Mitsubishi PLC Dedicated Batteries: Reliable Backup Power Solutions for Industrial Automation

In the field of industrial automation, a stable and reliable power supply is the cornerstone of ensuring the continuous operation of production lines. Mitsubishi PLC dedicated batteries, acting as guardians of programs and data, become the last line of defense for industrial control systems in the event of a sudden power outage.

01 The Line of Defense for Industrial Automation Systems: Loyal Guardians of Programs and Data

In the field of industrial control, Mitsubishi PLC systems play a core control role, and backup batteries are key components that ensure these systems maintain normal operation during power outages.

These dedicated batteries typically feature a compact cylindrical or square design with a robust casing, capable of withstanding vibrations and temperature fluctuations in industrial environments.

Unlike ordinary consumer-grade batteries, Mitsubishi PLC dedicated batteries have a special interface design that ensures perfect compatibility with corresponding PLC modules. Holding them in your hand, you can feel their solid workmanship and precise interface design, reflecting the reliability and durability unique to industrial-grade products.

02 Design and Appearance Advantages

Power Solutions Designed for Industrial Environments

Mitsubishi PLC batteries are designed with the specific requirements of industrial environments in mind, achieving a careful balance between portability and performance:

Compact Design: Most Mitsubishi PLC batteries feature a compact design; for example, the LS14500-MER model is only 0.62 inches in diameter, 2.02 inches high, and weighs approximately 0.12 pounds. This small design allows for easy installation in the limited space of various PLC devices.

Industrial-Grade Construction: The battery casing is typically made of high-temperature resistant and impact-resistant materials, protecting the internal cells in harsh industrial environments and ensuring safe and stable operation.

Balance of Portability and Performance: The lightweight design facilitates carrying and installation by technicians without sacrificing battery capacity and performance. For example, the LS14500-MF battery provides a 2600mAh capacity within a compact size, balancing size and battery life requirements.

Anti-Incorrect Design: The battery interface features an oriented design to prevent incorrect installation, allowing for quick and accurate replacement even in low-light industrial environments.

03 Core Performance and User Experience

A Long-Lasting and Reliable Industrial Power Source

The core configuration of Mitsubishi PLC-specific batteries is designed for the sustained and stable power requirements of industrial environments, suitable for providing continuous power to PLC systems under harsh conditions:

Hardware Configuration: Mitsubishi PLC batteries cover a variety of specifications, ranging from 3V to 3.6V, and capacities from 500mAh to 5000mAh, meeting the power consumption requirements of different PLC models. For example, the CR17335SE-MC offers 3V voltage and 1800mAh capacity, while the BR-CCF1TH offers 3V and a higher capacity of 5000mAh.

Performance: Mitsubishi PLC batteries are designed to operate stably over a wide temperature range, adapting to temperature fluctuations in industrial environments. For example, the Q06HCPU has a battery life guarantee of 41,785 hours (approximately 4.77 years) at 50% power-on rate.

Technical Characteristics: Utilizing lithium-ion technology, they feature low self-discharge characteristics, ensuring that PLC programs and data are not lost even during prolonged power outages. Some models, such as the LS14500-MER, are specifically designed for long-term reliability.

Key Experience Component: As a data security component of the PLC system, the battery's performance directly affects whether the equipment can resume normal operation after a power outage. High-quality batteries can prevent production interruptions and data loss due to power problems.

04 Battery Issues and Solutions: Identifying Battery Aging and Replacement Timing

For Mitsubishi PLC users, battery issues directly impact the stability of the production system and data security:

Problem Manifestations: Battery aging typically manifests as PLC battery alarms, program loss after power failure, clock information reset, or the system still indicating a power abnormality even after battery replacement. In servo amplifier systems, battery failure may result in fault codes such as "9F," "9F.1," and "92.3."

Influencing Factors: Temperature fluctuations in industrial environments are a major factor affecting battery life. VRLA (valve-regulated lead-acid) batteries are typically designed for a 10-year lifespan, but their actual service life is often only 3-5 years. Frequent deep discharges and inappropriate float charging also accelerate battery performance degradation.

Solution: Replacing the battery with an original or certified compatible one is the most effective way to restore system reliability. Several direct replacement batteries designed specifically for Mitsubishi PLCs are available on the market, such as LS14500-MER, LS14500-MF, and CR17335SE-MC. These batteries are specially designed to be fully compatible with original batteries, and suppliers typically offer quality guarantees.

05 Battery Replacement Implementation Guide Safe Replacement, Ensuring Continuous System Operation

equipment requires following the correct procedures to ensure safety and system integrity:

Tool Preparation: An appropriate screwdriver set, possibly including Phillips and flathead screwdrivers.

Static Electricity Protection: Wear an anti-static wrist strap or discharge static electricity by touching a grounded metal object before operation.

Document Preparation: If necessary, back up the PLC program beforehand to prevent accidental loss during the replacement process.

Detailed Procedures System Check: Confirm the PLC battery alarm indication or perform preventative replacement according to the maintenance plan. If possible, perform the replacement while the PLC is powered on to preserve memory data.

Safe Power-Off: If replacement must be performed while the power is off, ensure the PLC program and data have been backed up and follow safety procedures to disconnect the power.

Accessing the Battery Compartment: Locate and open the battery compartment door or cover according to the PLC model manual. Some models may require removing a few screws.

Disconnecting the Old Battery: Carefully disconnect the old battery connector, noting the interface orientation for reference when installing the new battery.

Installing the New Battery: Insert the new battery into the connector, ensuring the correct orientation and secure connection. Note the battery polarity; incorrect installation may damage the equipment.

Reset and Testing: Close the battery compartment door, restore power, and check if the system is operating normally, confirming that the battery alarm has been cleared. Restore the PLC clock settings if necessary.

Final Results: After replacement, you will find:

Improved System Reliability: Battery alarms are cleared, and the system operation returns to normal.

Data Security: Programs and data are no longer lost after a power outage, and clock information remains accurate.

Maintenance Cycle Reset: The new battery can provide stable service for several years before needing to be replaced again.

Production Continuity: Avoid unexpected downtime due to battery failure, ensuring production progress.
