4.0 BATTERY STORAGE BEFORE INSTALLATION
4.1 General
Batteries should be unpacked, installed and charged as soon as possible after receipt.
However, if this is impractical, follow the instructions below for storing the battery before
installation.
Store batteries indoors in a clean, dry and cool location. Storage at higher temperatures will
result in accelerated rates of self-discharge and possible deterioration of battery performance
and life.
Do NOT stack pallets. DAMAGE MAY OCCUR AND THE WARRANTY WILL BE VOIDED.
4.2
Storage Interval
Do NOT store flooded batteries longer than the following intervals without giving periodic
freshening charges. Under higher temperature conditions, greater charging frequency may be
required. Use date of battery shipment to determine freshening charge requirements.
•
Lead Antimony
—
every three months
•
Lead Calcium
—
every six months
Storage times exceeding the above may result in plate sulfation, which may adversely affect
electrical performance and expected life.
Give the battery a
freshening charge
before the end of the recommended storage interval. See
Section 8 for charging information.
Repeat the
freshening charge
for each additional storage interval until the battery is installed.
Maximum total storage time before installation is two years from date of shipment from the
factory to the customer.
Freshening charges
are required a minimum of every three to six
months during the storage time period, as noted above.
4.3 Advance
Preparation
If freshening time interval is likely to be exceeded in storage, make advance preparation to have
an adequate charger available and adjacent to an appropriate AC supply voltage. Positioning of
the cells to accept the temporary intercell connectors is another consideration of advance
planning. Keep cells on styrofoam pads until they are installed on the rack.
Make every effort to get the battery installed and connected to the charger before the expiration
of the storage period, thereby avoiding the additional labor cost of preliminary freshening
charges.
WARNING
FAILURE TO CHARGE AS NOTED VOIDS THE BATTERY’S WARRANTY.
