Battery performance

To keep your batteries in the best condition, leave the handset off 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. New batteries are available from the BT Synergy 4100 Helpline on 0870 605 8047. For instructions on how to install new batteries, see page 75.

After charging your handset for the first time, subsequent charging time is about 6–8 hours a day. Batteries and handset may become warm during charging. This is normal.

If you experience any problems, please call the Helpline on 0870 605 8047 or email bt.helpdesk@suncorptech.com
