Sony SPP-S9001 - Manuel (Page 6)

Battery duration
A fully charged battery pack lasts for about:
• Approx. 6 hours when you use the handset
continuously.
• Approx. 7 days (RING ON mode) or three weeks
(RING OFF mode) when the handset is standing
by.
Notes
• The battery pack will gradually discharge over a long
period of time, even if not in use.
• If you leave the battery pack in the handset without
charging it, the battery pack will be completely
discharged. It may require several times of charging to
recover its full capacity.
• While charging, the battery pack warms up. This is not a
malfunction.

To obtain the best performance from battery
Do not place the handset on the base unit after each call. The battery works best if the handset
is returned to the base unit after two or three calls. However, do not leave the handset off the
base unit for a long period of time as this will completely discharge the battery pack.
When to purchase a new battery pack
If the battery lasts only a few minutes even after 12 hours of charging, the usable life of the
battery has expired and needs replacement. Contact your local Sony authorized dealer or
service center, and ask for Sony
BP-T31 rechargeable battery pack.
Note
Battery life may vary depending on usage condition and ambient temperature.
