Critical Performance Characteristics of Rechargeable Batteries

Two of the most critical performance characteristics of a rechargeable battery are the energy density (Wh/L) and the specific energy (Wh/kg). From these 

Battery Type and Classification Specific Energy (Wh/kg) Energy Density (Wh/L) 

These estimated values are batteries developed five years ago and are accurate within 5%. The same batteries are now improved by 5 to 10%. Reliability, efficiency, and longevity of these batteries will be specified in subsequent chapters. 

2 Capabilities of Widely Used Rechargeable Batteries in Commercial Applications 

Specific energy (Wh/kg), energy density (Wh/L), longevity (operating hours), and self-discharge (percent per month) and specific power (W/kg) are given serious consideration in the selection of rechargeable power batteries for commercial applications. Performance characteristics of commercial batteries are summarized in Table 1.2.
