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 intended 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 maintenance charge to keep the charge at its maximum.

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.
