by Darren Murph posted Nov 9th 2009 at 11:22AM

It’s rare if a month flies by without some random university or DIYer proclaiming that the next major jump in battery technology is just over the horizon, and yet, here we are — in the year 2009 — still buying overpriced AA cells from Duracell and Energizer that deplete far too quickly given the technology available. Heck, even those standard rechargeable cells have seen their performance degrade hastily in our experiences, and we’ve been longing for a rechargeable cell that was actually worth its salt for a long, long time. Frankly, we passed off the PowerGenix NiZn battery as just another slice of vaporware when it was first uncovered in late 2008, but after they went on sale this summer, we decided to really put a set through the paces. Click on to find out how we feel about ‘em after months and months of hardcore usage.

One of the major concerns with traditional NiMh rechargeables is just how weak they are, and just how quickly their longevity declines. With few exceptions, most of these cells can’t actually power a dedicated hotshoe flash for more than a few minutes (if at all), and any application that demands a serious amount of power generally asks too much from these pricey tubes. Furthermore, these batteries also have a tendency to go from fully charged to empty faster and faster as time goes on, and while we understand that said phenomenon is simply a harsh reality when dealing with devices such as this, we always felt that the performance decline was unacceptable given the price premium attached to ‘em.

Enter PowerGenix, a little known company with a lot of hustle and a pocket full of promises. The company is selling 1.6v AA Nickel Zinc rechargeables at a variety of outlets now, with the MRSP for a 4-pack sitting at $14.99; the special charger (needed for charging NiZn batteries) can be purchased along with four cells for $24.99. We began using these with exceptionally low expectations, and six wedding shoots later, we’re now grinning from ear to ear. Our Nikon Speedlight SB-600 chews through standard batteries like a voracious beast, only squeezing out around 200 to 300 shots on a warm, lucky day. The PowerGenix cells, however, allowed us to fire the flash anywhere between 300 and 400 times in all conditions, and even after running them bone dry and juicing them back up for months on end, we’ve yet to see ‘em take a performance hit.

Performance advantages of NiZn battery demonstrate need for mWh—a new measure of battery capacity

Challenge: The Need for a New Measure of Battery Capacity

Rechargeable batteries were first commercialized in the mid-1960s and have since undergone numerous technological advances. Unfortunately, the way in which battery capacity is measured—typically in amp hours (ah) or milliamp hours (mAh)—has not evolved to keep pace with the introduction of new technologies.

The mAh rating is a product of a battery’s current and time rating, omitting an essential element of battery power and capacity: voltage. mAh served as a valuable measurement gauge of battery performance when all batteries provided equal or similar voltage. However, an alternate measurement called milliwatt hour (mWh), which multiplies mAh by voltage, delivers the more informative and precise measurement needed to analyze and compare today’s differentiated battery market. The mWh specification can help businesses and consumers understand the true capacity of batteries to provide energy to a load.

Limitations of mAh

Today, batteries and battery packs are commonly described based on two separate characteristics: voltage and mAh (the product of current capacity over a finite time period). For example, an AA-cell Nickel-Cadmium (NiCd) battery may have a rated capacity of 800 mAh, and an open circuit voltage of 1.2 volts. These separate conventions have served the industry well when comparing batteries with similar chemical characteristics, but they are far less useful when comparing battery systems with dissimilar chemistry.

A significant limitation of the mAh designation becomes evident when mAh is used to compare two batteries with varying voltages, such as NiCd and Nickel-Zinc (NiZn) batteries. Because NiCd batteries have an open circuit voltage of 1.2 volts and NiZn batteries have an open circuit voltage of 1.6 volts, a NiCd cell rated at 800 mAh does not deliver the same performance as a NiZn cell rated at 800 mAh,. To compare and understand the performance capability of the two batteries, open circuit voltage must be factored into the measurement, which by definition the mAh specification does not do.

A better alternative: mWh

To detail more precisely the performance differences between batteries, the mAh rating—which is the product of current and time—must be enhanced to include voltage. As the product of current, time and voltage, the mWh rating delivers this much-needed measurement improvement.

Returning to the example of NiCd and NiZn cells that are each rated at 800 mAh, the mWh rating reveals the substantial performance difference between the two batteries. With an open circuit voltage of 1.2, the mWh rating of the NiCd cell would be 960 mWh (800mAh x 1.2v).  Comparatively, the NiZn cell would have a much higher rating of 1280 mWh (800mAh x 1.6v).

