Ni-MH batteries (Nickel Metal Hydride)
You can use Ni-MH batteries after charging them with a nickel metal hydride battery
charger. However, improper handling of the batteries may cause leakage, heat generation,
re or explosion. Observe the following.
• If there is dirt on the battery poles, you may not be able to charge normally. Clean the
battery poles and the battery recharger terminals with a soft, dry cloth.
• When charging batteries for the rst time, or after having not used them for a long
period of time, they may not charge fully. This is a feature of Ni-MH batteries and is
not a malfunction. Battery performance will become normal after a few charges and
discharges.
• We recommend charging the batteries after they are fully discharged. If you charge the
batteries before they are fully discharged, it can reduce battery performance. This is
called “memory effect”.
• If “memory effect” occurs, continue using the batteries until the camera stops working
and then charge them fully. Battery performance will be restored after a few charges and
discharges.
• Over time Ni-MH batteries naturally discharge and their capacity lowers even when they
are not used.
• Once the batteries have reached full charge, do not continue to charge them.
• Do not peel off or scratch the covering on Ni-MH batteries.
• Read the operating instructions for the battery charger.
Ni-MH batteries have a limited life. Battery capacity gradually decreases over time. 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.
• Battery life differs depending on the conditions of storage and usage and the
environment.
When not using the batteries for a long period of time
• If the batteries are left in the camera they will discharge. This is because a small
electrical current continues to ow even when the camera is turned off. If the batteries
continue to be left in the camera, they will discharge excessively and may become
unusable even if charged.
• 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
completely discharged.
