Quick Charge Multi Bank - Manual (Page 5)

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.
Do not over discharge batteries. Excessive discharge can cause
polarity reversal of individual cells resulting in complete battery
failure. Re-charge batteries as soon as possible after a deep
discharge, but not if they are warm, allow a cooling down period.
Provide adequate ventilation when charging batteries. Chargers can
ignite flammable materials and vapors. Do not use near fuels,
grain, dust, solvents, or other flammables.
Do not charge batteries in excessively hot temperatures; wait till
the cool of the evening.
PRE CHARGE INFORMATION:
Mount the charger in the desired location. Allow space for the
charger to dissipate heat, it will get hot while in use. Do not seal
the charger in an air tight compartment. Do not cover the charger
with any material.
Make sure the AC cord, DC output leads, terminals,
connectors, or clamps are all in good working condition. Do not
use the charger if there are any signs of stress or damage, or if
wires are cut or have damaged insulation. Using this charger with
any of these symptoms could result in a fire, property damage, or
personal injury. Have a qualified service person make the
necessary repairs. Repairs should not be made by people who are
not qualified.
