What is the specific gravity range of the electrolyte in nickel-cadmium batteries at room temperature?

The specific gravity of the electrolyte in nickel-cadmium (Ni-Cd) batteries at room temperature typically ranges from 1.240 to 1.300. This measurement reflects the density of the electrolyte solution, which consists mainly of potassium hydroxide (KOH) and water. The specific gravity provides important information about the state of charge of the battery; a higher specific gravity indicates a more concentrated electrolyte and often corresponds to a fully charged state.

In the case of nickel-cadmium batteries, this specific gravity range is essential for maintaining proper battery performance and longevity. Monitoring the specific gravity can help prevent issues such as undercharging or overcharging, which can adversely affect the battery's capacity and lifespan. Thus, understanding and adhering to the correct specific gravity range is vital for effective battery management.
