Power Management
The Mesa uses 1 or 2 Li-Ion rechargeable battery packs.
CAUTION:
Only use batteries designed for the Mesa from an
approved vendor. Use of non-approved batteries may void your
product warranty.
Battery Life
Battery life on a full charge is generally up to eight hours per
pack (this can vary significantly depending on the application,
backlight usage, and radio usage).
Battery packs last approximately 300-500 charging cycles. This
is impacted by the use conditions, environment, etc.
Charging Battery Packs
To charge battery packs, refer to the instructions in Chapter 1,
Getting Started. It typically takes 2 to 3 hours to fully charge 1
battery pack and 4 to 6 hours to charge 2 battery packs.
We recommend that you keep the Mesa battery pack(s)
charging when they are not in use for up to two weeks. When
you plug the Mesa into the wall charger that comes with the
Mesa or the optional Travel Charger, the batteries are prevented
from being overcharged.
Mesa Li-Ion battery packs are charged most efficiently at
room temperature (68°F or 20°C). Only charge battery packs in
temperatures between 32°F and 104°F (0°C and 40°C).
CAUTION:
The Mesa is not totally sealed against water and
dust when battery doors are not installed and properly latched.
