Rechargeable Ni-MH batteries
●
You can use Ni-MH batteries after charging them with a dedicated battery charger.
However, improper handling of the batteries may cause leakage, heat generation, fire
or an explosion. Observe the following.
• If there is dirt on the battery poles, you may not be able to charge the batteries
normally. Carefully clean the battery poles and battery charger terminals with a soft
dry cloth.
• Do not peel off or scratch the covering on Ni-MH batteries.
• When the batteries are used for the first time, or after having not been used for a long
period of time, they may not fully charge. This is a characteristic of Ni-MH batteries
and is not a malfunction. Battery performance will return to normal after a few
charges and discharges.
• We recommend charging the batteries after they are fully discharged. If you repeat
charging before they are fully discharged, battery performance may be reduced. (This
is called "memory effect".)
If a "memory effect" occurs, continue using the batteries until the camera can no
longer perform recording or playback and then charge them fully. Battery performance
will be restored after a few charges and discharges.
• Once the Ni-MH batteries have reached full charge, do not continue to charge them.
• Over time, Ni-MH batteries naturally discharge and their performance lowers even if
they are not used. If the batteries are left in the camera in this condition, they will be
drained excessively and may become unusable even if they are charged again.
• When storing the batteries for a long period of time, we recommend charging them
once a year. Remove the batteries from the camera and store them again after they
have been completely expended.
• Ni-MH batteries have a limited life. Battery performance gradually decreases over
time as you keep using them and time goes by. If the length of time you can use
the camera is extremely short even after fully charging the batteries, they may have
exceeded their life span. Purchase new batteries.
• Read the operating instructions for the battery charger.
