IC698ACC701A and IC698ACC701B

The IC698ACC701B (and earlier revisions) coin cell battery pack is a simple battery pack that
provides backup for volatile memory on PACSystems CPUs. The chemistry used in these
batteries does not support the low-battery detection feature. Due to the limited capacity of
this battery pack, it is not compatible with all PACSystems CPUs. Refer to the Battery
Compatibility and Memory Retention Time in days at 20°C (68 °F) chart for CPU
compatibility information.
