Batteries and Power supply additional
devices
In order to prevent power waste when not in use, EDAS loggers are
normally delivered with separate battery. Users have to fit the battery
(or any compatible power supply source) in place before starting any
operating procedure.
Main battery
Standard equipment includes
a “D”
size 3,6V - 13,5Ah Lithium battery
Type
Li-SOCl
2
(Lithium)
Brand
SAFT
Model
LSH 20
The average estimated operating life is 4 to 6 months, but always
consider that this estimation depends on:
how often the loggers is activated
how many and what kind of sensors are connected
how often / long the unit is connected to a PC
what environmental conditions the logger works in
