GE IC698ACC701 – Backup Battery Pack for PACSystems RX7i CPU Memory Retention

The GE IC698ACC701 is a dedicated backup battery pack designed for PACSystems RX7i controllers. In day-to-day terms, it keeps your RX7i CPU’s RAM and real-time clock alive when main power goes down. From my experience, facilities that run 24/7 typically keep one or two of these on the shelf—because a quick swap can prevent configuration loss and an unexpected line restart.

Company’s Order Placement Process and Guarantees

• Delivery: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment, full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Purpose-built for RX7i CPUs – Works with PACSystems RX7i controllers (e.g., IC698CPE-series) to retain volatile memory and RTC when power is removed.
• Simple field replacement – Tool-less, plug-in style connector. You can typically swap it during a scheduled stop in a few minutes.
• Stable lithium chemistry – Designed for long-term standby; in many cases it supports multi-year retention depending on CPU load and ambient conditions.
• Prevents unexpected program loss – Helps avoid reloading logic and retuning after outages; one thing I appreciate is how it reduces restart time risk.
• Low maintenance – No ongoing service other than periodic health checks and timely replacement.

Related or Supporting Products

• IC695ACC302 – Battery pack for PACSystems RX3i; similar role but for the IC695 family.
• IC693ACC302 – Battery pack for Series 90-30; a common spare when supporting mixed legacy systems.
• IC698CPE010 / IC698CPE020 – RX7i CPUs that typically use IC698ACC701 for memory retention.
• IC698PSA300 – RX7i power supply module; keeping a healthy PSU plus a fresh battery reduces unplanned downtime.

A maintenance supervisor told us they swap these on a 3–5 year interval “before” alarms start popping up. You might notice, when the battery nears end-of-life, the CPU will log a low-battery status—handy if you’re tracking health in SCADA.

Installation & Maintenance

• Panel environment: Mount the RX7i rack in a clean, dry, ventilated cabinet (typically per IEC/UL industrial enclosure standards). Avoid heat sources that accelerate battery aging.
• Wiring & handling: De-energize the cabinet when practical and follow ESD precautions. If hot-swapping is permitted by your CPU model, maintain power to preserve memory—verify in the CPU manual.
• Connection: Locate the CPU battery header, disconnect the old pack, and plug in IC698ACC701 firmly until latched. Route the lead away from fans or sharp edges.
• Safety: Do not short, crush, recharge, or incinerate the lithium pack. Use approved recycling streams for spent batteries.
• Routine checks: Review the CPU’s battery status bit in your diagnostics. Replace proactively if alarms occur or during major turnarounds.
• Firmware & backups: Keep the CPU firmware current and export a copy of your application before any maintenance. It seems to save headaches if schedules slip.

Quality & Certifications

• Manufactured to GE’s industrial standards for PACSystems RX7i accessories.
• CE compliant; RoHS status typically available for current production lots.
• UL/cUL recognition applies where specified by the OEM documentation.
• Seller warranty: 365 days from shipment.

Tip from the field: label the install date on the battery lead. In most cases, that tiny note makes future service faster—and keeps everyone honest about replacement intervals.
