All CYCLON
®
 cells and batteries are packaged, marked, 
labeled, and documented according to the appropriate 
transportation regulations when shipped from an EnerSys
®
facility. A shipper that fails to follow these same requirements 
may be subject to substantial civil and/or criminal penalties 
and may cause a safety hazard. 
All CYCLON battery packages must be capable of 
passing International Safe Transit Association (ISTA) 
Procedure 1A testing. 
Packages weighing no more than 20 lbs. must be 
packaged in a minimum 200 lb. burst strength or 32 
ECT certified carton. 
Packages weighing over than 20 lbs. must be packaged in 
a minimum 275 lb. burst strength or 44 ECT certified carton. 
No individual package can exceed a total gross weight 
of 70 lbs. 
It is the responsibility of the shipper to ensure each employee 
who directly affects hazardous material/dangerous goods 
transportation safety is appropriately trained in accordance 
with the selected mode of transportation. 
The terminals of CYCLON battery cells can cause shorts 
if they are not insulated during shipping. Protective caps 
or other durable inert material must be used to insulate 
each terminal of each cell unless cells are shipping in the 
original packaging from EnerSys in full box quantities. 
Protective caps are available for all cell sizes by 
contacting EnerSys Customer Service at 1-800-964-2837. 
International customers should call 1-660-429-6437. 
Assembled batteries must have short circuit protection during 
shipping. Exposed terminals, connectors, or lead wires must 
be insulated with a durable inert material to prevent exposure 
during shipping. 
FAILURE TO COMPLY WITH THESE REQUIREMENTS CAN 
CAUSE A FIRE DURING SHIPPING AND HANDLING!
1.10 UL Component Recognition 
All CYCLON batteries are recognised as UL components. 
2.1 Single Cell Construction
Both the positive and negative plates are made of pure lead-
tin and are extremely thin. The plates are pasted with lead 
oxides, separated by an absorbing glass mat separator and 
spirally wound to form the basic element. Lead busbars are 
then welded to the exposed positive and negative plate tabs. 
The external spade terminals on CYCLON battery 
single cells are inserted through the polypropylene inner top 
and are effectively sealed by expansion into the lead busbars. 
The element is then stuffed into the jar liner and the inner top 
and liner are bonded together. At this state of construction, 
the cell is sealed except for the open vent hole. 
A unique vacuum fill process then adds sulphuric acid and 
the Bunsen relief valve is placed over the vent hole. In the 
manufacture of a single cell, the sealed element is then 
inserted into the metal can, an outer plastic top added and 
crimping completes the assembly. The metal case is for 
mechanical strength and is the principal factor contributing to 
the high pressure rating of the resealable vent. The cell is now 
charged for the first time (electrochemically formed).
2.2 Monobloc Construction 
The monobloc construction differs from single cell 
construction as it is essentially a battery consisting of multiple 
cells, each cell element inserted in a single plastic container. 
Spade terminals are inserted into the molded openings 
connecting internally to the plate tab lead busbars. Intercell 
plate tabs are connected by through-the-wall welds. Acid is 
added using the vacuum fill process, the cover is heat sealed 
in place and a Bunsen relief valve installed. 
The battery is now formation charged. 
3.1 Introduction 
This chapter is devoted to describing specific performance 
characteristics of CYCLON batteries that make them 
a superior battery choice, particularly for demanding 
applications such as temperature extremes typically 
encountered in outdoor environments.
3.2 High Discharge Current 
CYCLON battery cells can be discharged at very high 
currents while maintaining a reasonably flat voltage profile. 
This characteristic is achieved because of the high plate 
surface area and closeness of the plates to each other due to 
the use of thin plates in a spirally wound construction. 
Typical maximum current capabilities of single cells and 
monoblocs are shown in Table 3-1 below. In all cases, the 
duration of discharge is one (1) minute to 1.50 volts per cell at 
an ambient temperature of 25°C (77°F).
