Important Notes On Replacing Batteries; Verifying Battery Charge State - Datamax APEX 2 User Manual


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 exceeds the fast-
charge limits, the charger defaults to trickle charge at C/10 or 70mA rate.

Optional external battery chargers are available for Datamax-O'Neil batteries. Refer to
Section 4.7 "Printer Supplies" for detailed information.


new battery.
Risk of explosion if battery is replaced by an incorrect type.
Follow instructions in Section 4.5 to dispose of used batteries.

4.3 Verifying Battery Charge State

It is strongly recommended that the printer be tested before it is returned to Datamax-O'Neil.
Follow these steps to identify and correct any battery power problem. These steps will help
determine if the fault is with the printer or with some other part of the system.
To test the AC adapter:

Use a multimeter and measure the output voltage. The output should be 10VDC.

Press the <ON/OFF> switch and wait until all LEDs are off.

Insert the AC adapter plug into the printer. If the amber LED switches on, the battery is
not fully charged, however the charge circuit is functioning correctly.

The AC power portion of the circuit appears OK.
To test the DC power:

Disconnect the AC Adapter after the battery has been allowed to charge for approx. 5
minutes.

Press and hold the <FEED> switch, press and release the <ON/OFF> switch and then
release the <FEED> switch. The printer will print a "self test" receipt.

If the self test receipt is printed, the DC power is OK.
To test if the battery is accepting charge:

Press the <ON/OFF> switch and wait until all LED's are off.

Plug the AC power adapter into the printer. Press <ON>; the green LED will illuminate and
switch off after approx. 20 seconds.
