The battery has become our steady travel companion - it helps call a friend; it expands our workplace beyond four walls; and it supports critical missions for people in need.

Performance specifications for batteries and chargers are often based on ideal conditions.

Manufacturers carry out battery tests on brand new equipment within protected environments. In Batteries in a Portable World, Mr. Buchmann observes the battery as used by consumers in everyday life.

The battery handbook addresses the strengths and limitations of the modern battery. It illustrates which battery chemistry is most appropriate for each application. You will learn about charger technology, battery maintenance to prolong battery life and methods to restore weak batteries with a battery analyzer.
