QLn320 Technology
The QLn320 uses several technologies made popular in oth-
er Zebra Mobile Printer product lines.
Smart Battery
The QLn320 battery pack is a high capacity, smart Lithium Ion bat-
tery that contains electronics which allow the printer to monitor its
operating parameters. Among these are the number of charge cycles
it has undergone and its date of manufacture. Using these parameters,
the QLn320’s software can monitor the battery’s condition and alert
the user when to recharge or remove the battery from service.

The QLn320 printer will only function properly with genuine Zebra
smart battery packs.
The smart battery’s health has three states: GOOD, REPLACE, and
POOR. The battery health factor determines whether or not the print-
er can operate and what is communicated to the user via the display.
