Sony DSC-W570 - Manual (Page 198)

The remaining charge indicator may not be correct under certain circumstances.
When [Power Save] is set to [Standard] or [Stamina], if you do not operate the camera for a
certain period of time while the power is on, the LCD screen becomes dark, then the camera
turns off automatically (Auto power-off function).
How to store the battery pack
Fully discharge the battery pack before storing and store it in a cool, dry place. To maintain
the battery pack’s function, fully charge the battery pack and then fully discharge it on the
camera at least once a year while storing.
To use the battery pack up, leave the camera in slideshow playback mode until the power
goes off.
To prevent staining the terminal, short-circuiting, etc., be sure to use a plastic bag to keep
away from metal materials when carrying or storing.
On battery life
The battery life is limited. Battery capacity decreases over time and through repeated use. If
decreased usage time between charges becomes significant, it is probably time to replace it
with a new one.
The battery life varies according to how it is stored and the operating conditions and
environment in which each battery pack is used.
Compatible battery pack
The NP-BN1 (supplied) can be used only in N type compatible Cyber-shot models.
