◎ USE OF PROBLEM AND PRECAUTION FOR POLARON EX 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.

◎ NEW BATTERY CHARGE
- When the new NiCd/ NiMH are charged at the first time, charge process might be
terminated within minutes, it is not because charger or battery have a problem, but
because battery is not stabilized yet. In this case, you need to charge battery after
increasing the delta peak value or to charge battery after discharging and cooling down
battery.
Do not use the battery, if the charged capacity of battery exceeds battery capacity in
specification. If such a phenomenon arises, repeat to charge and discharge more over 5
times and charge again.
◎ 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
◎ LiIon, LiPo, LiFe BATTREIES SAFETY
- Always charge the batteries that have Lithium ion or Lithium polymer mark and do not charge
the batteries that have Lithium mark. Failure to do so will damage the batteries and may cause
fire or personal injury.
- Always charge the batteries that the cell voltage ( 3.3V / 3.6V / 3.7V ) is written
- Ensure that the charger and battery are placed on a non-flammable surface whilst charging.
- Never charge Lithium ion/Polymer/Fe batteries inside a vehicle whatever the circumstances.
- Always ensure that the charger is correctly set for the battery being charged, checking both
voltage and capacity. Be particularly careful if using a series/parallel battery pack, or if using
packs of different specifications with the same charger.
- Never charge at a rate higher than that recommended by the cell manufacturer, this can be
very dangerous.
- Do not leave Lithium ion/Polymer/Fe batteries unattended whilst they are charging. Monitoring
the batteries during charging is very important.
- Always monitor the temperature of the battery being charged every few minutes. If the battery
becomes hot to the touch, disconnect it from the charger immediately and allow to cool. Do not
recommence charging until the battery and charger have been checked for compatibility and the
charger settings have been confirmed as being correct.
- In the unlikely event of the Lithium ion/Polymer/Fe battery catching fire DO NOT use water to
attempt to put the fire out, instead use sand or a fire extinguisher designed for electrical fires.
