Our product line includes a selection of high-quality lead battery components—key to the global shift to EVs. Learn how lead batteries are driving the electric vehicles and infrastructure of the future.

    Why EVs Need Lead Batteries

    Did you know that there are lead batteries in EVs? High-voltage lithium batteries power the electric powertrain, while lead batteries power the low-voltage (12V) safety and auxiliary systems, such as those that drivers and passengers interact with directly. Here is an overview of the 12V capabilities and benefits of lead batteries that make them important in the shift to EVs.

    12V Capabilities

    Lead batteries perform numerous functions in 12V vehicle applications. These capabilities include:

    • While Driving — Lead batteries can power increasing electrical loads for accessories and supplement power for instances of peak load demand (e.g. power steering, seat heating).
    • Parked/Off — Lead batteries enable fob scanning and theft protection. Additionally, they allow for vehicle connectivity to GPS and to facilitate over-the-air updates.
    • Emergencies — Lead EV batteries power functional safety systems to get the vehicle off the road in the event of high-voltage failure of the propulsion system.

    Advantages of Advanced Lead Batteries

    Advanced lead batteries offer several benefits that make them ideal EV batteries, including:

    • Cost Competitiveness — The total cost of ownership is lower than you would find with other types of batteries.
    • Reliability — Advanced lead batteries offer decades of proven performance.
    • Supports the Shift to EV Ecosystems — AGM batteries, in particular, are invaluable for EV charging infrastructures and supporting the electric grid, with long lifespans, safe handling, high-power output, and increased stability that promote the transition to EV vehicles.
    • Sustainability — With a 98-100% recycling rate, advanced lead batteries are the sustainable option.
    • Safe Chemistry — There is no risk of thermal runaway with advanced lead batteries.

    Why Use Advanced Lead Batteries Like AGM?

    Compared to lithium-ion batteries, lead batteries offer advantages for 12V applications in electric vehicles. AGM and other advanced lead batteries enable the stop-start function that reduces vehicle emissions. AGM batteries are especially popular because of their flexibility for where they are mounted in the vehicle due to their non-spillable design, and there is no thermal runaway risk. Due to their robust design, AGM batteries can continue to function properly after a collision in most cases, whereas lithium batteries would require additional electronics to ensure functionality and safety.

    Lead batteries have well-established supply chains and are cost-effective, reliable, and sustainable. What makes lead batteries sustainable is their use of recycled materials. Disposed or end-of-life batteries can be recycled to produce new batteries, which have a low carbon footprint: around 15 kg CO2 per kWh. Reusing materials reduces costs and makes recycling lead batteries an easy way to support global sustainability efforts. The U.S. currently has a lead battery recycling rate of 98%, while Europe’s recycling rate is 100%.

  2. Clearing the Air: Why indoor air quality is crucial for schools

    Leave a Comment

    Picture this: A little girl sits in a classroom in her neighborhood elementary school. She’s trying to focus on the teacher’s lesson, but her asthma is acting up again. She’s wheezing and finding it hard to breathe. Her chest tightens. At some point, it gets to be too much. She has to leave school early and head home.

    It’s an imagined scenario, but one that is increasingly playing out in schools everywhere as the impacts of unhealthy indoor air quality become more and more evident – and real.

    Clearing the Air: Why indoor air quality is crucial for schools

    According to the Environmental Protection Agency, indoor air pollution is one of the top five environmental risks to public health; what’s more, the agency estimates that nearly half of all public schools have conditions that contribute to poor environmental quality. Students and staff in schools with poor indoor air quality – caused by pollutants like allergens, dust and mold – can experience coughing, irritated eyes, headaches, allergic reactions and, yes, even aggravated asthma. Beyond the physical symptoms, poor indoor air quality has also been linked to increased absenteeism and lower performance in both students and teachers.

    But just as there’s been an increased understanding of the negative health impacts of poor indoor air quality, there’s also been a greater push to address the issue and make school IAQ clean, healthy and safe for everyone.

    Current trends and insights with IAQ

    Though recognition of the importance of good ventilation, clean air filtration and healthy IAQ had already been on the rise before 2020, COVID-19 helped spotlight the issue even more. As schools worked to make buildings safe for the return of students, many looked into improving IAQ through better ventilation and filtration, which have been shown to reduce airborne contaminants, including viruses, when used in concert with other best practices. Interest in school IAQ is certain to remain high as COVID lingers and schools continue to create healthier environments for staff and students.

