Pure Lead Plus with MSE Technology

The only plate in the industry made entirely out of pure lead

  • ___
  • Pure Lead Plus with MSE Technology combines pure lead raw materials with innovative manufacturing techniques to create a battery with the energy density and performance of a VRLA and the longevity and reliability of a VLA battery. First introduced by C&D in 2004 with the msEndur™, MSE technology has been a key component of C&D’s product dependability and performance and over time evolving to be known at MSE Pure Lead Plus Technology.

    • All pure lead components, not just the grid
    • Low float current without a catalyst
    • Longer battery life
    • Up to 24-month shelf life
    • High temperature stability
    • Lower total cost of ownership

MSE Pure Lead Plus is a standard feature in msEndurII, Liberty MSE, High Rate Max PLP, TEL High Temp and Broadband AGM PLP product families.

C&D has been a pioneer of pure lead grid technology in VRLA batteries, introducing the HD series with a pure lead grid over 25 years ago. Where most “Pure Lead” batteries on the marketplace offer a pure lead, high purity grid or thin plate pure lead, PLP with MSE Technology uses both an ultra-high purity and tightly controlled active materials made from pure, virgin, lead. High purity grids improve the battery’s resistance to corrosion by eliminating grain boundaries within the grid where corrosion can form, and pure lead active materials allows C&D to closely monitor and control the grain size and purity reducing the side reactions that can cause corrosion in the first place.

PLP with MSE Technology uses a proprietary Ball Mill Oxide made with ultra-high purity positive and negative active materials in addition to specialized processing techniques to create a better-balanced cell  that operates with reduced float current similar to a flooded cell. This  slows grid corrosion and limits water loss typically associated with traditional VRLA batteries.  Because PLP with MSE Technology does not rely on a catalyst to reduce float current or aid recombination, the performance benefits are realized throughout the entire life of the battery and a wide array of applications without the need to replace or add a catalyst.

C&D Ohmic Ring™

Maintenance made easy

  • ___
  • The C&D Ohmic Ring™ is a design feature of C&D Technologies’ VRLA battery terminals that gives battery maintenance technicians an easily accessible location to take voltage, conductance, resistance, impedance and connection resistance measurements without the need to remove connectors. This improved access helps to speed up taking these maintenance measurements, saving valuable time and money each quarter by allowing technicians to test more batteries each day.

    • Easier & faster maintenance saving costs
    • Consistent measurements improves system reliability

The C&D Ohmic Ring™ is a standard feature on all True Front Access™ monoblocs and msEndurII cells.

Battery maintenance plays a vital role in the reliability of any Stationary Reserve Power system. Completing this maintenance is often costly and the value of the data collected is highly dependent on how the measurements were taken. In many cases the data collected is not reliable. The C&D Ohmic Ring™ helps to solve both of these problems by speeding up battery maintenance and improving the consistency and quality of the maintenance measurements.

The probe location when taking a conductance, resistance or impedance measurements is critical to collecting usable data. Taking a measurement from a connector, cable lug, washer or bracket can significantly change result of that measurement. In lab testing, taking an Ohmic measurement from a bolt changed the measurement an average of 60% versus taking it directly from the post. Taking a reading from a connector changed the measurement by an average of 10%. This variability makes trending quarterly measurements very difficult and reduces the value of the data. The C&D Ohmic Ring™ offers technicians a consistent location to take their measurements directly from the post, making data more reliable and allowing customers to identify potential issues sooner.

C&D True Front Access™

Is your battery REALLY front access?

  • ___
  • C&D True Front Access™ products feature a patented Extrusion Fusion Weld technology that allows a direct weld from the battery plates to the front access terminal of each monobloc. This weld eliminates connectors and secondary welds while allowing the post to be molded directly into the case, eliminating secondary terminal sealing processes that can be inconsistent. The elimination of secondary welds and connectors means that C&D True Front Access terminals offer lower resistance than other products, improving discharge capability and efficiency.

    • Only battery on the market with direct weld front terminal
    • Unmatched accessibility to the terminal the top, side or bottom of each post
    • Safer maintenance
    • Over-sized terminals for faster maintenance and cooling

C&D True Front Access™ terminals are available across many C&D product lines including TEL Long Duration, TEL High Temperature, UPS High Rate Max, UPS Pure Lead Plus and Advanced Energy Storage (AES) models.

VRLA Batteries were introduced into stationary battery applications over 30 years ago and offer customers improved energy density, and footprint savings. Monoblocs further improved this footprint savings and with their widespread use, supplies have found new ways of reducing the space required for battery systems. One of these key innovations in this footprint savings was developing monobloc batteries with terminals that were more easily accessible from the front of a rack or cabinet. This design allowed a significantly reduced maintenance space between shelves in battery racks and improved technician safety by eliminating the need to reach over battery terminals to access connectors at the back of a shelf.

C&D Technologies took this innovation one step further with the introduction of its True Front Access designs for Telecom and UPS applications Other designs on the market rely on more traditional manufacturing techniques, placing the terminals through the top cover of the monobloc near the front of the battery. These designs only offer side or front access to the posts, often requiring specialized connectors or cables to access them.

AES Nano-Carbon Technology

Enhanced for a longer life

  • ___
  • C&D’s Advanced Energy Storage (AES) VRLA products uses a high surface area nano-carbon blended specifically for C&D to enhance the negative active material. Nano-scale additives provide up to 100x more nucleation sites for the formation of lead-sulfate during a discharge, allowing the negative plate active material to be maintained and recovered, even after a deep discharge. Because C&D blends our own active material, we can introduce other proprietary additives to aid in high temperature stability and maintain surface area of the plates. This high-tech recipe means that AES battery models can maintain predictable, reliable capacity even after years in service and thousands of cycles.

    • Superior cycle life in renewable energy and other frequent cycle applications.
    • Partial state-of-charge Operation
    • More than 3000 Cycles at 50% DoD
    • Increased recharge efficiency
    • Decreased grid corrosion
    • More than 5000 Cycles from 80-50% SoC

AES Nano-Carbon Technology is specific to the AES product line.

While lead-acid batteries have been used in frequent cycle applications for decades, they are not ideally suited for applications where reliable power is not available. Traditional lead-acid type batteries in these applications suffer from one major drawback; they must be fully recharged after every cycle. When they are not brought back to full state of charge following each cycle, sulfation of the negative plate lead to premature failure of the cell. In renewable energy applications where power is only available in certain conditions, this means a generator or grid power must be available to recharge the battery system.

The development of lead-carbon batteries introduced a new solution for these applications that operates as easily and as safely as a traditional lead-acid battery, but with the new ability to operate in Partial State of Charge. The addition of carbon into the negative electrode stabilizes prevents the damage caused by not reaching full state of charge in traditional lead-acid designs. This allows users to charge only when power is available without fear of reducing battery life. An added benefit of operating in partial state of charge means that battery recharge can be stopped before it becomes inefficient at 90% state of charge. Eliminating the inefficient portion of the recharge both reduces the amount of power lost to heat generation and significantly reduces the amount of corrosion generated on the grid; thereby increasing the reliability of the battery as it reaches later stages of life.

Built on C&D’s field-proven DCS Technology, AES products can stand up to repeated daily discharges and even operate in Partial State of Charge (PSoC). This ability allows users to operate their systems at peak efficiency, eliminating wasted energy due to inefficient battery charging. By operating within this ideal window, battery life is also extended.
