TPNA-1000 - Section I: The Basics
Battery Charging
The TPNA-1000 has a built-in 14.8 V / 2.1 AH Lithium battery. When fully charged, it can typically
be used for six hours. When the battery charge drops below 13.5 V, the battery symbol flashes in
the display screen. If the charge drops below 13 V, the TPNA-1000 shuts off automatically to
protect the battery. You cannot turn the TPNA-1000 on again until you recharge the battery.
Batteries that do not hold their normal five-six hour charge may
need replacement. Contact Trilithic customer service for
replacement batteries.
The batteries should only be charged when the ambient
temperature is between 10° C and 35° C. Failure to do so could
shorten the battery life.
The battery MUST be charged with the Trilithic charger supplied
with the TPNA-1000. Using any other charger may cause
damage to the battery or instrument.
To charge the TPNA-1000’s battery, connect the battery charger to the power input on the right
side of the TPNA-1000 and plug the charger into an AC outlet.
While charging, the charge indicator on the front panel of the TPNA-1000 will be red. A full charge
will be achieved in approximately five hours, and will be indicated as such by a green charge
indicator located on the front panel to the right of the POWER button.
The charging status may be observed by turning the TPNA-1000 On and then Off while the
charger is connected. The charging display will indicate the approximate percentage of charge
and the elapsed charging time.
The TPNA-1000 can be operated while the batteries are charging.
