Battery performance
In ideal conditions, a fully charged battery should give up to 10 hours talk time or 100 hours standby time on a single charge.
Note that new batteries do not reach full capacity until they have been in normal use for several days.
To keep the battery in the best condition, leave the handset off the base for a few hours at a time. Running the battery right down at least once a week will help it 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. New batteries are available from the BT Verve 450 Helpline on 0800 218 2182*.

icon will be displayed.

telephone line cord into the socket marked 
on the rear of the base and the other end into the telephone wall socket.
