The model 2500THS printers require an adaptor output of 10VDC/1.4A.
The battery Fast-charge is initiated each time the power adapter is
connected to the printer
The fast-charge controller checks the battery's voltage and temperature,
before the start of the fast recharge process. If the battery voltage or the
temperature is outside of the fast-charge limits, the charger defaults to
trickle charge at C/10 or 70mA rate
Optional external battery chargers are available for Extech batteries

4.3 Verifying Battery Charge State:
It is strongly recommended testing your printer before returning to Extech. Follow
these steps to identify and correct any battery power problem that may be
encountered. These will help to identify that the fault is with the printer and not
some other part of your system.
To test the AC adaptor use a multi-meter and measure the output. Output
should be 10VDC
Press the <ON/OFF> switch and wait until all LED's are off
Insert the AC adaptor plug into the printer. If the amber LED goes on, the
battery is not fully charged but the charge circuit is functioning.
