Sony SPP-D900 - Manual (Page 5)

Basics
When to charge the battery pack
As long as the handset is placed on the base unit after each call, the
battery pack will be recharged continuously.
If the handset battery becomes weak
You will hear a beep every three seconds during the conversation.
The call will be di.sconnected in one minute.
When to purchase a new battery pack
If the battery la.sts only a few minutes even after 18 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-T18 rechargeable battery pack.
Note
If the handset battery is completely discharged, the digital security code will be erased
and all programmed numbers will be lost from memory.
In this case, first recharge the battery for more than 18 hours, then store the numbers
into the memory for speed dialing again (see page 17). The security code will be
automatically set when you replace the handset onto the base unit.
