Check Point
Is the power cord connected?
Will another battery accept a charge?
Are a Ni-MH battery and a Li-ion
battery connected at the same time?
Can another battery be charged?
Is the battery temperature appropri-
ate?
Is the ambient temperature appropri-
ate?
Is the temperature of the battery
high?
Are you refresh charging the battery?
Check the number of times or days
you have used the battery.
Is the sound unusual?
While the charger is charging the bat-
tery, it is normal for the unit to heat up
to some degree (about 104–140 °F,
about 40–60 °C). If the charger gets
too hot, though, it may be malfunc-
tioning.
Does this occur immediately after you
start using the charger?
What to Do
Connect the power cord to a power
source.
If it can be charged, the charger is nor-
mal. Use a rechargeable battery.
If it cannot be charged, the charger may
be faulty. Contact your dealer.
The charger has remained in standby
mode for a long time and has stopped
charging the battery.
Wait for the battery temparature to drop
and try to charge the battery again.
If both are connected at the same time,
disconnect one of them.
If it can be charged, the charger is nor-

Wait until the battery reaches an appro-
priate temperature.
Charge the battery in an environment with
an appropriate temperature.
After the battery has cooled down, try
charging again.
The battery is being discharged. Refresh
charging will take 3 to 19 hours.
Has the battery deteriorated?
After approximately 300 charge/discharge
cycles, the battery capacity will decrease
to approximately 60% of that of a new
battery.
Unplug the power plug, stop charging the
battery and contact your dealer.
Unplug the power plug, stop charging the
battery and contact your dealer.
The charger may emit an odor immedi-
ately after it is put to use, but the odor will

tact your dealer.
