Battery Status
You can view battery status information by giving the command
battery
without parameters.
Example:
/ > battery
Remaining=100
State=FLOAT_CHARGE
U=6.850195
I=2.685547
Type=PB_BATTERY
Capacity=1.200000
Ext.DC=8.132420
Internal temperature=23.511668
Battery voltage (U) and voltage at the +ExtDC terminal are given as
volts, charging current (I) as milliamperes and capacity as ampere-
hours. The remaining percentage shows how much energy is left in the
battery.
When is suspected that the internal battery or the charging circuitry is
defective, try the following:
- Check that the battery capacity is correct and change it with
battery <capacity>
command, if necessary. If the capacity setting
is too low, the battery simply charges slowly. In the opposite case,
the battery may be damaged due to too high charging.
- Check the battery voltage, ExtDC voltage and charging current.
ExtDC should be higher than battery voltage for charging. If it is
lower, battery is discharging and charging current shows negative
value. Normally, battery voltage should vary between 5.8 and 7.0
volts and it may rise as high as 7.5 volts during Quick Charge (for
lead batteries).
Determining MAWS Operation Mode
You can look at the status LED to determine the MAWS operation
mode. The LED is located on the MAWS logger board (see Figure 4
on page 24). First, you have to open the tube as instructed in section
Installing MAWS Basic Components on page 53.
