As we increasingly rely on batteries to power our daily lives — from cars to smartphones to renewable energy — the question of how healthy these batteries are becomes even more important. Yet, many businesses and industries using batteries today have no reliable way of predicting when they will fail.
BatteryCheck, founded by Michal Sastinsky, offers a simple solution to a widespread problem, giving companies real-time insights into their batteries’ health and future performance. By doing so, businesses can avoid unexpected failures and make smarter decisions about their energy usage. But like most good ideas, BatteryCheck didn’t start out as the product it is today. Much like Michal’s career, the company’s origin story is full of twists, pivots, and learning experiences that shaped it into the game-changing solution it is now.
Michal didn’t always plan to build a battery monitoring company. In fact, the original idea came from his fascination with repurposing used electric vehicle batteries for energy storage. In 2018, Michal saw an opportunity to buy these used batteries and build affordable energy storage systems. But as he dove into the project, a major obstacle emerged: there was no way to accurately tell how healthy these used batteries were. Without that critical piece of information, it was impossible to guarantee how long they’d last or provide any kind of warranty.
“I realized that if I couldn’t predict how long the batteries would last, no one else could either,” Michal explains. “That’s when I had an ‘aha’ moment. Instead of trying to build the storage systems myself, why not create a tool that helps everyone manage their batteries better?”
And just like that, the focus of BatteryCheck shifted from building 2nd life energy storage systems to solving a much broader, industry-wide problem — battery health monitoring. Michal’s idea was simple but powerful: give companies the tools to predict when their batteries would fail and make sure they never had to deal with unexpected downtimes.
Michal’s ability to pivot so seamlessly didn’t come out of nowhere. His career had already been a mix of tech, data, and energy, uniquely positioning him to recognize this gap in the market. After earning a degree in finance and taxes, Michal found himself working in the tech world, selling ERP systems — a type of business management software. Soon, he landed at Microsoft, where he spent eight years developing the company’s IoT (Internet of Things) business in Europe, managing projects across 22 countries.
Here, Michal first became fascinated by the potential of connected devices — things like smart fridges or security systems — that generate data in real-time. This experience gave him a deep understanding of how data could be used to predict behavior and improve outcomes. Michal then spent another four years at Teradata, a global leader in data analytics, where he learned how to make sense of massive amounts of data — skills that would later become essential in creating BatteryCheck.
But Michal’s career wasn’t just about IoT and data. He also spent eight years selling lithium batteries and graphene ultracapacitors, which gave him a front-row seat to the challenges businesses face when it comes to managing energy. These combined experiences were the perfect ingredients for what would eventually become BatteryCheck.
Michal isn’t tackling this massive challenge alone. His co-founder and CTO, Rastislav Struhar, plays a crucial role in the company’s success. With over 12 years of experience in backend applications, cloud infrastructure, and data collection, Rastislav is the technical mastermind behind BatteryCheck’s platform. He’s the kind of person who loves diving into complex problems and finding innovative solutions that no one else has thought of yet.
“Rastislav is always learning, always trying out new ideas,” says Michal. “He brings that creative technical spark, which is exactly what we need to build something as sophisticated as BatteryCheck.”
Together, they’ve assembled a team of experts, including data scientists and industry advisors, who understand the deep complexities of battery chemistry, energy, data, and analytics and already have two patents. It’s this blend of technical and business expertise that sets BatteryCheck apart from other battery monitoring tools.
So, what does the future hold for BatteryCheck? According to Michal, the goal is simple: make battery monitoring as easy and accessible as possible. His vision is for BatteryCheck to become the go-to solution for companies that need to understand their batteries but don’t have the in-house expertise to do it themselves.
“We want to become the Google Analytics of batteries,” Michal explains. “Just like you can go online and track how well your website is doing, we want companies to be able to easily monitor their batteries — whether it’s for electric cars, energy storage, or critical backup systems. It should be as simple as logging in, uploading your data or connecting via API, and getting real-time insights.”
Michal sees a future where any company — big or small — can use BatteryCheck to predict battery failures, optimize energy usage, and ultimately save money. The platform is designed to be intuitive and easy to use without requiring any technical expertise. Michal and his team are focused on building something that not only solves today’s problems but also anticipates the needs of tomorrow as batteries become even more integral to the world’s energy infrastructure.
As the world becomes more dependent on batteries to power everything from cars to homes, BatteryCheck is poised to become the go-to solution that helps businesses keep their batteries healthy and operational. With Michal’s vision and drive, the company is set to change how we think about energy management, one battery at a time.
