Technical Manual 1.02, C350 Professional
Internal Li-Ion battery
The C350 pro contains an internal Li-Ion battery for operation even during an external
power fail. Making it possible to report power loses etc. Please note that when external
power is removed the unit will by default be powered down. This setting can be changed
though and is documented in the M2M Control IDE on-line manual. The digital outputs and
the graphical LCD display are also disabled when a power fail occur. Digital outputs due to
that the power supplies both the digital outputs and unit itself. The LCD display because
the internal battery can't provide the supply voltage needed.
The battery charging is completely automated and handled internally by the unit – leaving
no need for user interaction. Different kinds of functions (Battery Low, Charger Enable,
Charging status etc) are available for the user though. Please consult the M2M Control
IDE on-line manual for more information.
The charge current is very high, for shorter charge time, as specified in the technical
specifications; Make sure both power supply and cables can handle the high current.
The battery will be charged whenever a power fail has occurred to establish the capacity
making the battery ready for the next power fail. A maintenance charge will start every
100-hour after the last charge. This is to compensate for the battery self-discharge etc.
The battery cannot be charged above 45°C or below -10°C. The unit will automatically
detect the temperature and terminate the charge process if the temperature is out of this
range.
The temperature has very high influence on the battery capacity. At 0°C the capacity has
dropped to 60% of the initial capacity and it falls dramatically at lower temperatures.
The battery cycle (numbers of charges and discharges) has also influence on the capacity.
After 300 cycles the capacity has dropped to approximately 80% of the initial capacity.
Warning:
Misusing the C350 pro unit may cause the built-in battery security circuit to be damaged.
• Do not place the unit in high temperature locations such as direct sunlight or near
engines. Using the unit in this environment may result in loss of battery
performance and a shortened life expectancy.
• Do not expose the unit to water, salt water or allow the battery to get wet.
• Avoid strong impacts and shocks.
For more information regarding the environmental limitations see "Specifications for C350
pro" below or consult the C350 pro Datasheet.
