The GE Fanuc IC695ACC302 is not just another battery – it is the backbone of your PACSystems RX3i/RX7i controller's data integrity. With a substantial 15 Ah capacity, smart monitoring capabilities, and a robust lithium-ion design, this auxiliary smart battery module ensures that your critical programs, parameters, and real-time clock data remain intact even during unexpected power interruptions. But to truly maximize its value and lifespan, you need to understand how it works and how to care for it properly. Here are practical tips to help you get the most out of your IC695ACC302 battery.

1. Understanding What Your IC695ACC302 Battery Really Offers

At its core, the IC695ACC302 is an auxiliary smart battery module designed specifically for GE Fanuc PACSystems RX3i and RX7i controllers. Unlike standard coin-cell backup batteries, this module provides extended volatile memory backup, safeguarding your downloaded user programs, configuration settings, and process data against loss during main power failures.

What makes it stand out?

Chemistry and Construction: The module is built with three lithium-ion cells, delivering a nominal output voltage of 3 VDC and a substantial 15 Ah capacity (15000 mAh). Its black flame-retardant ABS plastic housing provides durability and fire safety in industrial environments.

2. Common Questions: Backup Duration and Charge Status

One of the most frequent concerns among industrial operators is: how long will the backup actually last? The answer depends on which CPU the battery is paired with and the operating conditions.

Backup Duration Expectations:

With IC695CPU310: Up to 200 days of backup when the battery is in good condition.

With RX7i IC698CPE010/CPE020/CRE020: Approximately 175 days.

With IC695CPU320/CRU320/CPU315: Approximately 23 days total.

3. Charging and Installation Habits That Improve Performance

Unlike consumer electronics batteries, the IC695ACC302 has a unique installation requirement that directly impacts its service life.

Critical Installation Rule:

Always power on the CPU before connecting the IC695ACC302 battery module. If the battery is attached while the CPU is powered off, it will begin to drain immediately, reducing its usable backup time. This is one of the most common – and most overlooked – mistakes that prematurely depletes the battery.

4. Long-Term Storage and Maintenance

Proper storage is critical for preserving the IC695ACC302's shelf life and ensuring it performs reliably when called upon.

Storage Recommendations:

Shelf Life: The module has a nominal shelf life of 7 years when stored at 20°C without the enabling adapter cable attached.

Environmental Conditions: Store in a dry, moderate environment. Avoid direct sunlight, extreme heat, or damp locations that can degrade internal components. The operating temperature range is 0°C to 60°C, and the storage temperature range extends from -40°C to 85°C.

Partial Charge for Extended Storage: If you have spare modules in inventory, consider rotating stock to ensure older units are used first. The battery begins to age from its date of manufacture, indicated by the four-digit date code on the product label.

5. Choosing the Right Battery for Your Needs

While the IC695ACC302 is the standard and recommended auxiliary battery module for most PACSystems RX3i/RX7i installations, there are aftermarket alternatives to consider.

6. Summary: Make Your IC695ACC302 Your Most Reliable Industrial Partner

The GE Fanuc IC695ACC302 Auxiliary Smart Battery Module is more than just a backup power source – it is a critical safeguard for your industrial automation data and operational continuity. By understanding its true capabilities, respecting its installation requirements, adopting proper storage practices, and scheduling regular maintenance, you can ensure years of reliable service from this high-performance battery.
