- Sealed pure-lead cells were invented by the Gates Corporation in 1973. The purity of the materials used is key to supporting this lead-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 th the end user or equipment owner.
- What are the advantages of HEPI technology?
- Power Density — Per unit weight, the power provided by pure lead products offers the greatest high-rate power density for your energy dollar. Cyclon’s greater volumetric power allows engineers to consider more energy-supporting features or design smaller lighter packages.
At high-rate and pulse discharges, HEPI’s Cyclon products offer the best performance value when compared with competitive product in applications at less than 100 minutes of discharge.
Cycle Life — Compared to competitive lead products (offering up to 200 cycles), pure lead batteries provide 50% to 200% greater full cycle capability. Cyclon product (excluding the present BC design), will deliver more than 300 cycles (100% DOD, c/5). And, because Cyclon incorporates a high vent-pressure design, HEPI’s products experience no “dry out” failure mode repeated recharges.
- Float Life — Conventional sealed-lead batteries vary greatly in specified standby life: from three to six years at 20° C, C/20. Cyclon, however, offers an eight-year design life at 25° C, C/5, to 80% of rated capacity. At 20° C, Cyclon single cells offer a ten year design life.
- 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 construction also gives more watts-per-unit weight at high discharge rates.
- Widest Temperature Range — Due to the product’s strong construction and high vent pressure, 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 these life-robbing conditions. Cyclon has 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.
- Rugged Construction — Due to their strong external packaging and internal pure lead composition, HEPI’s products can withstand not only extreme temperatures but also harsh usage. Cyclon Single Cell external cases are constructed from V0 flame-rated materials. Cyclon products 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 cells and Monoblocs provide the longest service life possible.
Each plastic Monobloc consists of Single Cell elements, internally connected to provide a 4 to 6 volt unit. Monoblocs or Single Cells c an 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, HEPI 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.
- Fastest Recharge — HEPI’s 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% safe 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 and Monobloc, as no current limit is required when using a constant voltage charger.
- Orientation/Placement/Transport — Due to the products’ mechanical design, Cyclon can be mounted and operated in any position, an attractive feature for less accessible areas.
Cyclon Single Cells offer V0 flame-retardant packaging, thus allowing the mounting of systems in sensitive areas and human environments. Plus, the unique and flexible 2-volt Cyclon cell allows you to design your system using an almost infinite number of packaging/design configurations.
Since Cyclon is covered under the US Department of Transportation (USDOT) unregulated “nonspillable wet electric storage batteries” classification and International Air Transport Association (IATA) “unrestricted” air shipment categories, shipping is easy, and worry free.
- 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 Single Cell and Monoblocs have a shelf life more than two times that of conventional lead batteries. To assure maximum reliability, HEPI 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.
