If extended storage is necessary, the battery should
be charged at regular intervals until installation can be
completed and float charging can be initiated. When in
extended storage, it is advised to mark the battery pallets with
the date of shipment and the date of every charge. If the
battery is stored at 77°F (25°C) or below, the battery should
be given its initial charge (refer to Section 11) within 6 months
of the date of shipment and receive a freshening charge
(perform per Section 11 Initial Charge) at 6 month intervals
thereafter.