Yes, only by employing the mWh rating does it become evident that there is a significant capacity difference between NiCd and NiZn—a difference that is masked by the limitations of the mAh rating.

Solution: Practical Applications of the New mWh Specification

To demonstrate the many benefits of the mWh specification, we will examine a few common electronic equipment applications for which businesses and consumers depend on a thorough understanding of battery capacity and performance. 

Example 1: Digital Photography

Digital photographers want battery packs that provide a high number of total camera flashes with minimal reboot time between each shot. Using mAh, typical NiMH and NiZn battery packs appear nearly identical; only by implementing the mWh designation do the performance advantages of the NiZn battery packs become evident.

A typical NiMH battery pack may offer a digital camera user a total of 250 flashes before needing a recharge. The NiMH battery pack might be comprised of four AA-cell NiMH batteries with a rating of 800 mAh. A comparably sized NiZn battery pack (four AA cells) may also have a rating of 800 mAh rating, and yet the NiZn battery pack can achieve 400 digital camera flashes and lower reboot time throughout the cycle life.

Representational view of NiZn vs. NiMH discharge in a camera application

One reason for the performance difference between the two battery types is that digital cameras, like all electronic devices, have a minimum operating voltage that must be sustained to ensure successful operation. Because NiMH systems typically start at a significantly lower pack voltage than NiZn systems, the NiMH system will fall below the minimum operating voltage of the camera before its NiZn counterpart. Despite the fact that the NiMH battery pack may not have used the entire energy capacity of the pack, the minimum voltage cut-off of the device renders the additional capacity useless.

Because NiZn delivers greater mWh capacity it’s able to provide steady-state optimal performance over a larger portion of the system discharge. This correlates to not only more shots or flashes per charge, but also more responsive electronic performance. In the case of a digital camera this translates into quicker flash recharging and processor speed to allow for shorter recovery time between shots.

The bottom line is that battery pack voltage is not accounted for by the mAh rating convention. The four-cell NiMH battery pack in this example has a pack rating of 4.8 volts (4 x 1.2 volts/cell), compared to the 6.4-volt pack rating of the four-cell NiZn battery pack. This is a significant difference that affects user experience but is overlooked by the mAh rating—and would be accounted for by the new mWh rating.

Example 2: Flashlights

Flashlights provide another example of the variable performance possible between two batteries with identical mAh ratings. A two-cell AA battery system powers many conventional flashlights, and for the sake of this illustration, both the NiCd and NiZn systems have the same mAh rating of 800.

A consumer who purchases either a NiCd- or NiZn-powered flashlight would expect similar performance, based on the identical mAh rating. However, the flashlight with the NiZn cells will produce brighter light throughout the cycle life of the batteries. The flashlight with the NiCd batteries will produce a light that is not as strong, and the light will dim more over time.

Comparison of flashlights using NiCd vs. NiZn batteries

Again, the reason for the performance disparity is the NiCd battery pack’s rating of 2.4 volts, compared to the NiZn battery pack’s higher rating of 3.2 volts. Only by factoring in the battery pack voltage using the new mWh rating can a business or consumer understand the significant difference between the two types of cells.

Example 3: Power Tools

The value of the mWh rating becomes most evident when considering battery packs such as those commonly used in cordless power tools. A battery pack is a combination of cells, and voltage (rather than mAh) is commonly used to measure expected performance. As compared to voltage alone, the mWh rating provides a more meaningful and detailed way to describe, compare and analyze battery packs.

Assuming mAh capacity of 800 for both the NiCd and NiZn cells, a 19.2-volt NiCd battery pack would be rated at 15,369 mWh (16 cells x 960 mWh), while a NiZn pack would be rated at 15,360 mWh (12 cells x 1280 mWh). If a battery pack with a minimum capacity rating of 15,000 mWh were needed for a cordless tool application, the mWh measurement makes it evident that 16 NiCd cells (15,000/960) would be needed, compared to just 12 NiZn cells (15,000/1280).

Using voltage alone for battery packs might suggest that the performance between NiCd and NiZn cells would be nearly identical. In fact, because fewer cells are required, a NiZn pack is more reliable since fewer inter-cell connections are needed. In addition, the battery pack is smaller, weighs less and costs less—all while delivering equal or greater performance. Furthermore, the benefits of reduced size and pack complexity are amplified as the power requirements of a device increase, making the differentiation in performance measured by the mWh rating greater as battery pack size increases for devices such as in electric bikes and vehicles.

