{ "item_title" : "Build Your Own Battery", "item_author" : [" Jose Valladares "], "item_description" : "Most books about batteries ask you to read. This one asks you to build.Start with a lemon, two pieces of metal, and a multimeter - and by the final chapter you'll understand the same principles that run the battery in your phone, the pack in an electric car, and the storage systems powering entire cities.Build Your Own Battery is a hands-on handbook that turns one of the modern world's most essential technologies into something you can hold in your hands, measure, and genuinely understand. You won't just read about voltage and current - you'll watch them appear on your own meter, discover why a cell can read a healthy voltage yet still fail to light an LED, and learn to think like the scientists who spent two centuries solving these exact problems.A clear, safety-first system runs through the whole book: BUILD - Real projects you make from ordinary, low-cost materials: lemon cells, saltwater batteries, a voltaic pile, and a reusable test station, each with full instructions, expected results, and troubleshooting.UNDERSTAND - The batteries you use every day - alkaline, lithium-ion, lead-acid, and more - explained so you finally know what's inside them and how to choose.EXPLORE - The frontier and the fringe: flow batteries that store power for the grid, metal-air cells that breathe, molten-salt systems, and the experimental chemistries still taking shape in laboratories.Inside you'll learn: How every battery works, from the humblest cell to the lithium-ion familyWhy there is no single best battery - only the right one for each jobHow the major chemistries connect in one branching family treeHow to handle, choose, and dispose of batteries safely and responsiblyWhat's real, what's emerging, and what's still hype in the world of next-generation batteriesWhether you're a curious beginner, a hobbyist, a student, a teacher looking for real experiments, or simply someone who wants to understand the technology quietly powering modern life, this book meets you where you are and takes you further than you expect - one measured, hands-on step at a time.No lab required. Just curiosity, a few household materials, and a willingness to build.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/9/79/819/206/9798192065723_b.jpg", "price_data" : { "retail_price" : "14.99", "online_price" : "14.99", "our_price" : "14.99", "club_price" : "14.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
