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.
