I purchased this book partly in desperation because I had obtained 2 brand new laptop batteries and neither would fully charge, they fell short by up to 8-percent of their design capacity. I wondered why. I researched the operation of these SMART batteries and the reference book most frequently recommended for further reading was, 'Batteries in a Portable World'. I had to have it because it might contain the answers to my questions. It was a gamble.
This publication is close to being a decade old and an update must be imminent. However, despite its age it does describe in sufficient detail the operating principle underpinning all the popular forms of rechargeable batteries on the market today, including: Nickel Cadmium, Nickel Metal Hydride, Lithium Ion and other specialised and more unusual batteries and their charging systems.
This is an expensive book but quite frankly I am not aware of a better one at this time. I would purchase an update if one became available because there have been developments in battery technology during the past 10 years.
