: "Higher mAh always means better battery." Fact : High capacity cells often have shorter cycle life and higher internal resistance.
If you need a report based on a specific chapter or a more technical angle (e.g., internal resistance measurement, battery analyzers from Cadex), let me know. Also, for legitimate access to the PDF, check with your local library, university database, or directly with Cadex Electronics (they sometimes offer free older editions for educational use).
