Notes
This charger is designed to fully charge batteries regardless of their energy level. However, for best
results when charging newly purchased batteries or batteries that have not been used for a long time
(more than one month), It is recommended to fully charge the batteries, then discharge them. Repeat
two or three times.
• When you dispose dead batteries always observe the laws and regulations regarding the disposing of such
items.
• If Ni-MH rechargeable batteries are not fully discharged, protect against short-circuiting (e.g. by taping the
contacts) before disposing.
For customers in Germany
Olympus has a contract with the GRS (Joint
Battery Disposal Association) in Germany to
ensure environmentally friendly disposal.
Discharging
Batteries self-discharge while they are not in use. Be sure to charge them regularly before use.
Battery life
Charging and discharging are possible for approximately 500 times depending on usage.
Operating temperature
Batteries are chemical products. Battery efficiency may change even when operating within
the recommended temperature range, but this is not a malfunction.
Recommended temperature range for use
Discharging (when using appliance): 0°C - 50°C/32°F - 122°F
Charging: 0°C - 40°C/32°F - 104°F
Storage: –20°C - 30°C/–4°F - 86°F
Using the batteries outside the above temperature range may result in declining efficiency
and shorter battery life.
In order to prevent battery leakage or rust, remove the batteries from the products when you
will not be using them for a long time, and store them separately.