Performance gains as battery pack size increases

Conclusion: mWh Specification Offers Greater Clarity and Precision

For decades, the mAh rating has provided a helpful guide to the relative performance of different batteries, but today’s new technologies require a new battery specification that delivers more detailed and comprehensive information about battery capability and performance.

As shown above, the value of the mWh rating is particularly evident when considering batteries of different chemistries that have similar or identical mAh ratings, and yet deliver vastly different performance. The comparison between NiCd and NiZn cells is particularly revealing because their mAh ratings are often similar, and yet NiZn cells are technologically advanced, offering high energy density, superior power density, and longer cycle and shelf life, as well as being nontoxic and easily recyclable.

For businesses and consumers, information is power. By factoring in voltage as well as current and time, the mWh rating offers a superior alternative to mAh—one that provides all the information necessary to make smart, informed decisions about battery capability and performance.

Warranty is 1 year replacement -Free of Charge from Powergenix- San Diego, CA

We at DepotEco are adding something really exciting to our inventory this summer! We have the honor of being one of the first stores to offer the newest in innovative Nickel-Zinc (NiZn) battery technology from PowerGenix.

In the past few years, interest in PowerGenix NiZn batteries has skyrocketed as their reputation for producing the most reliable, highest quality NiZn technology has grown. Today the company is supplying NiZn cells into multiple markets including power tool, lawn and garden, consumer AA, military, and light electric vehicle (LEV).

In the exciting and quickly evolving world of Hybrid Electric Vehicles (HEVs), PowerGenix and their NiZn battery technology is being recognized as a game changer and real step forward in terms of efficiency, power, environmental soundness, and cost effectiveness. PowerGenix’s NiZn powered Toyota Prius was showcased at the 2009 San Diego International Auto Show where the advanced battery vehicle was featured in the Eco-Center, the main feature of the 2009 show. As the Prius, the Insight, and other new hybrid cars battle it out for the top spot, PowerGenix’s NiZn technology is finding itself at the center of HEV innovation.

PowerGenix has also entered into a supply agreement with PowerEagle, the leading manufacturer of electric bicycles in China. Under the agreement, PowerGenix will supply its NiZn cells for pack fabrication into the entire product line offered by Veloteq, PowerEagle’s North American sales and distribution partner, beginning in 2009. In many other arenas PowerGenix has seen a great increase in demand and investment and has accordingly begun high-volume manufacturing.

For decades NiZn batteries have been recognized for their usefulness in applications demanding high discharge rate capabilities. With a high energy-density ratio and an open circuit voltage of 1.6 volts they have been heralded as the batteries of the future for high drain applications. Now PowerGenix- an innovative San Diego based company founded in 2000- has developed and is manufacturing patented NiZn 1.6 Volt Rechargeable AA batteries that make NiZn technology more effective, useful and available than ever before.

PowerGenix has improved already efficient NiZn technology by increasing cycle-life, lowering cost, reducing size and weight by 30% and improving low temperature discharge behavior. The small size and low internal resistance of PowerGenix NiZn 1.6 Volt Rechargeable AA Batteries enables the delivery of significantly more power during periods of peak demand than a nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) battery of comparable size.

Another way that PowerGenix NiZn batteries have raised the bar is by their ability to completely recharge in less than two hours and achieve 80% recharge within one hour, a key benefit for cordless power tools, electronics and many other applications. These rechargeable batteries are also completely safe, non-combustible and easier on the environment than other comparable technologies.

Until now, NiZn 1.6 Volt Rechargeable AA batteries have been available only in limited quantities via one camera merchant. But we at DepotEco were so impressed by the efficiency and environmental soundness of these batteries that we were determined to make them available to our customers. We are honored to announce that beginning in late June we will be one of the first stores to carry these amazing batteries. They are now available online and in our brick and mortar store.

Coming Soon to a Hybrid Near You: NiZn Batteries

Combining the time-tested reliability and power of the internal combustion engine with the low-rev efficiency and emissions-free locomotion of an electric motor, hybrid vehicles have proven extremely popular with the American public.  New hybrids are almost immediately in high demand, and with gas prices continuing to climb upward, the interest seems unlikely to flag anytime soon.

