QL Plus Series User Guide
The LI72 is a wall mounted fast charger with universal 110
to 230, 50-60 Hz. VAC input. Multiple A.C. plug configurations
comply with most international standards. This charger is in-
tended for use with Lithium Ion (Li-ion) batteries. QL series
printers only utilize Li-ion batteries.
Two three-wire versions of the LI72 are offered as illustrated
in Figure 4. The enhanced 3-Wire version (AT18737-x) offers
improved charging features and will replace the LI72 3-Wire
charger (AT17696-x).
Both of the LI72 models will charge a battery pack as fast as
its charge level will allow, and then switch over to a mainte-
nance charge to keep the charge at its maximum.
