Cause

The alarms are expected behavior. As there are no FMODs installed in the associated EXP, the ESM will not be charged and it will persistently report a Low Battery status.

If FMODs are ever installed in either EXP2 or EXP3, then the Charging Status for the associated ESM will change (to "Charging") and the Low Battery status will be cleared.

Solution

As this is normal behavior, no action is needed. Replacing an ESM is not required.