    The increased attention on indoor air quality has also revealed a pressing need for smart data platforms that can help building management teams take the guesswork out of IAQ management. Many schools don’t have ways to monitor IAQ, nor are they able to determine when it’s time to make ventilation changes or update filters. Modern systems, complete with IAQ sensors and integrated technology, are becoming more readily available. They can be costly and complex, which can be challenging for schools.

    But there is good news: The federal government has made significant funding available – an estimated $122 billion in American Rescue Plan Elementary and Secondary School Relief Funds – for schools to make IAQ upgrades.

    MERV 13 filters and the benefits for schools

    One thing schools are sure to invest in when making IAQ improvements: MERV 13 filters for their HVAC systems. MERV, which stands for Minimum Efficiency Reporting Value, rates a filter’s ability to capture particles. Though MERV 8 filters are common, those rated MERV 13 or higher can capture smaller particles and reduce the spread of viruses and allergens, thus improving IAQ and, in the long term, student and teacher health and productivity.

    Technostat® is the go-to choice of many prominent filter manufacturers who make the MERV 13 panel filters used in U.S. schools.

    Hollingsworth & Vose: The right choice for healthy IAQ

    Global filtration leader Hollingsworth & Vose has been innovating in the world of filtration for decades. In particular, our Technostat® filter media, which is used in MERV 11-13 filters, is playing a key role in how schools are making improvements to their IAQ. In fact, Technostat® is the go-to choice of many prominent filter manufacturers who make the MERV 13 panel filters used in U.S. schools.

    Why is that? Not only because Technostat® meets stringent industry ratings, but also because it is the leading electret media product in the market. It can capture small particles and offers high efficiency filtration with a low pressure drop, which means cleaner air with lower energy consumption in an HVAC system.

    In addition to Technostat®, H&V offers a range of other filtration solutions that can help schools significantly improve their IAQ, creating better learning environments for students, teachers and staff at a time when the need is greater than ever. Contact us directly for more information.

  3. Celebrate Earth Day With NanoWave® Filter Media

    earth dayWhile Earth Day is an important time to celebrate nature and the beauty of the outdoors, at Hollingsworth & Vose, we are doing our part to make the air quality in buildings safer through filtration solutions that reduce energy consumption and minimize carbon emissions as compared to standard filtration in the market.

    With energy consumption in buildings contributing over 30% of U.S. greenhouse gas emissions, and HVAC equipment accounting for 40% of commercial building energy usage, our team is motivated to help overcome these energy burdens through the introduction of advanced filter media that achieves better and more sustainable outcomes.

    Air filtration is a critical requirement for healthy indoor air quality, but one that often involves making difficult decisions around higher energy expenditure to achieve the increased levels of filtration needed to keep building occupants safe and productive. That’s because it generally takes more energy to move air through higher-grade filters in HVAC systems (such as MERV 13-16), meaning more energy usage is the trade-off for cleaner air.

    When considering indoor air quality, can we live in a safe and more energy-efficient world, having our cake and eating it too? A recent study conducted by on the carbon handprint of our NanoWave® filter media, an industry game-changer given its low-pressure-drop-to-performance ratio, revealed that building owners don’t have to compromise with higher energy usage for a safer indoor environment.

    After reviewing our manufacturing processes and considering the energy use savings against comparable filter media, the study showed that NanoWave® emits 32 times less carbon and generates a savings of -326 kgs CO2e per filter use from cradle to gate. To put that into perspective, those savings are roughly the same amount of carbon emissions that a car ride from Massachusetts to Michigan would generate using regular gas.

    The filtration industry admittedly has much work to do to continue improving manufacturing practices as responsible contributors to the green economy. At H&V, we are passionate about driving sustainable innovation to fulfill our mission of creating a cleaner, healthier, more sustainable world. If you are interested in learning more about how NanoWave® can help reduce HVAC energy consumption and lead to better outcomes for people, buildings, and the planet, please contact us at


    Wishing everyone a happy and healthy Earth Day from the team at Hollingsworth & Vose!
