I’ve spent years evaluating battery chemistries for EV packs, drones, and off-grid storage—and one question keeps popping up: are lithium-ion batteries considered wet-cell batteries? Short answer: not in the traditional sense. While most lithium-ion cells do contain a liquid electrolyte, they are sealed, non-aqueous systems and are not categorized as “wet-cell” like flooded lead-acid batteries….

If you’ve ever struggled with interference while locating utilities, calibrating instruments, or simply keeping a jobsite safe, you already know that the environment around your work matters. As a safety trainer and field tech who’s set up hundreds of controlled work areas, I can tell you this: you must create a _______ perimeter or buffer…

If you’ve ever popped the hood on a hybrid or electric car and felt that mix of curiosity and caution, you’re not alone. I’ve spent years in the bay and on the training floor, and I’ve learned that when working with HEVs and EVs, precision and preparation matter more than anything. In this guide, I’ll…

I’ve spent years fixing everything from cars to laptops, and one question keeps popping up: where is the battery? Here’s the short answer I’ve learned through countless repairs and diagnostics—the battery is almost always found close to a device’s power entry point or wherever short, sturdy connections make the most sense. In other words, placement…

I’ve spent years testing, evaluating, and writing about what matters most in passenger vehicles—from advanced safety features that quietly save lives to the everyday comfort touches that keep families happy on long drives. When we talk about innovation in passenger vehicles, we’re really talking about the systems, materials, software, and design choices that shape your…

As someone who has advised fleets, lived with EVs in high-rate markets, and tracked energy data for years, I’ve seen a surprising pattern: in many real-world scenarios, electricity is more expensive for car owners than gasoline or diesel fuel. While “electricity is more expensive for car owners than gasoline or diesel fuel” sounds counterintuitive, the…

If you’ve seen headlines declaring that research has shown that electric vehicles are much more likely to present fire risks than gasoline-powered cars, you’re not alone. I’ve spent years analyzing mobility safety data, talking to fire investigators, and reviewing EV battery incident reports. Here’s the bottom line: the topic is more nuanced than a viral…
