Legacy Batteries

2.6.1

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.

CPU Battery Low Indication
The legacy batteries will not reliably provide the CPU with a battery low indication. User logic
should not rely on any of the battery status bits when using these batteries.
2.6.2

IC693ACC302

The IC693ACC302 Auxiliary Battery module provides an extended backup time for volatile
memory on PACSystems CPUs compared to that of the standard memory backup battery
(IC698ACC701).
