• Recycle used batteries in a recycle box at your local electronics store or supermarket.
DB-65 Rechargeable Battery
• This is a lithium-ion battery.
• The battery is not fully charged at the time of purchase, so be sure to charge the bat-
tery before use.
• Do not open or damage the battery as this can result in fire or injury. In addition, do
not heat the battery above 60°C (140°F) or expose the battery to fire.
• Due to the battery characteristics, the battery usage time may be shortened when
used in a cold environment, even if the battery is fully charged. Keep the battery
warm by placing it in a pocket or have a backup battery ready.
• When not in use, be sure to remove the battery from the camera or the battery char-
ger. A small amount of current can leak from the battery even when the power is
off, creating excessive discharge and making the battery unusable. If the battery is
removed for more than five days, the date and time settings will be lost. In this case,
reset the date and time.
• If the battery is not used for a long time, charge the battery for 15 minutes once a year
before storing.
• Store in a dry, cool place with an ambient temperature between 15°C and 25°C (59°F
and 77°F). Avoid storing in extreme high or low temperatures.
• After charging the battery, do not immediately charge it again.
• Charge the battery at an ambient temperature between 10°C and 40°C (50°F and
104°F). Charging the battery at a high temperature can deteriorate the battery. Charg-
ing at a low temperature may prevent full charging.
• If the battery usage time becomes very short even when fully charged, the battery
has reached the end of its useful life. Replace with a new battery. Be sure to use a
replacement battery recommended by RICOH IMAGING.
• The recharge time with the AC-U1 is approximately 3 hours (at 25°C (77°F)).
