CYCLON battery Single Cells and Monoblocs
should be handled with care. Batteries are shipped
without individual cell terminal protection and there
is a risk of short circuit if not handled correctly.

Resealable safety valve
A 50-PSI vent lets gases escape, then automatically reseals, so there’s no
risk of excessive gas accumulation within the battery, or “dry out” failure
from repeated recharges.
Pure lead plates
Made from 99.99% pure lead, CYCLON® battery plates are extremely thin,
so they offer more surface area than conventional batteries –
and far more power.
AGM plate separator
High-purity acid is absorbed right into the Absorbed Glass Mat (AGM)
plate separators, so the CYCLON battery provides leak-proof operation
in any position.
Steel can enclosure
The CYCLON battery’s metal outer jacket offers extreme shock, vibration,
temperature, and flammability protection.

Features and Benefits
Sealed pure-lead cells were invented by the Gates Corporation
in 1973. The purity of the materials used is key to supporting
the CYCLON® battery's performance benefits. A longer service
life, meaning fewer replacements and the cost associated with
it, combined with higher reliability and fewer system failures,
result in a lower long-term cost of ownership to the end user
or equipment owner.
What are the advantages of EnerSys® technology?
1. Power density - Per unit weight, the power provided by
pure lead products offers the greatest high-rate power
density for your energy budget. CYCLON® battery's
greater volumetric power allows engineers to consider
more energy-supporting features or design smaller,
lighter packages.
At high-rate and pulse discharges, EnerSys® CYCLON®
batteries offer the best performance value when
compared with competitive product in applications
at less than 100 minutes of discharge.
2. Cycle life - Compared to competitive lead products
(offering up to 200 full cycles), pure lead batteries provide
50% to 200% greater full cycle capability. CYCLON®
batteries will deliver up to 300 cycles (100% DOD, C/5).
And, because CYCLON® batteries incorporate a high
vent-pressure design, EnerSys products experience
no “dry out” failure mode from repeated recharges.
3. Float life - Conventional sealed-lead batteries vary
greatly in specified standby life: from three to six years at
20°C, C/20. CYCLON® battery Single Cells, however, offer a
ten-year design life at 25°C, C/5, to 80% of rated capacity.
At 20°C, CYCLON® battery Single Cells offer a fifteen-year
design life.
4. High stable voltage delivery - The high stable voltage
delivery of a pure lead battery results from its low internal
resistance. The flat discharge voltage profile of our batteries,
similar to nickel cadmium, combined with our products'
low internal resistance, means our batteries are able to
discharge and recharge their power more quickly and
efficiently and offer greater application flexibility. The pure
lead construction also gives more watts-per-unit weight at
high discharge rates.
5. Safety - Since CYCLON® battery Single Cells and
Monoblocs emit minimal to no gassing under normal
charging conditions they are safe for installation in
offices, aircraft cabins, hospitals or any other environment
occupied by human beings. Underwriters Laboratories (UL)
recognises all CYCLON® cells and batteries as components.
6. Widest temperature range - Due to the products' strong
construction and high vent pressures, these cells will
maintain their performance and physical parameters in
extreme conditions. At high temperatures, the chemical
reaction in a battery that causes aging is accelerated.
Pure lead technology resists that chemical reaction more
effectively than alloyed lead, thus allowing a battery to
have a longer service life. At high temperatures, when
conventional lead batteries experience internal moisture
loss from venting and case side wall distention, the
CYCLON® Single Cell battery, with its steel can (jacket)
and 50psi vent, does not experience these life-
robbing conditions. CYCLON® batteries have twice the
delivered capacity of conventional sealed-lead batteries
at temperatures below -20°C, offering unparalleled
low-temperature performance.
Our batteries have thinner plates, and therefore greater
plate surface area than conventional sealed-lead, thick
plate batteries. As a result our batteries can reach a high
state of charge in fast-charging applications in one-fourth
the time of conventional, sealed-lead, thick-plate batteries.
This is 50% to 100% overall better performance for your
energy dollar.
7. Rugged construction - Due to their strong external
packaging and internal pure lead composition, EnerSys®
products can withstand not only extreme temperatures but
also harsh usage.
CYCLON® battery Single Cells are available housed in cases
constructed of UL 94V-0 flame retardant rated material.
The CYCLON® battery Single Cell itself is in a metal jacket
giving added flammability protection. CYCLON® batteries
are shock and vibration resistant, designed to offer higher
tolerance levels to meet demanding applications, including
those in commercial and outdoor applications. The
company's focus on battery-case integrity and high vent
pressure, coupled with pure lead's low grid-corrosion rate,
means CYCLON® battery cells and Monoblocs provide the
longest service life possible.