However, there are many downsides to hybrid technology that negatively affect both vehicle performance and the pocketbook of the American consumer.  The weight  of the combined battery and engine makes hybrids heavier than comparable vehicles.  Existing battery chemistry can be very expensive to create, as it can contain a variety of rare metals. Disposal may increase the cost of ownership, too, due to the presence of highly toxic materials.  Plus, popular lithium-ion batteries have a nasty tendency to explode.

But now, PowerGenix, a battery company based in San Diego, has developed an impressive, relatively environmentally friendly solution to the unique problems presented by hybrid-electric vehicles: nickel-zinc batteries.  NiZn, with its 30% increases in capacity and power over existing batteries of  similar size, is ideally suited for high-power, low-drain applications, such as HEVs. The use of a zinc, which is quite cost effective at less than a dollar per pound, offers excellent price savings compared to lithium-ion and metal hydride batteries.  Reduced toxicity increases the ease of disposal, and the more stable battery chemistry eliminates the chances of an unexpected explosion.

NiZn power is not a new technology. Thomas Edison worked with NiZn during his career, and the technology has been used in transportation before, powering a few streetcars in Ireland during the 1930s and ’40s. Until recently, however, the Achilles’ heel of NiZn batteries had been their cycle life limitations.

But recent developments in the use of electrolyte additives have created NiZn batteries good through hundreds of cycles, making them a viable alternative to existing technology.  Additionally, PowerGenix’ NiZn cells operate at 1.5v, the same voltage of existing disposable batteries, making them an ideal and longer-lasting replacement for the billions of alkaline batteries in use worldwide.

Realizing the potential of the technology, PowerGenix planned ahead, designing its NiZn batteries to be readily produced using existing infrastructure. “Technology design from the get go was for production on existing nickel metal-hydride and nickel-cadmium lines”, says PowerGenix CEO Dan Squiller. And the move has paid off—through an overseas supplier, PowerGenix will be able to produce some 1.2 million cells each day.

Like any other technology, NiZn batteries are not a magic fix. Existing zinc mining operations do have significant environmental downsides, and nickel, though used in most existing rechargeable batteries, remains a expensive. Still, these issues not withstanding, nickel-zinc batteries represent an exciting new frontier for hybrid vehicle development.

Earlier this year, PowerGenix’s NiZn technology was certified by the RBRC for collection and recycling, becoming only the fifth rechargeable chemistry recognized by the program.  PowerGenix’s NiZn batteries contain no toxic heavy metals such as lead, cadmium or mercury and are the most recyclable rechargeable chemistry on the market.

Nickel and zinc are among the Earth’s most abundant elements, found virtually everywhere in our daily lives. These natural elements are found in the earth, in the food you eat and in a wide variety of products. Both elements are readily recyclable and many products on the market today come from these recycled supplies.

About Nickel

Nickel has many uses from construction materials to food preparation, but its many favorable characteristics make it an excellent choice in the use of high powered rechargeable batteries. For more information on nickel, its many uses and its metallurgical properties, visit the Nickel Institute.

Zinc Facts

Zinc’s unique properties allow it to be used in an array of products from cosmetics, to baby powder, to precision parts for automobiles, airplanes and appliances. The International Zinc Association notes that one of the most useful characteristics of zinc is its resistance to atmospheric corrosion. The ranking of zinc in the electromotive series of metals (an indication of a metal’s tendency to oxidize, or give up electrons) positioned below magnesium and aluminum but above cadmium, iron, nickel and hydrogen, make it an exceptional material to use in conjunction with nickel when designing a battery. The electronegative characteristics of zinc have made it a popular choice in a variety of primary (single use) battery technologies for many years.

Recyclability

More than 6.5 million metric tons of zinc slab, oxides, powders and dusts are consumed each year in the Western World, two million of which come from recycled zinc. In the United States, the Bureau of Mines estimates that with enhanced recovery, recycled zinc will ultimately account for more than 40% of the total amount of zinc used

Meanwhile, nickel’s resistance to corrosion means that when most nickel-containing products are eventually discarded, they are still intact and easily identifiable (e.g., a kitchen sink made of stainless steel). This aids in the collection and sorting of nickel-containing products for recycling.

Sustainability

While abundant, both nickel and zinc are finite resources. However, their innate characteristics and recyclability assure environmentally sensitive availability for long-term development. Unlike many other materials nickel and zinc can be recycled again and again while maintaining their physical and chemical properties. There remains the same amount of each element at the end of a particular product cycle as at the beginning.
