Low-Power Battery Configurations

Low-power battery design configurations determine how the battery will provide the most efficient function, how much it will cost at a retail price, and how it will meet the minimum weight and size requirements. The weight requirement may demand the low-density material in the cell, whereas the size specification has to consider the optimum design configuration capable of yielding the smallest size with a desired form-factor. 

Commercially available low-power primary AA batteries known as dry cells mostly come with cylindrical configurations and typically are rated at 1.5 volts (V). These batteries are designed to provide hundreds of nanoamperes to a few millamperes. They generally use lead or aqueous alkaline electrolyte. These cells are best suited for analog cameras, small electronic devices, electronic toys, and flashlights. Specifications of such batteries are summarized in Table 5.1. 

2 Carbon-Zinc Primary Low-Power Batteries and Their Characteristics 

Battery market surveys indicate that C-Zn primary batteries are widely used worldwide for low-power battery applications. The survey further indicates that shelf-life performance has improved 750% and current leakage has reduced significantly during the last 90 years. This particular battery is available in two distinct design configurations, namely the standard version, which uses natural manganese