Each plastic Monobloc consists of Single Cell elements,
internally connected to provide a 4 or 6 volt unit.
Monoblocs or Single Cells can be connected in series
or parallel to achieve the required voltage or capacity.
Monoblocs and Single Cells are supplied with spade
terminals making electrical connections quick and easy.
Additionally, EnerSys® products offer the highest vent
pressure in the market. As a result, our batteries are
more resistant to venting and dryout from continuous
overcharge in standby applications.
8. Fastest recharge - EnerSys® pure lead chemistry
allows our batteries and cells to offer the highest
recharge efficiency of any sealed-lead battery on
the market. With pure lead, you can achieve a 95%
state of recharge in less than one hour - without loss
of capacity or electrolyte using conventional
constant-voltage charging techniques.
Flexible charging options are possible with CYCLON®
battery Single Cells and Monoblocs, as no current limit is
required when using a constant voltage charger.
9. Orientation/placement/transport - Due to the products'
mechanical design, CYCLON® batteries can be mounted
and operated in any position, an attractive feature for less
accessible areas.
CYCLON® battery Single Cells offer UL 94V-0 flame-
retardant packaging, thus allowing the mounting of
systems in sensitive areas and human environments. Plus,
the unique and flexible 2-volt CYCLON® battery Single
Cell allows you to design your system using an almost
infinite number of packaging/design configurations.
CYCLON® single cells and monoblocs are classified
as “non spillable batteries” and are excepted from
comprehensive hazardous packaging requirements.
When shipped from the point of manufacture the product
complies with the relevant requirements of IATA and 49
CFR 173.159(d), specifically CYCLON® product has been
tested and found to comply with IATA Packing instruction
806 and Special Provision A67. As such CYCLON®
product does not have an assigned UN number and is not
required to be shipped under a proper shipping name.
The pure lead advantage
6Publication No: EN-CYC-SG-004 - June 2014
www.enersys-emea.com
CYCLON® battery Single Cells and Monoblocs have been
tested and determined to be in compliance with the
vibration and pressure differential tests contained in 49
CFR § 173.159(d).
Because CYCLON® battery Single Cells and Monoblocs
are classified as “Nonspillable” and meet the conditions
above, [from § 173.159(d)] they do not have an assigned
UN number nor do they require additional DOT hazard
labeling.
The regulation change effective September 1995, was to
clarify and distinguish to shippers and transporters, all
batteries that have been tested and determined to be in
compliance with the DOT Hazardous Material Regulations,
the International Civil Aeronautics Organisation (ICAO), and
the International Air Transport Association (IATA) Packaging
Instruction 806 and Special Provision A67, and therefore
excepted from all other requirements of these regulations
and classified as a “nonspillable battery”.
10. Shelf life - Pure lead batteries have an extremely low
self-discharge rate, thus providing extended storage
capability while maintaining high state-of-charge levels for
dependable operation.
CYCLON® battery Single Cells and Monoblocs have a shelf
life more than two times that of conventional lead batteries.
To assure maximum reliability, EnerSys recommends that
all stored cells/batteries be recharged (boost charged) once
every 24 months or when the open circuit voltage drops
to 2.00 volts per cell, whichever occurs earlier. Inventory
should be checked more frequently if storage temperature
regularly exceeds 25°C.
When shipping CYCLON® product, all cells must be
protected against short circuit and the outer packaging
should be plainly and durably marked as “Non Spillable
or Non Spillable Battery”. This applies when product is
repackaged at other locations. It is recommended that
short circuit protection is continued to be applied when
storing and handling CYCLON® product.

