Battery Exchange
MVME4100ET Single Board Computer Installation and Use (6806800K76F) 112
The battery provides data retention of seven years summing up all periods of actual data use.
Artesyn therefore assumes that there usually is no need to exchange the battery except, for
example, in case of long-term spare part handling.
Board/System Damage
Incorrect exchange of lithium batteries can result in a hazardous explosion.
When exchanging the on-board lithium battery, make sure that the new and the old battery
are from exactly the same battery manufacturer and of the same models.
If the respective battery model is not available, contact your local Artesyn sales
representative for the availability of alternative, officially approved battery models.
Data Loss
Exchanging the battery can result in loss of time settings. Backup power prevents the loss of
data during exchange.
Quickly replacing the battery may save time settings.
Data Loss
If the battery has low or insufficient power the RTC is initialized.
Exchange the battery before seven years of actual battery use have elapsed.
PCB and Battery Holder Damage
Removing the battery with a screw driver may damage the PCB or the battery holder. To
prevent damage, do not use a screw driver to remove the battery from its holder.
