Maximum safety
Delta-peak sensitivity: The automatic charge termination program works on the
principle of the Delta-peak voltage detection.(NiCd/NiMH)
Auto-charge current limit: When charging NiCd or NiMH at 'AUTO' current mode,
you can set the upper limit of change current to avoid from high current charging. This
is very useful when charging the low impedance and small capacity NiMH battery in
'AUTO' mode.
Capacity limit: The changing capacity always calculated by multiple of the
charging current and time. If the charging capacity exceeds the limit the process will
be terminated automatically when you set the maximum value.
Temperature limit: The temperature of the battery on charging will rise by its
internal chemical reaction. If you set the limit of temperature the process will be
expired forcibly when the limit has reached.
Processing time limit: you can also restrain the maximum process time to prevent
from any possible defect.
Input power monitor: To protect the car battery using as input power from being
damaged the voltage of it always monitored. If it dorps below the lower limit the
process will be ended automatically.
Automatic cooling fan: The electric cooling fan comes into action automatically
only when the internal temperature of the unit is raised.
Data store/load
For users convenience it can store maximum 5 data of different batteries. You
can establish the data contains program setting of the battery to charge or discharge
continually. These data can be called out at any time you need and the process can
be executed without program setting.

battery refreshing and balancing.
PC based analysis using USB communication
For technical expert, It offers PC based program can analyse the characteristic of
the battery by USB port. It shows a graph of voltage, current, capacity and temperatu
re curves. It also shows the individual voltage of each cell in the Lithium battery pack.
