Battery duration
A fully charged battery pack lasts for about:
• 6 hours when you use the handset continuously
• 10 days (RING ON mode) or 1 month (RING OFF mode) when the
handset is in standby mode.
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 to its full capacity.
• While charging, the battery pack warms up. This is not a malfunction.
To obtain the best performance from the 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-T24 rechargeable battery pack.
step 3: Preparing the battery pack (continued)
Note
Battery life may vary depending on usage condition and ambient temperature.
