4.9 Battery
This screen displays the charge capacity of the battery. Two battery types are
available with the AT-10plus.
• Lithium
• NiMh
The battery type is automatically detected by the unit and is calibrated in the factory.
It should not need recalibrating during its life. However, if the battery capacity seems
limited when the battery gets older, it can be recalibrated at any time. The battery
must also be recalibrated when a new one is installed. The information given on this
screen is as follows:
Discharge Count
This is a hardware counter directly from the battery charge controller. It counts (to a
maximum of 16000), to show battery discharge when the unit is switched on (but not
connected to the mains).
Charge Count
This is a counter directly from the (hardware) charge controller. It is a counter (to max
16000) showing battery charge rate when the battery is charging.
Self dis. Count
This is a counter directly form the (hardware) charge controller. It is a counter (to max
16000) showing battery leakage rate when the unit is not switched on and not
connected to the mains.
Saved Energy
The three counters (registers) above, have a maximum count of 16000. When any
counter reaches 16000, all the hardware counters are reset. The saved energy count
here is an accumulative figure of the three counts above (when reset) i.e.
• (Charge count) - (Discharge count) - (Self dis. Count)
NiMh full value
This is the capacity of the (NiMh) battery (calculated when the battery is calibrated).
The typical value of a new battery is 4000 - 6000.
Li full value
This is the capacity of the (Li) battery (calculated when the battery is calibrated). The
typical value of a new battery is 2500 - 4000.
Note: the battery type is automatically detected by the unit and only one of the above
values (‘NiMh full value‘ or ‘Li full value‘) will be displayed. The type of battery installed
in shown in the Li / NH field (see following).
