Batteries deteriorate continuously at various rates from the time they are manufactured. Storage temperature is an important deterioration factor for all types of batteries. The cooler a battery is kept, the slower it will deteriorate, as long as its temperature remains above freezing. Damaging changes can occur in some types of batteries below freezing, so generally batteries should not be stored in a freezer or otherwise in freezing temperatures.

Low battery indicators

The Battery Pack icon on the status line of the handset display provides a visual indication of the amount of charge that remains in the Battery Pack. When the icon shows empty, if the handset is in standby mode, you hear a brief, modulated-ring signal, and the Battery Low message appears. The handset cannot be used until it is charged. If you are in a call you hear soft beeps, first slow and then fast, until the handset is unusable. When you first hear the beeps, you have two minutes to end the call or change the Battery Pack.
