About this book
E-book readers are prized for their long battery life, but that lithium-ion cell inside will eventually lose capacity, swell, or fail. Whether you are a technician replacing batteries daily, a library maintaining a fleet of devices, a reseller sourcing reliable stock, or a user who wants to get five more years out of a favorite reader, this handbook gives you the exact, practical knowledge you need. It dismisses myths, explains real-world capacity ratings, and walks you through safe removal and replacement procedures with specific tools and precautions.
The book goes far beyond the basics. It breaks down the different form factors (like the common 3.7V pouch cells used in most readers), how to read the codes printed on an OEM battery, and how to spot counterfeit cells that could damage the device or pose a fire risk. Step-by-step chapters cover installation, from pre-installation checks to post-installation calibration, and provide a diagnostic flowchart for common problems like rapid drain, failure to charge, and zero-voltage cells.
For professionals, the latter half of the book is a business manual. It analyzes the market structure, from major OEM suppliers to third-party aftermarket manufacturers, and presents concrete business opportunities—from a mobile repair service to private-labeling replacement batteries. It concludes with a look at emerging technologies like solid-state batteries and the regulatory landscape of battery transport and disposal, followed by a curated FAQ and a glossary of terms.
Reader Reviews

★★★★★I’m a repair tech and I bought this to have a single reference for the constant flow of Kindle and Kobo battery swaps. Chapter 1’s breakdown of charge cycles and the so-called '1000-cycle myth' is solid, and the diagnostic flowcharts in chapter 5 saved me a few hours this week. My main gripe is that the spec tables in chapter 2 don’t list specific model numbers for batteries made after 2023, so I still have to cross-reference supplier sites sometimes. That’s fine, it’s a book, not a live database, but it annoyed me enough to knock a star off. Still, good practical content for the money.

★★★★★The book is well-organized and the tone is appropriately dry and factual, which I appreciate. I found the section on identifying counterfeits really useful—the bit about the weight difference and printing quality was something I hadn’t seen spelled out before. I was hoping for a bit more depth on the electrical characteristics, though, like what exactly a BMS does in these tiny batteries and why some packs have three wires and others have five. The explanation felt a little skimmed over. It's a good resource for a generalist, but I'm not sure it'll be the last word for a hardcore electronics person.

★★★★★This is the book I’ve been looking for since I started repairing e-readers as a side business. It’s direct, technical, and accurate—no filler. The installation chapter alone is worth the cover price: the tip about using a playing card to clip the plastic clips after heating the seam exactly matches what I’ve learned from doing hundreds of these, just without the trial and error. I also appreciate the business chapter; it gave me clear numbers on wholesale margins for private-labeling decent 3.7V 1000mAh cells, which I’d been terrible at estimating. I keep it on my bench, right next to the adhesive tape.
