The IC693ACC302B is an external, high-capacity Auxiliary Battery Module designed to significantly extend memory retention across various GE PLC families, including the Series 90-30, Series 90-70, and PACSystems CPUs. By directly replacing standard low-capacity CPU batteries, this heavy-duty power source ensures long-term data security during extended power outages.
Works with legacy GE Series 90-30, Series 90-70, and PACSystems CPUs
Replaces standard CPU batteries directly to provide longer-lasting memory retention
Extends RAM backup time up to 75 months for standard units, and 15 months for the CPU374
This auxiliary battery module serves as a hardware protective component within General Electric's process control framework and is widely utilized in industrial automation loops requiring long-term continuous operation. In actual system deployments, it functions not only as a dedicated peripheral hardware for the Series 90-30 and Series 90-70 Programmable Logic Controller families but also directly bears the heavy responsibility of safeguarding underlying core data within Mark I and Mark II gas turbine control systems.
When an industrial field experiences sudden localized power outages, main grid drops, or control cabinet shutdowns due to equipment maintenance, this module delivers a constant low-voltage current to the Random Access Memory on the central processing unit motherboard via its own low-impedance connecting lead wires. This continuous electrical support ensures that user ladder logic control programs, process variables, system parameter configuration files, and lower-level register data stored in the memory remain intact under unpowered conditions, preventing production stoppages caused by data erasure.

Used for controller data backup in auxiliary workshops such as coal handling, slag removal, and chemical water treatment.
Papermaking & Pulp Processing
Locks critical tension and blending parameters in large continuous digesting, bleaching, and headbox controls.
Cement & Building Materials Production
Provides long-term retention of operating parameters in PLC control systems for large rotary kilns and raw material mills.
Rubber & Tire Manufacturing
Used for backing up complex time-temperature stepping logic in internal mixers and tire curing presses.
Mining & Mineral Flotation
Used for the long-term storage of agent ratios and agitator current monitoring in large ball mills and flotation machines.
Wharves & Port Lifting Machinery
Used for protecting anti-sway and anti-collision algorithm parameters in heavy lifting equipment like quayside cranes and ship unloaders.
Never disconnect or replace this battery while the PLC is powered off because this will cause an instant loss of all programs and data in the RAM. Replacements must only be performed while the main system power is fully active. Do not recharge, disassemble, heat, or short-circuit this lithium module as it poses a severe risk of explosion or fire. Finally, monitor the battery status regularly via software or system LEDs. Replace it immediately when the low-battery (BATT) alarm trips or as it approaches its service limit of 75 months for standard CPUs or 15 months for the CPU374. Always dispose of expired units safely following MSDS guidelines.
The GE IC693ACC302B is a high-capacity external Auxiliary Battery Module for rugged industrial automation. As a critical accessory for legacy GE Series 90-30 and 90-70 PLC systems, it supplies a stable, long-term 3V DC voltage to the CPU RAM during system or backplane power outages. This ensures that critical configuration parameters, runtime process data, register values, and core application logic remain completely intact.
It is an industrial-grade auxiliary lithium battery module manufactured by General Electric, specifically used to provide power-off data retention for its PLC processor memory.
What is the chemical composition of the internal battery in IC693ACC302B?
It encapsulates a highly stable industrial-grade high-energy Lithium Thionyl Chloride (Li-SOCl2) battery internally.
How to correctly install and connect the IC693ACC302B in an industrial field?
The module is usually mounted on a dedicated bracket inside the control cabinet, and its built-in twisted-pair lead wire with a locking connector plug is inserted directly into the battery port of the PLC processor or baseplate.
How to store unsealed spare IC693ACC302B modules before use?
t should be stored in a dry, cool warehouse environment with minimal temperature fluctuations, and storage temperatures exceeding 26°C must be avoided to prevent accelerated internal self-discharge.
What safety restrictions apply to the IC693ACC302B module during factory shipping or air logistics?
Because it contains lithium metal, air or international logistics must strictly comply with UN3090 or UN3091 Class 9 hazardous goods transportation safety packaging regulations.
