- Water & wastewater treatment plants — maintains SCADA-linked PLC programs through utility grid fluctuations
- Food & beverage processing — preserves time-stamped batch records and PID parameters across shift changes
- Oil & gas upstream/midstream facilities — protects control logic in remote RTU cabinets subject to harsh power conditions
- Pharmaceutical manufacturing — supports 21 CFR Part 11 audit-trail continuity by preventing data loss events
- Building automation & HVAC — keeps scheduling and setpoint data intact during routine maintenance windows

Why Engineers Specify This Model
- OEM-matched chemistry — GE-specified lithium cell ensures voltage curve compatibility with the Series 90-30 low-battery detection circuit, avoiding false alarms
- Plug-and-play replacement — no programming required; swap during a maintenance window without losing user program or retentive data
- Extended shelf life — factory-sealed cells retain >90% capacity for up to 3 years in storage, reducing spare-parts obsolescence risk
- Dual protection — simultaneously backs up both user RAM (ladder logic, data tables) and the real-time clock (RTC), critical for time-stamped alarm logs
- Low total cost of ownership — a single IC693ACC302 protects a CPU investment worth 10–50× its own cost

Application-Specific FAQ
Q: How do I know when the IC693ACC302 battery needs replacement?
A: The Series 90-30 CPU generates a LOW BATTERY fault (fault code 0x0083) in the PLC fault table. Proficy ME will also display a battery alarm in the hardware configuration status. Replace proactively every 2–3 years in 24/7 operations.
Q: Can I replace the battery while the PLC is powered on (hot-swap)?
A: Yes — GE recommends replacing the battery with the CPU powered ON to avoid any risk of RAM data loss. The CPU continues to power RAM from the backplane supply during the swap. Total swap time should be under 60 seconds.
Q: Will the IC693ACC302 work with Series 90-70 or PACSystems CPUs?
A: No. The IC693ACC302 is exclusively designed for Series 90-30 CPUs. For Series 90-70, refer to IC697ACC701; for PACSystems RX3i, refer to IC695ACC402.
Q: What happens if the battery is completely depleted?
A: The CPU will lose all retentive data (user program, data tables, RTC). The CPU will fault on power-up and require a full program download from Proficy ME before resuming operation. No hardware damage occurs.
Q: Is this battery classified as hazardous goods for air freight?
A: Lithium primary cells are regulated under IATA DGR Section II (PI 968). Konmask ships in compliant packaging with proper UN3090 labeling. Please advise if your project requires air freight so we can prepare the correct documentation.
