rely heavily on the backup battery.
• Commissioning used equipment: replacing the PLC battery is recommended when the battery age is unknown.
