Sustainable storage batteries are critical to successfully integrating renewables into the grid and powering off-grid buildings and microgrids.
Today, lead-acid and absorbent glass mat (AGM) batteries store energy from solar-powered schools and electric vehicles to cell phone towers, trains, and emergency room backup generators.
But how sustainable are they?
In this blog post, you'll learn:
Embracing zero waste in battery production protects the environment and saves money.
For instance, Crown Battery started comprehensive recycling and renewable energy programs decades ago. Building longer-lasting batteries (keep reading to see how) while reducing materials and manufacturing expenses translates into consumer savings – and enables Crown Battery to keep prices low.
Plus, zero-waste practices play a pivotal role in shrinking the environmental footprint of battery manufacturing.
Responsible manufacturing can be cost-effective and ecologically sound – especially when manufacturers rethink production from the ground up and ensure every stage, from R&D to recycling, aligns with sustainability goals.
And in battery making, sustainability starts with battery recycling.
Lead-acid and AGM batteries are 99% recycled – more than an aluminum can (source: U.S. EPA’s “Advancing Sustainable Materials Management: 2018 Fact Sheet”).
They’re continuously turned into new batteries, reducing raw material mining and other environmental impacts.
In contrast, only 5% of Lithium-ion batteries are recycled (source: Chemical & Engineering News, “It's time to get serious about recycling lithium-ion batteries”).

Lead-acid and AGM batteries, particularly those manufactured with renewable energy sources, have significantly lower CO2 emissions than other battery chemistries.
In September 2023, Sphera Solutions released a new study that compared the cradle-to-grave impact of lead-acid and AGM batteries versus Lithium-iron phosphate (LFP) models.
The independent report was commissioned by the Battery Council International (BCI) and the International Lead Association (ILA), following ISO 14040/44 standards.
Sphera Solutions’s lifecycle assessment evaluated everything from raw material extraction and processing to transportation, materials manufacturing, battery assembly, lifetime usage, and end-of-life.
After performing a complete lifecycle analyses of 12V lead-based and LFP batteries for automotive applications, Sphera’s researchers concluded:

You can also lower CO2 emissions and replacement costs by improving battery longevity.
When batteries last longer, you have to replace them less often. That’s good for your wallet and for the environment.
To extend battery life, avoid:
Proper maintenance and usage are crucial to maximize lifespan and minimize operating costs.
To get the most out of your batteries in the shortest amount of time:
Once you understand how to optimize storage, charging, and maintenance, you can mitigate common battery killers – and extend battery life.
Battery longevity and sustainability rely on minimizing mining and improving manufacturing.
And companies that invest in clean, efficient, and ethical manufacturing practices tend to produce more sustainable batteries.
For instance, Crown Battery:
These practices ensure that batteries are not only high-performing but also environmentally responsible.
“People can say whatever they want over the phone and in sales pitches. But when I saw the Crown employees’ attention to detail, how clean the factory was, and the robotic assembly and computerized quality checks – we were sold.
Plus, Crown still makes all their batteries in America, and I like that. They’re an Ohio company, like us.”
