Battery University monitors the comments and understands the importance of expressing perspectives and opinions in a shared forum. Effect of Zapping BU Courtesy of Cadex Figure 2: What causes Cells to Short? There are no store locations at the selected location. This led to the development of capacity estimation technology, as relying on the internal resistance, or CCA on a starter battery is unreliable. This characteristic is visible with most lead- and lithium-based batteries.
