8 Replacing the Batteries
The internal lithium batteries of the Sebalog D are able to supply a constant voltage
level over a long period. Under ideal conditions, a logger can be operated for up to
five years without changing the batteries. The voltage level can be read off from the
Voltage parameter in the logger configuration window (see section 5.7).
Empty batteries can not be recharged but can be single-handedly replaced by
batteries of the same type.
Introduction
