SMART Embedded Computing Penguin Edge MVME250 Series Installation And User Manual page 143

The battery provides seven years of data retention, summing up all periods of actual data
use. Penguin Solutions 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.
When replacing the on-board lithium battery, make sure that the new and the old
battery are exactly the same battery models.
If the respective battery model is not available, contact your local Penguin Solutions
sales representative for the availability of alternative, officially approved battery
models.
Data Loss
Replacing the battery can result in loss of time settings. Backup power prevents the
loss of data during replacement.
Quickly replacing the battery may save time settings.
Data Loss
If the battery has low or insufficient power the RTC is initialized.
Replace the battery before seven years of actual battery use have elapsed.

To prevent damage, do not use a screw driver to remove the battery from its holder.
