◎ USE OF PROBLEM AND PRECAUTION FOR POLARON AC/DC SPORTS CHARGER
- The charger has been turned on, but the Screen is off.
. Check that the external power source is an appropriate source.
. This charger should be operated only with the types of power sources that are indicated
on the specifications.
. Please contact the A/S center for additional information.
- The charger does not recognize the batteries.
. Check that the battery connections and the polarity are correct.
. Worn or excessively used cables should be replaced.
. Replace damaged or defective cells in the battery pack.
- Battery voltage is low after the charging process has been completed.
(Cell voltages: NiCd, NiMH less than 1.2V or LiPo, LiIon less than 3.6V or 3.7V)
. Increase the max charge capacity if the final results are too low.
. Control Peak sense of NiCd, NiMH, if the values are too low or high
. Replace worn or damaged charge cables.
- Discharging mode cannot be accessed.
. Check to see if the the preset battery voltage and the cell voltage match.
. Change damaged or defective cells in the battery pack.
- The mAh/time is too low after the charging process has completed.
. The battery may not be fully charged.
. Fully charge the battery and repeat the discharge process. Perform a cycle process to
improve the battery capacity for worn out or infrequently used batteries.
. Reduce the discharge cut-off voltage values that have been programmed too high.
Control the discharge ratio.
. Check that the preset battery voltage and the cell voltage values match.
. For discharging with over current, repeat the discharge process to discharge the
remaining current. For example: for discharging processes exceeding 5A, cool down
the battery and repeat the discharge with 1A.
- Charging Lithium type batteries.
. Use a balance board with an EH to XH cable (MUST).
. Do not charge Lithium battery packs above the maximum charge rate. Using excessive
charge rates can damage the pack and 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.
