Analysis Function
The analysis function can be applied to a battery that is under-performing or if you
would like to examine performance in general. This function can also be used to
identify and match the working capacities of batteries.
Activation Function
Occasionally a NiCd or NiMH battery may become so discharged that it can no
longer be recharged under normal conditions, especially if the voltage is extremely
low. Battery activation uses a low current to perform an activation cycle which will
charge, discharge, then charge the battery. The battery will be activated during this
process but will sometimes require up to three cycles. If the battery still cannot be
activated, then do not continue and dispose of the battery.
Internal Resistance Measurement Function
The charger is equipped with a function for measuring the internal resistance of
individual cells. The internal resistance is measured and calculated after the charging
task has been initiated for 10 seconds.
When the charger measures the internal resistance of the battery, it will instantly
adjust the charging current, so it is normal for sudden changes to occur in the
current during the charging process.
Due to the way the device measures internal resistance, the size of the charging
current can impact the accuracy of the internal resistance measurement.
A battery with large capacity and low internal resistance requires a larger charging
current to accurately measure the internal resistance.
Charging Completion
After beginning a task, progress will be displayed in the task quick preview bar.
“ ” will be displayed when the task is completed. It is normal for voltage decline
to occur once charging completes. As the number of charge cycles increases, the
performance of a battery decreases, and voltage decline becomes more obvious.
Charging a battery with a larger current will also cause a greater decline in voltage
after the charging is complete.
Battery short circuit and
reverse polarity protection
When a battery has been inserted with
the wrong polarity the corresponding
slots status will be displayed as below:
Battery polarity reversal!
