Battery Status and Management
Battery icons on the Status bar shows the status of installed
batteries. The large battery icon represents the removable
battery while a smaller battery icon represents an optional
internal battery. The status of these icons follows:
If both the internal and the removable batteries are
„
installed, a bigger battery icon and a smaller battery
icon are shown.
If a removable battery is not present, both battery
„
icons are shown, but the larger battery icon has an
exclamation mark signifying that it is not present.
If only the removable battery is present, only the large
„
battery icon is shown.
Charging the Battery Pack(s)
For tablets that have both a removable battery pack and
an optional internal battery pack, the intelligent internal
battery charging circuit first charges the battery pack with
the least amount of energy. When this battery pack comes
to the same level as the other battery pack, then both
battery packs are charged at the same time until they are
both fully charged.
Battery packs are charged most efficiently at room
temperature (68°F or 20°C). They will not charge if it is too
hot or too cold.
Battery Life
Battery life on a full charge is about 12 hours for the
removable battery and an additional 5-6 hours for the
optional internal battery. Battery life varies depending on
the applications used, backlight usage, and radio usage.
The shelf life for battery packs is about one year. The battery
packs should be recharged at least once per year. This
prevents the battery packs from discharging to a level that
might damage the batteries. Battery packs that are not
recharged at least every year could fail to work or may
have reduced capacity. Battery packs typically last 1,000 to
3,000 charging cycles.
