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.

If you suspect 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).

NOTE

The battery command applies only to the internal battery of the

logger.
