Replacing the Battery
ATCA-7490 Installation and Use (6806800U11F )

The battery provides data retention of seven years summing up all periods of actual data use.
Artesyn 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 does not provide enough power anymore, the RTC is initialized and the
data in the NVRAM is lost.
Therefore, replace the battery before seven years of actual battery use have elapsed.
Data Loss
Replacing the battery always results in data loss of the devices which use the battery
as power backup.
Therefore, back up affected data before replacing the battery.
Data Loss
If installing a different battery type other than what is mounted at board delivery may
cause data loss. 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.
