It takes approximately 4.5 hours to recharge a fully de- pleted battery pack regardless of the system power state.

NOTE

Through normal use, the capacity of a battery pack will gradually decline. Should you notice that the battery does not stay charged as long as ex- pected, it is probably necessary to replace the bat- tery with a new one. Please refer to the section “Battery Replacement” in this chapter. A battery pack should recharge approximately 300 times dur- ing the life of the battery.

Battery Replacement

Note the following when replacing batteries:

If the main battery becomes weak, the MobilePro auto- matically turns off. Recharge or replace the main battery

Timmediately if the power goes off.

When replacing the back-up battery, always use a CR2032 battery.

!WARNING

Only use a CR2032 battery as your back-up battery. Installing another battery type can result in an ex- plosion or fire.

See “Battery Precautions” later in this chapter, for

Tmore battery handling information.

If you fail to replace a depleted main battery for an ex- tended period of time and the back-up battery is weak, the contents of the MobilePro memory may be lost.
