Panasonic DVDL50D - Manual (Page 27)

For your reference:
•This product is a rechargeable lithium ion battery pack. It generates electrical energy
through an internal chemical reaction. This chemical reaction is easily affected by tem­
perature and humidity conditions. The effects become more severe as the temperature
increases or decreases. In locations where the temperature is low, the battery pack may
not fully charge, or the CHARGE (CHG) indicator on the player may flash about 5 min­
utes after you start using it. At higher temperatures, a protector circuit may be activated,
making the battery pack inoperative.
• It takes about 6 hours [at 68°F (20°C)] to charge the battery pack and, once fully
charged, the battery will be good for approximately 3 hours of continuous playback (with
the BRIGHT dial set to the center position). However, usage time will differ depending on
the operating condition. (If the brightness is set higher,
bright
the battery operating time will be shorter.)

•The battery pack has a service life of approximately 300 charge-discharge cycles. (It
may depend on the operating condition.) The charging time or operating time on one full
charge will be gradually shorter. If the time becomes noticeably shorter than it used to
be, the battery pack has reached the end of its service life and should be replaced.
• If the player is powered by the battery pack and is left in the STOP mode, the player will
automatically turn off after approximately 5 minutes to conserve battery consumption
(Auto power-off function).
□ Notes when charging the battery pack
•When the battery pack is to be used for the first time, charge it fully before use.
•Upon completion of the charging, be sure to disconnect the power plug from the AC out­
let. (If it is left connected, up to about 2.0 W of power will be consumed.)
□ Notes when using the battery pack
• If the battery pack is not going to be used for a long time, it must be detached from the
player. (If it is left attached, a low level of current will still flow even though the player is
turned off.) If it is left in this state, it may excessively discharge, rendering it unusable
even after it has been recharged.
(Recharge the battery pack before use because the battery pack is discharging even
when it is detached from the player.)
•The AC adaptor is equipped with an overcharge-prevention circuit. However, to protect
the battery pack, be sure to detach it from the player upon completion of the charging.
• For battery pack protection, do not charge an already fully-charged battery pack.
□ Notes when storing the battery pack
•Store the battery pack in areas where temperature is at 59°F-77°F (15“C-25°C).
• Do not store the battery pack in areas of extremely cold or high temperature, high humid­
ity or excessive oily smoke.
•When storing the battery pack for a tong period of time, discharge and fully recharge it
once a year and store it again.
□ Notes when disposing of the battery pack
•Check, and follow, your local regulations before disposal.
