Chapter 2 Standard Features 15
Battery packs are charged most efciently at room
temperature (68°F or 20°C). They will not charge if it is too
hot or too cold.
We recommend that you keep the Mesa 3 battery pack(s)
charging when it is not in use for up to two weeks. When you
plug the tablet into the wall charger that comes with it, the
batteries are prevented from being overcharged.
Battery Life
Battery life on a full charge can be 20 hours or more. This
varies depending on whether or not you also have an
optional internal battery, the applications used, backlight
usage, and radio usage. The optional internal battery adds
5-6 extra hours of battery life.
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.
CAUTION: Only use batteries designed for the Mesa 3 from
an approved vendor. Use of non-approved batteries may
void your product warranty. The Mesa 3 must be returned to
the factory for replacement of the optional internal battery,
although the internal battery pack is designed to last the
life of the tablet.
Power States
The Mesa 3 runs on battery power, or external power. If
external power is used, a replaceable and/or internal
battery must be installed.
CAUTION: The unit is not designed to run on external power
without a battery installed. Doing so can damage internal
components of your unit and void the warranty.
