The UCLI72-4 Quad Charger has a safety feature which
stops charging a battery after six hours regardless of its
charge state.
Battery Safety
Avoid accidental short circuiting of any battery. Allowing
battery terminals to contact conductive material will create a
short circuit which could cause burns and other injuries or could
start a fire.
Use of any charger not approved specifically by Zebra for use
with its batteries could cause damage to the battery pack or
the printer and will void the warranty.
Charger Safety
Use care in locating the Quad Charger. Do not place it in
locations where liquids or metallic objects may be dropped
into the charging bays. Do not block the ventilating slots on the
top and bottom covers. Ensure that the Charger is plugged into
a power source which won’t accidently be turned off if you will
be charging batteries overnight.
