Change-log of “Batteries in a Portable World,” 4th edition: Chapters 4 - 10

The 4th edition of Batteries in a Portable World contains large volumes of firsthand information that is not available in the 3rd edition of the book with same title. The 4th edition would have grown beyond 360 pages had the layout not been tightened and some text removed and condensed. To examine topics of interest, the author checked traffic on and found constructive pointers. The most visited webpages are [1] How to Prolong Lithium-based Batteries, [2] Charging Lithium-ion, [3] Charging Lead Acid, [4] Serial and Parallel Configurations, and [5] Absorbent Glass Mat (AGM).

All chapters were updated and the number of tables and figures was increased from 173 in the previous version to 248. The 3rd edition has 318 pages; the 4th edition is at 360. The table below lists the “must have” content that is relevant today and is not present in the 3rd edition. Chapters 1 - 3 can be found here.
