QLn Series User Guide
QLn Series Technology
The QLn320 and QLn220 use several technologies made 
popular in other Zebra Mobile Printer product lines.
Smart Battery
The QLn Series battery pack is a high capacity, smart 
Lithium Ion battery 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 printer’s software 
can monitor the battery’s condition and alert the user when to 
recharge or remove the battery from service.

 The QLn Series printers 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.
