Battery Exchange; Replacing The Battery - SMART Embedded Computing ATCA-F125 Assembly, Installation And Use

Battery Exchange

A.1

Replacing the Battery

The battery provides data retention of seven years summing up all periods of actual data
use. SMART Embedded Computing therefore assumes that there is usually no need to
replace the battery except, for example, in case of long-term spare part handling.
Board/System Damage
Incorrect replacement of lithium batteries can result in a hazardous explosion.
Therefore, replace the battery as described in this chapter.
Data Loss
If the battery voltage drops below the minimum required level, the RTC time will be
lost.
Therefore, replace the battery before seven years of actual battery use have
elapsed.
Data Loss
Replacing the battery will result in RTC data loss. The RTC will have to be re-
initialized after the battery is replaced.
Data Loss
Installing another battery type other than what is mounted at board delivery may
cause limited operation. This is because other battery types may be specified for
other environments or may have a shorter lifespan. Therefore, only use the same
type of lithium battery as is already installed.
Replacement Procedure
To replace the battery, proceed as follows:
1. Remove the battery. See
PCB and Battery Holder Damage
Removing the battery with a screw driver may damage the PCB or the battery holder.
To prevent this damage, do not use a screw driver to remove the battery from its
holder.
2. Install the new battery following the "positive" and "negative" signs.
