Battery Storage and Operation (Model 4123)
The standard battery incorporated into the ATEX certified 4123 is designed as a backup power source.
In the instance of a loss of primary power, the computer will run off of its Lithium-Ion battery. The battery
pack is a 14.4VDC, 2.9 Ah pack in a compact form factor. As such, it will only run the computer for up to
approximately one (1) hour. It can be used in short cycles solely on battery, however it is recommended
that the 4123 is used as a mounted, hardwired computer.
Charging: The battery charges when the unit is connected to its power source, and ends its charge cycle
when at full capacity. A full charge will take about three hours to charge.
Storage: Though the battery is embedded in a weather resistant enclosure and the 4123 storage
temperature is -20°C to +55°C, it is recommended that the battery not be subjected to long term storage at
a temperature outside -20°C to +60°C. For ideal battery life, the battery should be within 30-50% capacity
before placed into storage.
Life Expectancy: Under normal use and storage, the battery can be expected to deliver 80% or more of its
initial capacity after 300 charge cycles.
