All cordless phone batteries wear out over time and eventually you will experience less and less talk time between charging, that is the time to replace the batteries.

When replacing your BT8500 cordless phone batteries please check you insert them correctly and then charge them for a minimum of 24 hours the very first time.

Running the batteries down every few weeks will help them last as long as possible.