Monoblocs (use graph up to 40°C for Monoblocs)
State of charge for CYCLON® Battery Single Cells & Monoblocs
Figure 5-2: CYCLON® Battery Storage Time Vs. Temperature
Charging recommendations:
Broadly speaking, a battery may be
recharged using either a constant voltage
(CV) charger or a constant current (CC)
charger, or a modification of either or
both of these.
The exact regime chosen generally
depends upon the time and economic
constraints imposed by the system.
Constant current charging is widely used
in cyclic applications where a recharge
must be accomplished in a relatively
short time period. Constant voltage
charging, where a single voltage level
is applied across the battery terminals,
is the most suitable method to recharge
CYCLON® batteries. Depending on the
CV charger's current limit, it is possible
to recharge these batteries from a 100%
discharged condition to better than 95%
state of charge in less than one hour,
using only the cyclic charge voltage.
Constant voltage charging
Constant voltage (CV) charging
should be within the following ranges:
Fast Chargers, Per cell:
2.40 to 2.45 volts @ 25°C
12 volts:
14.40 to 14.70 volts @ 25°C
(for a maximum of 16-20 hours)
In cyclic applications, where the battery
is being significantly discharged at a
frequency greater than once per week,
the charge voltage should be a nominal
value of 2.40 Volts per cell (VPC), but can
range between 2.35 VPC and 2.45 VPC
to maximise cycle life.
Float Chargers, Per cell:
2.27 to 2.35 volts @ 25°C
12 volts:
13.62 to 14.10 volts @ 25°C
Nominal float voltage is 2.27 VPC
at 25°C, but float voltage can range
between 2.25 VPC (@25°C) and 2.35
VPC (@25°C) depending on the details
of the application. Voltages nearer 2.35
VPC would be used in applications
which are float in nature, but could have
frequent discharges of significant Depth
of Discharge (DOD).
To avoid thermal runaway in warmer
temperatures, and to improve charge
acceptance in colder temperatures, the
charger voltage should be compensated
by approximately 3 millivolts per cell per
degree Centigrade variance from 25°C.
This is a negative coefficient, with the
voltage being lowered as the temperature
increases, and vice versa.

There is no need to limit the inrush current to the battery
during constant voltage charging. The low internal resistance
of EnerSys® CYCLON® battery Single Cells and Monoblocs
allows for large inrush current without damage.
Since not all of the charge returned is accepted to replenish
the electro-chemical potential, a good rule of thumb to use
is that the charge returned should be 105% to 110% of the
capacity delivered on the previous discharge.
Most current waveforms are not pure DC nor are they pure
sine waves. Therefore, consult the EnerSys® Application
Support Department for assistance when evaluating the
charger current waveforms for your specific application.
A three-step 6-8 hour charge profile optimised for CYCLON®
cells and batteries is available on request from the Technical
Support Department of EnerSys®.

CYCLON® Battery 6V Monoblocs:
CYCLON® battery standard descriptions
CYCLON® battery cells are ideal for small ampere-hour
applications up to 25Ah. The sealed-lead construction
uses a starved-electrolyte system and a patented
grid-alloy providing numerous advantages.
Standard batteries are offered based on combinations of
the previously described CYCLON® battery cells and are
available in 6 and 12 volt configurations with capacities
ranging from 2.5Ah to 25Ah.
Battery Packages
Rigid plastic cases or shrink wrap packaging are available.
Rigid Plastic
Cases are available for most designs in either flame-retardant
ABS material, meeting UL 94V-0 flammability rating, or
Styrene (available only in 2X3 D and X battery configurations).
