Quick Charge NPEXU - Manual (Page 4)

OTHER SAFETY INFORMATION
Do not use charger if it shows signs of physical stress, or if DC
output leads or connector feel hot when used.
Do not disconnect the DC output clamps, or connector from the
batteries when the charger is on. The resulting arcing could cause
the batteries to explode.
Do not expose charger to rain.
NEVER charge a battery at a higher voltage than what it is rated
for.
The charger will become hot during use, provide adequate air flow
around it. Do not place charger on cloth or vinyl seats, blankets, or
around any other obstructive materials. Do not place charger
against walls, allow 12” of space on all sides.
BATTERY SAFETY & CARE INFORMATION
Always wear protective eye shields and clothing when working
with batteries. Batteries contain acids which can cause bodily
harm. Do not put wrenches or other metal objects across the
battery terminal or battery top. Arcing or explosion of the battery
can result. Do not wear jewelry when working around batteries.
Arcing can cause severe burns.
The tops of the batteries and battery hold downs must be kept clean
and dry at all times to prevent excessive self discharge and flow of
current between the battery post and frame.
With wet cell batteries, maintain the proper electrolyte level by
adding water when necessary. Never allow the electrolyte level to
fall below the top of the battery plates. Electrolyte levels fall
during discharge and rise during charging. Therefore, to prevent
the overflow of electrolyte when charging, add water only after
the batteries have been fully charged, or just enough to cover
the plates if discharged. Old batteries require more frequent
additions of water than do new batteries.
