Explosion Hazard - Recharge battery only in a non-hazardous location. Do not connect or
disconnect the battery charger unless the area is known to be non-hazardous. The

2.6 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.
Please refer to the Battery Compatibility and Memory Retention Time in Days at 20°C chart for CPU compatibility
information.

Operating temperature range
2.6.1.2 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.
