This diagnostic process assesses the state of cost in lead-acid storage cells. It depends on measuring the particular gravity of the electrolyte answer. A specialised instrument is used to attract a pattern of the electrolyte; the instrument then signifies the particular gravity through a graduated scale. For example, a studying of 1.265 signifies a completely charged cell, whereas a studying under 1.100 signifies a discharged state.
The worth of this evaluation stems from its skill to supply a direct indication of the sulfuric acid focus throughout the electrolyte. This focus straight correlates with the vitality saved throughout the cell. Common implementation of this verify aids in figuring out failing cells inside a multi-cell battery financial institution, stopping untimely battery failure and guaranteeing constant energy output. Traditionally, this methodology supplied a comparatively cheap and easy technique of evaluating battery well being earlier than superior digital testing grew to become commonplace.
