The IC698ACC701C coin cell battery pack is an enhanced version of the IC698ACC701B battery pack. In addition to providing standard memory backup for PACSystems CPUs, the smart coined cell battery pack has a battery monitoring circuit that enables the user to detect the Low Battery state in advance before it is completely drained.

Pre-installation Check
Upon receiving the battery pack, verify the package contents, which include the following:
IC698ACC701C (or later) Smart Coin Cell Battery pack having cable with four-pin female JAE
connector
Enabling adapter cable with four-pin male to two-pin female connector
Date Code
The date code is located on the product label at the right bottom edge. The date code consists of four digits,
such as 1011. The first two digits represent the year of manufacture in the 21st century, such as 10 for the
year 2010. The last two digits represent the fiscal week of manufacture for the indicated year; for example 11
stands for fiscal week 11.
Installation
1. While installing the battery to the CPU, first connect the four-pin Male JAE connector on the enabling
adapter cable to the female four-pin JAE connector on the battery pack as shown in the following figure.
(Installing the four-pin connector enables the battery.)
Note1: The battery will begin to drain immediately if attached to the CPU in Power OFF condition. To
maximize battery life, it is recommended that you install the fresh battery after power has been turned
ON to the attached CPU.
Note2: Once the enabling adapter cable is connected, the battery starts to drain, even if it is not attached to
the CPU. So, it is recommended to disconnect the enabling adapter cable from the battery pack when
the battery is not in use. Even though the discharge current would be negligible with just the enabling
adapter cable connected, this can affect Battery life if left in this condition for long durations
Connect the two-pin female connector of the enabling adapter cable to the CPU battery terminals.

Run the battery cable into the notch at the
bottom of the battery compartment and
close the battery door.

Run the battery cable
through the slot on
the battery door and
reinstall the battery

Nominal Memory Backup Life*
The battery pack retains dynamic data in the controller SRAM and is only active when the system is not
powered up. The number of days in the Nominal Battery Backup Life table below represents the approximate
number of days the battery will back up the SRAM during times only when the CPU is not powered.
Example: If the CPU is powered down only on weekends, the Battery will last 63 days in Good State and 52
days in Low State. The total battery life will be approximately 115 days before it should be
replaced. Unscheduled power outages and temperature changes will reduce the number of days
and should be considered when calculating the duration of the battery life.

*The nominal backup values are estimated at 20ºC. Backup time increases approximately 17% at 60ºC and
decreases approximately 32% at 0ºC.
Note: The CPU detects the low battery condition only while the CPU has power. If a low battery condition
occurs while the CPU is powered down, the CPU logs a Low Battery fault upon powerup as soon as it
detects the signal from the smart battery.
However, because the current drain on the batte
Smart Battery Operation
The battery output voltage is > 2.5 V when the battery is operating in its good state. At the end of the battery
good period, the battery output drops to <2.5 V for the battery low state. The period for the battery low state is
15 days for all CPU models. Once battery output voltage drops to <2.5V, the PACSystems CPU detects this
as a battery low condition, a Low Battery fault is logged in the CPU fault table and the Battery LED on the
CPU starts blinking in red(depending upon the CPU).
Once the battery low state is active, the user has 15 days of accumulative battery backed energy left for CPU
RAM retention during power loss. If the battery is not replaced within 15 days of accumulative power loss, the
CPU RAM memory contents will be lost as the battery output voltage drops to 0V.
If the Battery Low condition occurs when the controller is in the Power OFF state, a low battery fault will be
logged in the Fault table only at the time when the controller is powered ON. The Battery Low period of 15
days is counted as soon as the Battery Good period is over, but not necessarily when the low battery fault is
logged.
Consider the following scenario.
Battery Good Battery Low
Controller Power Down Controller Power Up
A B
Battery Low period starts Battery Low fault logged
The Battery Low period of 15 days starts at Point A, but the low battery fault is logged only at Point B, once
the controller is powered ON. So, the user should make a note that the timestamp of the Low Battery fault
may not give the exact start of the 15 days Battery Low period.
Note: This battery is not supported on all the PACs CPUs. The table shown below lists the compatible
CPU models.
