COMMON PROBLEMS AND PRECAUTIONS FOR THE POLARON PRO DC CHARGER
TURNING ON THE CHARGE,
BUT LCD SCREEN IS OFF
Check if the correct external power source, this charge should be operated only from
the type of power source indicated on the specification. In case that the problem is
not settled, please contact A/S center.
THE CHARGER DOESN’T
RECOGNIZE BATTERY
Check if the battery connection and polarity are correct.
Change the cable if the worn out cable is used.
Change the damaged cell in battery pack if a cell is damaged.
BATTERY VOLTAGE IS LOW
AFTER CHARGING
(Each cell voltage of NiCd, NiMH is lower than 1.2V or each cell voltage of LiPo, LiIon is
lower than 3.6V or 3.7V)
Increase the max charge capacity if it is too low.
Control Peak sens of NiCd, NiMH if it is too low or high and change the charge cable if
the worn out cable is used.
DISCHARGING MODE IS NOT
ACCESSED
Match the preset battery voltage and the cell voltage.
Change the damaged cell in battery pack if a cell is damaged.
mAh/Time IS TOO LOW
AFTER CHARGING
Battery might not be fully charged, fully charge battery and discharge again.
Perform cycle to improve battery capacity if battery is worn out or not used for a long
time.
Reduce discharge cut off voltage if it is programmed too high and control the
discharge ratio.
Match the preset battery voltage and the cell voltage.
When to discharge with over current, make sure to discharge the remained current
again. For example, when to discharge with higher than 5A, cool down the battery
and then discharge with 1A again.
CHARGE LITHIUM TYPE
BATTERY
Make sure to use a balance board and must use EH to XH cable.
Do not charge Lithium battery packs above their maximum charge rate. This can
damage the pack and can be dangerous. Generally, Lithium Polymer packs should
not be charged above 3C. However, some newer packs do allow charging at up to 5C,
but charging at these higher rates will reduce the life of the pack.

NiCd, NiMH BATTERY SAFETY
With charging new NiCd/ NiMH batteries for the first time, the process may terminate within minutes. This stoppage
does not indicate a problem. This stoppage results from an unstabilized battery. To stabilize the batteries, charge
the batteries either after increasing the delta peak value or after performing a discharging process followed by a cooling
down period.
Do not use the batteries, if the charged capacity of the battery exceeds the specifications for the battery capacity. If you
experience repeated terminations upon charging, repeat the charge and discharge process by at least 5 times and then
repeat the charging process.
Premature terminations may occur up to the third time that the battery has been charged.
25.
Pb BATTERY SAFETY
Pb battery needs to be charged every day. If the charged capacity of battery is dropped below 50%, this battery might
not be recharged. The average charge time of Pb battery is 4~5 hours. Do not charge an automobile battery, the charger
might get the serious damage
