Quick Charge QPA12v/50A - Manual (Page 2)

New batteries will not deliver their full performance until after several cycles.
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.
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 DO NOT OVERFILL. Old batteries require more frequent additions of water than do new batteries.
Do not over discharge the batteries. Excessive discharge can cause polarity reversal of individual cells resulting
in complete battery failure.
Provide adequate ventilation for the batteries and charger. Do not obstruct the flow of cooling air around the
charger. Provide at least 1" of space around charger. Do not allow clothing, blankets or other material to cover
the charger.
WARNING: Chargers can ignite flammable materials and vapors. Do not use near fuels, grain, dust,
solvents, or other flammables.
CAUTION: Before connecting the charger to the batteries, make sure the battery pack is of the same
voltage rating of the charger.
