BATTERY PERFORMANCE
In ideal conditions, fully charged batteries should give up to 12 hours talk time or up to 250
hours standby time on a single charge.

Note that new batteries do not reach their full capacity until they have been put to normal
use for several days.
To keep your batteries in the best condition, leave the handset o the base for a few hours
at a time.
Running the batteries right down at least once a week will help them last as long as
possible.
The charge capacity of rechargeable batteries will reduce with time as they wear out,
giving the handset less talk / standby time. Eventually they will need to be replaced.
After charging your handset for the rst time, subsequent charging time is about 6–8 hours
a day. Batteries and handset may become warm during charging. This is normal.

All talk and standby times are approximate and depend on features selected and usage
pattern.
