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.
The LI72 is supplied in two variations: a two wire version
and a three-wire version. The three-wire version offers more
intelligent charging features and is used with more-recently
produced printers..
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.
Charging Battery Packs with the LI72 Two-Wire Version
Plug the LI72 into the appropriate A.C. wall receptacle, and
then insert the charge cable into the battery pack charger jack.
The charge indicator LED will indicate the status of the char-
ger as follows:

The battery may have an
internal short, or its charge
monitoring circuitry may be
malfunctioning. The battery
pack should not be used any
further.
Do not charge batteries with the two-wire LI72 model while printing.
Attempting to print while charging can result in improperly charged
batteries.
Caution • Do not leave the two-wire charger plugged into a battery
pack for a prolonged period of time when it is installed in the printer
and has reached the maintenance charge state. Charging a battery
when installed in a printer for a prolonged period of time could cause
damage to the printer.
